7 Best Bench Grinder Wheels for Sharpening [2022 Updated ]

At the top of our ranking you will find hobby-grade bench wheels, but of medium-high range; the professional ones, in fact, while offering superior performances, are also characterized by a decidedly higher cost.

1. Valex EX150 / 200 combined bench grinder 250 W

 
The Valex EX150 / 200 bench grinder is a combined grinder, instead of having the double axial coupling of the classic type, instead, it has only one while the second is angled in order to allow the use of grinding wheels with a larger diameter.

In fact it is designed to mount both grinding wheels and discs with a diameter of 150 mm and water wheels with a diameter of 200 mm; it is driven by a 250 Watt electric motor that generates an idle speed of 2,950 rpm and is also equipped with an adjustable spark arrestor screen.



According to the opinions of the buyers, the EX150 / 200 is the best bench wheel for those who have needs of use that go beyond the purely hobbyist sphere; Valex, in fact, ensures a good compromise between the level of performance offered, quality and cost, and ranks first among the best-selling models online.

Pros

Water wheel: Valex is one of the few bench wheels in the hobby category to allow the assembly of wheels of different diameters: both 150 and 200 millimeters; and is also designed to work with water ones.

Powerful: The engine absorbs less energy than other similar models, but offers the same performance in terms of speed, which reaches 2,950 rpm at no load.

Versatile: The possibility of mounting wheels and brushes of different diameters makes it far more versatile than standard bench wheels which are limited exclusively to a diameter of 150 millimeters.

Versus

Hobby: The continuous use time recommended by the instruction manual must not exceed 5-10 minutes at the most; in fact it is a hobby machine.

2. Femi 36N laboratory cleaning grinder

 
The one produced by the Bolognese company Femi is a bench grinding wheel characterized by a decidedly powerful motor, 450 Watt, with connection of 150 mm wheels and brushes. The 36N is an extremely versatile machine and can be used for grinding, grinding, cleaning and polishing; in addition to the wheels and brushes, in fact, it is also designed for the assembly of abrasive belts.

It has well made and adjustable protection screens, and the one on the right side also carries the connection for the suction hose. The motor is induction, but despite being powerful and silent it tends to slow down if you press too hard against the wheels, furthermore the assembly is not perfect and the machine tends to generate a lot of vibrations; Consequently, the Femi bench grinding wheel is recommended above all for the processing of small pieces or in any case for a mainly hobby use.

Pros

Abrasive belts: The diameter allowed for the grinding wheels and brushes is only 150 mm, on the other hand the Femi 36N is also prepared for the assembly of abrasive belts on the side of the brushes.

Suction: Obviously it does not have a vacuum cleaner, but the metal protection of the brush has a hole for connection to a tube to suck up the dust produced during processing.



Powerful: The motor has a power of 450 Watts and generates a no-load speed of 2,800 rpm, but being induction it is relatively quiet.

Versus

Vibrations: Unfortunately this is a flaw common to almost all hobby-grade bench wheels, and which makes it necessary to fix the machine to the bench with bolts.

3. Fervi Art. 0510 combined bench grinder

 
The Fervi 0510 bench grinding wheel has many points in common with the Femi 36N examined previously, in fact it is a combined wheel set up both for the assembly of grinding wheels and brushes with a diameter of 150 millimeters.

It is also designed to be bolted to the workbench, in order to increase stability; the motor has a power of 350 Watts capable of generating a maximum idle speed of 2,950 rpm, and is also equipped with an adjustable protective screen.



Like the Femi wheel, however, the Fervi also suffers a lot from the vibrations generated by the engine, above all due to the assembly not perfectly aligned with the rotating shaft; there are also other small secondary defects, such as irregularities on the metal box that protects the brush and the coarse paint. Therefore, the Fervi 0510 is also a bench wheel recommended above all for non-intensive hobby use.

Pros

Electric consumption: The engine generates a respectable speed, 2,950 rpm, but with a lower energy absorption than other models, so it has the advantage of consuming less.

Adjustable: Both the spark protection screens and the work surfaces are adjustable according to the needs of the case.

Solid: The manufacturing materials are of good quality, although the same cannot be said for the assembly and finishes, so the Fervi is a solid and resistant machine.

Versus

Finishes and vibrations: The finishes are quite coarse, as mentioned before, and the Fervi also suffers from the problem related to the vibrations generated by the rotary shaft.

4. Einhell TH-BG 150 bench grinder

 
To all those who are wondering where to buy a bench wheel that is of good quality but available at low prices, then we suggest that you take a look at the TH-BG 150 combination grinder, produced by the well-known German company Einhell.

This Einhell bench wheel, in fact, stands out above all for its competitive price to say the least, thanks to which it has become very popular in the range of buyers made up of hobby and DIY enthusiasts; despite being made with good materials and equipped with all the typical features of a professional model, such as adjustable worktops, screens and side protections, it still remains an economic model.



Consequently, the assembly is not perfect, the rotary shaft is slightly unbalanced and the grinder vibrates so much that it must necessarily be bolted to the workbench; for occasional and non-professional use it’s just fine though, especially considering the price.

Pros

Economic: One of the strengths of the Einhell bench wheel is its price, which is highly competitive compared to the standard average of the models examined above.

Compact: The dimensions are slightly smaller than those of the other models, consequently the Einhell bench wheel is more compact and takes up a smaller footprint, so it is ideal for those with space problems.

For hobby: Its characteristics make it suitable for DIY lovers who only delight in their free time; in fact it is recommended above all for amateurs who do not have great needs.

Versus

Vibrations and assembly: Unfortunately it is assembled in an approximate way, the off-center shaft generates strong vibrations that further affect the sealing of the pieces.

5. Bosch Professional GBG 35-15 bench grinder

 
The Bosch GBG 35-15 bench grinding wheel, on the other hand, is the most expensive specimen in our ranking, but it is also the one that offers the best performance in all respects. In fact, it features a new 350 Watt induction motor that generates an idle speed of 3,000 rpm, almost completely vibration-free and extremely quiet.

It houses wheels with a diameter of 150 millimeters and is made with first choice materials, assembled with care and precision. Despite the excellent premises, however, the GBG 35-15 is the entry level model, so while offering professional performance it is quite sensitive to prolonged use; if it works continuously for an hour, in fact, the engine tends to heat up a little.



For those who use it irregularly and for jobs lasting less than an hour, however, it is an excellent machine, whose only limit is the inaccessible price.

Pros

Professional: Among the various models examined in our ranking, the GBG 35-15 is the only one to belong to the professional category, although it is still an entry level model.

Workmanship: The materials of manufacture are of first choice and the assembly is excellent, so the engine is very quiet and does not generate vibrations.

Finishes: From spark arrestor screens to protective casings and adjustable work surfaces, the Bosch Professional bench grinding wheel borders on perfection even in terms of finishes

Versus

Prolonged use: The Bosch Professional can also be used for a long time, but you still have to be careful with the engine because at a certain point it starts to heat up.

6. Ferm BGM 1020 combined grinder P36 and P80

 
With the Ferm bench wheel we return to models intended purely for hobby and do-it-yourself use. The BGM 1020 is a combined bench wheel, that is, it is able to mount wheels and brushes with a standard diameter of 150 mm but with different thicknesses, in this case 20 mm on one side and 40 on the other.

This makes it extremely versatile as far as applications are concerned, it is also equipped with a motor that absorbs only 250 Watts of power but is able to generate a speed similar to that of the more powerful models: a good 2,950 rpm.

It is also equipped with work shelves and protective screens, both adjustable, and is designed to be bolted to the workbench; although the materials and assembly are of good quality, however, the BGM 1020 tends to vibrate more than it should because the wheels supplied are not well ground.

Pros

Versatile: Although limited to wheels and brushes with a diameter of 150 millimeters, the Ferm bench grinder has the advantage of being able to mount both 20 millimeters and 40 millimeters thick ones.

Electricity consumption: Also in this case we are faced with a bench grinding wheel that develops 2,950 revolutions per minute with a power absorption of just 250 Watts, therefore more virtuous from the point of view of electricity consumption.



Accessories: Also included in the package are the two wheels, one 20 millimeters and the other 40 millimeters thick, both with a diameter of 150 millimeters, so it is ready for work.

Versus

Vibrations: The problem of vibrations, in this case, is generated in part by the machine and in part by the grinding wheels supplied, which, being cheap, are not properly ground.

7. Fartools One TX 150B mola da banco 150 mm

 
We conclude our ranking of the best bench wheels of 2021 with the cheapest of the models we have compared: the Fartools One TX 150B. The Fartools bench grinding wheel is driven by a 150 Watt electric motor that generates a speed of 2,840 rpm, and is equipped with couplings for discs with a 150 mm diameter hole.

It also has anti-spark screens in transparent polycarbonate, in order to guarantee maximum safety during work, and is able to grind, sharpen and sand different types of materials according to the type of disc mounted.

Obviously it is an economic model, so it is perfectly functional only for hobby and amateur use; its main limitations are represented by the vibrations generated and by the difficulty in holding up under stress, since the engine makes a lot of effort and its performance drops drastically.

Pros

Price: It is the cheapest among the bench wheels examined in our guide, and therefore it is recommended above all for those who have occasional use needs and of a purely amateur level.

Power: It reaches the considerable speed of 2,840 revolutions per minute with a power consumption of only 150 Watts, which further underlines the hobby vocation of the Fartools bench wheel.



Compact: The small size makes it ideal for amateurs who do not have a real laboratory, but only a small space. The small footprint also facilitates the possible storage of the machine when not in use.

Versus

Vibrations and effort: There is no need to add anything else about vibrations; it is also advisable not to press too hard against the wheels or the engine goes under load and drastically drops the revs.

How to choose the best bench wheels

The correct definition is bench grinder, and it is a stationary machine of compact size used for a wide range of applications, but especially for the machining of small pieces.


For manual use or with the sander

To understand how to choose a good bench grinding wheel, you must first know the strengths and weaknesses of this power tool, especially in relation to its category. The models intended for hobby use are relatively cheap, in fact, but are more affected by the intrinsic limitations of this machine, which mainly concern noise and vibrations, but let’s go in order.

If you find it difficult to identify which bench wheel to buy, the best thing is to focus first on the type of use you need to make of it. In the case of purely amateur needs, in fact, the purchase of a high-end model is almost superfluous, regardless of the benefits related to yield and performance.

The reasons are above all of an economic nature, because the cost of a bench grinding wheel can range from 30 to 1,000 euros and more, depending on the model; all those included in the price range from about 30 to 100 euros belong to the hobby category, while from 100 euros upwards there are semi-professional and professional models.

The hobby category models

The difference in price between a hobbyist and a professional machine is therefore considerable, but the cost is not the only thing that makes the difference. The models intended for hobby use, in fact, despite being made with good quality materials, are characterized by coarser finishes and assembly; the defects common among amateur bench wheels, in fact, mainly concern the vibrations, which are generated not so much by the motor itself as by the rotary shaft, which in most cases is slightly offset, and by the wheels that are not well ground .

In spite of these limitations, however, if the use of the machine is occasional and limited to short work sessions, then you can also do without spending a fortune. The problem of vibrations, in fact, can be easily solved by definitively fixing the grinding wheel to the bench by means of bolts.

The only real problem with hobby bench wheels is the decrease in machine performance if more than what is required is required of it; exerting a lot of pressure on the wheels, in fact, you risk straining the motor, which responds with a drastic drop in the rotation speed.


The professional bench wheels

The professional models, on the other hand, do not suffer from this type of problem; they are made with first choice materials and assembled with care, so vibrations are drastically reduced and the performance of the engine is also characterized by greater consistency, even under stress, which is why they can withstand longer work sessions.

Their cost, however, is much higher and consequently their purchase is justified only in view of a professional, or in any case semi-professional, use of the machine; the same goes for the spare wheels and brushes, since it is necessary to take into account that these components wear out, and the speed with which they do so is directly dependent on the frequency and intensity of use.

The cheap ones, therefore, in addition to lasting less are also roughly ground and accentuate the vibrations of the machine during use, while those of higher quality do not have grinding defects but have an equally high cost.

How to assemble a bench wheel

The positioning of the machine

The grinder is essentially composed of an electric motor at the ends of which are mounted two grinding wheels, or a grinding wheel and a brush. Some specimens may further differ in that they are predisposed to the assembly of abrasive belts, or because one of the grinding wheels at the ends is mounted transversely instead of in axis with the one at the other end.

For reasons of mere convenience, therefore, it is advisable to first place the machine on the front edge of the workbench, even better if at one of the corners; in this way it will be easier to access the wheels and you will have greater freedom of movement.

Since the cheaper models tend to vibrate and move, it is also advisable to fix the grinding wheel to the bench using bolts; this operation is facilitated by the fact that these machines are already prepared for this type of assembly.


The crankcases and protections

Some elements of the bench wheel can be adjusted as needed. The protection screens, for example, can be inclined, while the support surfaces of the workpieces can be adjusted in extension.

However, these elements, although “mobile”, are still an integral part of the machine and must not be disassembled, unless it is necessary to replace them due to a possible breakage.

The guards that protect the wheels and brushes, on the other hand, are fixed by means of screws, so that they can be easily removed if necessary. The removal of the carters is required both in the case of replacement of the grinding wheels and when the machine needs to be cleaned and maintained; inside, in fact, dust and grinding residues tend to accumulate very quickly.

The assembly of the wheels and brushes

As for the grinding wheels and brushes, on the other hand, to proceed with their assembly you must first remove the relative protective casings, as previously mentioned. To replace the wheels it is best to refer to the specific procedure reported in the instruction manual, as this may change depending on the machine and manufacturer.


In addition, some replacement wheels are sold together with adapters, so that they are universally compatible with the specific size of the grinder shaft.

Before proceeding with the assembly of the grinding wheels and brushes, the machine must be rigorously switched off, and before switching it on subsequently, it is advisable to check that the joint of the grinding wheel has been correctly fitted, in order to avoid risks.

Frequent questions

What is the bench wheel used for?

The bench grinder, or more simply grinding wheel, is a stationary machine of more or less compact dimensions used for a wide range of applications, especially in mechanical workshops.

This electric tool, in fact, is used above all for the bevel of the edges on the pieces undergoing processing, in order to eliminate the processing burrs and cutting residues, to remove the chips that have remained partially attached and, in particular, to sharpen blades of various kinds. , cutting edges and bits for drills, milling machines, planers and thicknessers and other power tools.


By fitting the brass-plated steel brushes, on the other hand, it is possible to clean the metal surfaces by removing the rust deposits and encrustations that a normal brush is not able to eliminate; Furthermore, using special canvas discs, it is possible to smooth the steel until it is shiny like a mirror, or to polish the pieces of chromed metal.

According to the type of discs mounted, therefore, the type of processing changes, but essentially remains in the area of ​​grinding and polishing. In the hobby and artisan field, on the other hand, the bench grinding wheel, after assembling a reducer and a water tank, is used almost exclusively for sharpening the blades without running the risk of heating the blade and compromising the temper.

How much does a bench wheel cost?

The cost of a bench grinding wheel depends above all on its category, and the extent of the possible variations follows parameters that are different from those of other power tools.

The machines intended for hobby use, in fact, have a much wider range of prices on which not so much the technical characteristics, on which the performances depend, but the mechanical and structural ones affect.

The price for a hobby bench wheel can vary from around 30-35 euros, up to a maximum of around 100-150 euros. Those belonging to the professional category, on the other hand, start from a minimum of 150 euros and can reach very considerable figures, such as the bench grinders used for jewelry processing, which are around 2,000 euros, and the used vertical powder grinders. in certain laboratories, the cost of which can even reach 6,000 euros and more.

In the artisanal and semi-professional field, however, the cost is around 150 to 400 euros, depending on the model and characteristics. Both in the hobby, artisan and semi-professional fields, the most expensive models are those equipped with the reducer and the tray for using the water wheel, those designed for the use of abrasive belts and those capable of mounting discs. and brushes of different diameter and thickness.
