8 Best Drill Sharpeners [2022 Updated]

For some it is a controversial instrument, with performances not comparable to those of a bench grinding wheel; for others, however, it represents a very useful resource. So let’s see which are the most requested sharpeners on the market.

1. DEWALT 20V Max Cordless Drill / Driver Kit,


Drill Doctor is a brand owned by the US company Darex LLC, which specializes in manufacturing industrial sharpeners for drills, knife and tool sharpeners and drill bit sharpeners for hobbyists.

The Drill Doctor 750X is precisely a model intended for hobby use and occupies the first place of our ranking as it is one of the best sellers online; this sharpener, in fact, is appreciated both for the possibility of adjusting the angle of incidence of the grinding from 115 to 140 degrees, and the quantity of material to be removed, in order to extend the useful life of the tips to the maximum.

The diamond wheel can be easily replaced and is capable of sharpening any type of tip whose diameter is between 2 and 19 millimeters. The only flaw, unfortunately, is the documentation totally devoid of Italian translation, so the approach to use is certainly not the simplest.

Pros

Reliable: Among the different models intended for hobby use, Drill Doctor 750X is the most expensive but it is also the best drill sharpener in terms of performance and reliability.

Versatile: In addition to the possibility of sharpening tips for micromotors, hobby drills and professional drills, the diamond wheel is able to sharpen any type of material, from hard metal to cobalt.

Adjustable: Drill Doctor 750X allows you to adjust both the angle of the sharpening and the amount of material to be removed, thus avoiding unnecessary waste.

Cons

Instructions: Unfortunately, both the documentation relating to the precautions for use and the instructions are only available in English.

2. GardenJoy Cordless Power Drill Set: 21V Electric Drill

 
Another very popular device is the one produced by the German firm Holzmann Maschinen, which is characterized by a far more affordable price than the Drill Doctor.

Compared to the model examined previously, the BSG13E has the advantage of offering construction quality and reliability of the same level, but at the cost of less versatility and a lower level of performance. The device, in fact, is able to sharpen only the drill bits whose diameter varies from 3 to 13 millimeters, which limits its use exclusively to the amateur and domestic environment.

However, for those who have no particular needs other than the good workmanship of the product and its durability, the Holzmann product represents the ideal solution, above all thanks to the low price. The only flaw is that there are no spare parts, so in case of failure you have to replace it with a new sharpener.

Pros

Price: Although with a top price, the Holzmann sharpener is still a device belonging to the range of products at low prices, so it is easily accessible and is especially suitable for savers.

Easy to use: Being a device intended purely for hobby use, it has no adjustments and therefore extremely easy to use, even for a beginner.

Average quality: The performances offered and the quality level of the materials and assembly are fully within the limits of its category.

Cons

Spare parts: The only replaceable piece is the grinding wheel; for all the other components, however, there are no spare parts, and in the event of breakdowns or breakages, a new sharpener must be purchased.

3. COMOWARE 20V Cordless Drill,

 
Another very interesting economic device is the one proposed by the French company Ribimex, specialized in the production of equipment, tools and accessories for DIY and gardening.

The main feature of the PRIAF716, in fact, is that of being a sharpener equipped with a double head: one allows you to sharpen tips whose diameter varies from 3 to 10 millimeters, while the other is compatible with tips from 8 to 16 millimeters in diameter. ; consequently it can be useful both in the hobby field and for those who own professional drills, which usually use bits whose shank has a minimum diameter of 12-13 millimeters.

  • 【25+1 Position Clutch & 266 In-lbs Max Torque】 This cordless drill's clutch provides precise control...


A further advantage of this Ribimex sharpener is to be able to adjust the height of the grinding wheel, and then set it to remove a minimum amount of material so as not to wear the tip too much. The grinding wheel, however, tends to wear out quickly, and the device is not very accurate.

Pros

Double head: The two heads supplied allow to widen the compatibility with the diameters of the bits, also including most of those used by professional drills.

Adjustable: Unlike other economic sharpeners, the Ribimex PRIAF716 offers the possibility to adjust the height of the grinding wheel, and therefore to minimize the removal of material from the tip.

Affordable: The price is low and it is easily accessible even for those on a limited budget.

Cons

Accuracy: Unfortunately it lacks in terms of accuracy, moreover the grinding wheel tends to wear out quite quickly; but considering the price you can’t expect more.

4. BLACK+DECKER 12V MAX Cordless Drill

 
The PRIAF70 is also produced by the Ribimex company, and is characterized by a lower price than the model examined previously. In principle it is the same device, in fact it uses the same 70 Watt motor and the lower part is similar in all respects to the PRIAF716.

The primary difference between the two, therefore, comes down exclusively to the fact that the PRIAF70 is equipped with a single head, compatible with tips from 3 to 10 millimeters in diameter.

  • LIGHTWEIGHT DRILL AND SCREWDRIVER - Lightweight cordless drill and screwdriver for household tasks
  • COMPACT DESIGN - 35% Smaller than previous 12V Drill/Driver models for easy maneuvering


The grinding wheel can be adjusted in height, as in the model examined previously, but in any case it is not suitable for sharpening Widia or particularly hard tips, and if too much pressure is exerted it tends to slow down and stop. If we limit ourselves to purely domestic and amateur use, however, the PRIAF70 does its job discreetly and is also quite reliable.

Pros

Adjustable: Like the PRIAF716, the PRIAF70 is also characterized by the possibility of adjusting the height of the grinding wheel in order to minimize the consumption of the tip during sharpening.

Amateur: Its performances are modest, but ideal for those with purely amateur needs and an occasional frequency of use, in order to keep the bits in good condition for occasional housework that requires the use of the drill.

Spare wheels : The further advantage of the PRIAF70, but also common to other Ribimex sharpeners, is the ease with which it is possible to find spare wheels.

Cons

Small diameters: In addition to the inherent limitations due to its nature as an inexpensive device, the PRIAF70 has a certain difficulty in sharpening smaller diameter drills.

5. GALAX PRO 12V Lightweight Cordless

 
The Proxxon BSG 220 ranks fifth in our ranking, but only by virtue of the fact that it is a niche product intended for professionals who use high precision drills.

The BSG 220 is in fact expensive, but the price is still lower than the Drill Doctor 750X, because its compatibility is limited to bits from 3 to 13 millimeters in diameter; however it is assembled by computerized numerical control machines and is extremely precise, it allows you to manually adjust both the distance from the grinding wheel and the position of the tip on its axis, in order to also produce the correct discharge angle, and is equipped with a grinding wheel at the corundum able to sharpen even Widia tips.

  • Integrated design: streamlined body, built-in battery, USB interface charging, a bright LED light for...


If you are wondering where to buy a new professional sharpener for high precision tools, then the Proxxon BSG 220 is the ideal answer to your needs.

Pros

Solid and sturdy: The BSG 220 is entirely made of die-cast metal and the base is also prepared for fixing to the workbench, in order to work with maximum precision.

Adjustable: Both the distance of the tip from the grinding wheel and the position of the same can be manually adjusted to fine; the arm that holds the tip can be oriented so as to move it on its axis, in order to also file the unloading angle

Spare disc: The package also includes a second spare corundum disc, and you can also purchase additional accessories, such as adapters for drill bits from 1.5 to 3 millimeters and silicon carbide discs.

Cons

Price: The cost is perfectly proportionate to the quality of the device and its performance, but still remains quite high and makes it a niche model.

6. GardenJoy Electric Power Drill Cordless:

 
The universal sharpener 2001 is the cheapest model reviewed in our guide, and is manufactured by the British firm Multi-Sharp. This is obviously a tool intended for hobby use, but it is designed for sharpening tips made of HSS alloy, or super-fast steel, even if it is limited only to those with a diameter from 3 to 13 millimeters.

The distinctive feature of this sharpener, however, consists in the mask that allows you to adjust the angle of the sharpening, and in the possibility of adjusting the position of the wheels in order to sharpen both normal drill bits and those with a central spur.

Despite the positive characteristics, however, it still remains an economic product and the limitations are manifested above all in the low level of precision and in the speed with which the grinding wheels are consumed. Furthermore, it is extremely difficult to work on those with a diameter of less than 5 millimeters, due to the difficulty in aligning the tip.

Pros

HSS: Despite the high consumption rate, the grinding wheels are also capable of sharpening points made of HSS steel alloy and those with cobalt, but a certain degree of experience is still required.

Jig: The presence of the shaped jig allows you to sharpen different types of tips, including those with a central spur, but also in this case you have to take the hand in order to obtain a good alignment.



Price: The negligible cost to say the least is one of the greatest advantages of this sharpener, which consequently is recommended above all for savers.

Cons

Performance: In addition to requiring a lot of practice to use it well, the Multi-Sharp 2001 has a very limited level of performance, especially in terms of accuracy.

7. BLACK+DECKER 12V MAX Drill & Home Tool Kit,

 
Powerplus POWX1035 is an extremely versatile tool, as it allows not only to sharpen drill bits but also chisels and scissors and knife blades. As often happens with low-cost tools that promise multifunctional performance, however, the Powerplus sharpener lives up to expectations; the “grinding wheel” of the device, in fact, is nothing more than a sheet coated with abrasive material, moreover asymmetrical, so both precision and effectiveness are at the lowest levels.

According to the opinions of some buyers, however, by replacing the grinding wheel with a better quality one, we end up with a tool that, although limited to purely amateur applications, is definitely useful and functional.

Sale

  • 12V Max Lithium drill is 35 percent more compact than previous version

The only real limitation consists precisely in the dimensions that the grinding wheel must have, namely 55 mm in diameter with an 8 mm central hole, which make it quite difficult to find.

Pros

Multifunction: The primary feature that has attracted the attention of buyers to this sharpener the most is its multifunctionality; in fact it can sharpen drill bits, chisels, scissors and knives.

Convenient: Given the characteristics of the device, the price is very affordable and this marks a further point in its favor; obviously it still remains a cheap product so the quality of the materials is certainly not excellent.

Easy to use: Although the instructions are kept to a minimum, the Powerplus sharpener is a very intuitive tool and therefore extremely easy to use.

Cons

Wheel : The supplied wheel is practically a toy, so to get decent performance you need to replace it with a better one that has the right size.

8. BLACK+DECKER 12V MAX Drill & Home Tool Kit,

 
We conclude our ranking of the best sharpeners of 2021 with a tool designed above all as a support, and therefore to be used together with a bench grinder or a grinder.

The Article 3200 produced by the German company BGS Technics, in fact, is a two-axis goniometric turret with micrometric adjustment, made entirely of aluminum alloy and compatible with all tips from 3 to 19 millimeters in diameter. The turret has the advantage of being cheap and functional, but it is intended for those who already own a bench grinder because its function is limited exclusively to the support and movement of the tip during the sharpening work.

Moreover, precisely because of its dynamics of operation, it requires a lot of practice and attention before guaranteeing good results, so it is recommended above all to more experienced craftsmen and hobbyists, who already have a well-equipped laboratory.

Pros

Micrometric adjustment: The turret has micrometric adjustment on two axes, so it is ideal for sharpening the tips precisely and giving the correct relief angle.

German quality: Although it is a cheap tool it is well made; it is made almost entirely of aluminum alloy with small steel details, and is obviously designed for attachment to the workbench.

Economical: It costs little, but after all it is also a simple support for the tips designed especially for those who already have a laboratory, or a well-equipped workspace.

Cons

For experts only: Its features make it suitable only for hobbyists and experienced craftsmen who already own a good bench grinder.

How to choose the best drill sharpeners

Can’t decide which drill sharpener to buy? Do not worry, let’s find out together what are the typical characteristics of this device and which requirements to give higher priority.


Professional and amateur needs

Those who often use the drill are aware of the importance of always keeping the tips in good condition, so as to prevent them from breaking or causing damage to the walls or materials on which they are used. It is natural for a professional to acquire the good habit of sharpening points; it is a little less so for simple DIY enthusiasts instead, who tend to underestimate this practice until they come up against the problems deriving from using a tip in bad condition for the first time.

Usually most professionals rely above all on their experience and acquired dexterity, and to sharpen the drill bits they use the bench grinder to have greater control and set the tip discharge angle in an optimal manner.

This method, however, even if it has the advantage of offering better results, requires experience and more time; the sharpeners, on the other hand, are much more effective in terms of speed, but the models capable of satisfying the professional user are very expensive and therefore not very accessible for a simple DIY enthusiast.

For the latter, therefore, all that remains is to move towards a medium-low range model; However, to understand how to choose a good cheap drill bit sharpener, you need to know what are the characteristics to pay attention to.

The diameter of the tips

Versatility is important, for example, but up to a certain point; if you are ready to spend big bucks on a high performance sharpener, then there will be no problems whatsoever. If, on the other hand, you have to deal with a limited budget, then it is useless to be dazzled by the promise of being able to sharpen large diameter drills.

The tips whose diameter exceeds 10 millimeters, in fact, are usually used only by professionals as they are used to pierce concrete and other more or less hard materials; in the hobby and domestic field, on the other hand, 10-13 mm bits are used much more rarely, unlike the smaller diameters.

The exception to the rule is only the tips whose diameter varies from 1.5 to 3 millimeters, which are intended for precision work and therefore can be used both in the amateur and professional field.

If you have to choose a drill sharpener of the hobby category, therefore, know that the possibility of sharpening large diameter drills is not a fundamental requirement, especially if your drill has a chuck that allows you to mount drills up to a maximum diameter of 12- 13 millimeters.


The adjustment of the inclination

Furthermore, the possibility of sharpening large diameter tips in hobby sharpeners is also often limited by the fact that the latter have low-powered motors, and that when pressure is exerted against the grinding wheel, the latter tends to lose speed and effectiveness.

A very important aspect to pay attention to, however, is the possibility of adjusting the axis of the tip; not all sharpeners are equipped with this important function, in fact, which is essential to give the tip the correct relief angle.

Hobbyists who are already lucky enough to own a bench grinding wheel, for example, can save further and opt for the purchase of a goniometric turret, that is a special sharpener consisting of a simple metal support to be fixed to the workbench, near the grindstone. This support, in fact, is equipped with a turret whose inclination can be adjusted at a micrometric level, and is ideal for those who want to sharpen the tips as precisely as possible.

How to use a protractor turret

The characteristics of the tool

The protractor turret is the most characteristic of the sharpeners but it is also the one that requires the most practice to ensure good results, which is why it is preferred above all by professionals and more experienced hobbyists.

The main advantage of this type of sharpener is given above all by the reduced cost of the tool, since it is a simple metal support without motor and grinding wheel; the disadvantage instead consists precisely in the fact that you must already have a bench grinder to be able to use it.


The principle of operation

The goniometric turret consists of an articulated support equipped with a guide where to insert the tips, which are locked in position by means of the special bolts. The support must be fixed to the bench, on the right side of the grinding wheel and at a distance such as to allow the tip to be brought closer to the disc of the grinding wheel by adjusting the distance using the appropriate micrometric adjustment knob.

Between the guide and the support there are also the butterfly screw that allows you to adjust the angle of inclination and the articulated joint that allows you to manually move the guide to the right and left, in order to perfectly orient the cutting edges of the tip.

How to sharpen the tips with the turret

The goniometric turret guide does not have a large enough tolerance regarding the diameter of the tips, and is generally capable of accommodating tips ranging in diameter from 3 to 20 millimeters.

The tip must be inserted into the guide making sure that the cutting edge to be sharpened is perfectly parallel to the surface of the grinding wheel and to do so, in addition to placing it in the right direction on the guide, it is necessary to loosen the butterfly screw that adjusts the inclination in order to perform alignment manually. Near the butterfly screw there are also notches that show the most common angles of inclination based on the type of tip to be sharpened.


Once the inclination has been adjusted, the butterfly screw and the tip have been locked on the guide, just turn on the grinding wheel and as soon as the disc reaches maximum speed, slowly move the guide to the right and left until the cutting edge has been sharpened properly. At this point you need to turn off the grinding wheel, unlock the tip and rotate it to put the other cutting edge in position, lock it again and repeat the procedure to sharpen it.

Frequent questions

How does a drill sharpener work?

The sharpener is a device specially designed to facilitate the sharpening process of the cutting edges of drill bits as much as possible, which requires a lot of experience and extreme attention to be performed manually. Simple DIY enthusiasts, on the other hand, can take full advantage of these tools, and above all they can sharpen their tips with maximum safety.

The grinding wheel, in fact, is positioned inside the sharpener, which on the upper or front part has the entrance holes where the points are inserted. To use it, therefore, just turn it on and insert the tip into the hole with the corresponding diameter, and then exert a slight pressure against the grinding wheel.

In this way there is no danger that the hands accidentally come into contact with the grinding wheel, nor that the sparks produced may hit the face or end up on flammable material, as the grinding takes place inside the machine.


How much does a drill sharpener cost?

The price can vary from about 25 to 3,000 euros depending on the model chosen, also taking into account the models intended for professional and industrial use. The point sharpeners for hobby use can reach a maximum ceiling of about 500 euros, beyond which one actually enters the category of professional machines in all respects. The models that fall into the highest range of the hobby category, however, whose cost ranges from 200 to 500 euros, in most cases are characterized by a level of performance that is able to satisfy even professional craftsmen.

As regards the hobby category, in fact, the characteristics possessed by the sharpeners that are placed at the top of the range in terms of price, are the same as those possessed by the higher-cost professional equipment: versatility, the possibility of adjusting the inclination of the tip and the power. of the engine.

The most common tip sharpeners for hobby use, on the other hand, are those found in the medium-low range, where prices range from about 25 to 150 euros. In fact, with the exception of power, most of the models available that fall into this range have the same characteristics as the more expensive models, but their yield is obviously lower, both in terms of actual performance and the quality of the materials used. manufacturing and assembly.
