Shopping guide

In the next section, you will find a guide to buying the best drill bits, where we will detail the most important characteristics that you should take into account, so that you can choose a good and economic drill bit.

 
Bit type

When working with metals, it is important to evaluate the type of bit because they have a much greater hardness than other materials, which means that there is a difference in the way they work with a different type of surface such as wood, steel, plastic or glass.

There are different types of drill bits to choose from when it comes to the drills for woodworking. They can come in either a spiral shape or a circular tip with a hole in the middle, which is known as a Forstner bit.

When drilling into glass, glass, ceramic, porcelain, tile, and tile, there is a similarity to wood, but the tip is very sharp. The pieces of diamonds that help to make the cutting process as delicate and efficient as possible with little chance of damage to the structure are included in some diamond models.

The function of the pieces of diamonds being used in hammer drills is due to their resistance being greater than that of the conventional type, which makes them ideal for intense work.

Size and diameter

Although it is not always necessary to use the same size of bits, it is a good idea to buy the ones that correspond to your desired hole.

If you are going to drill a hole with a bit that is a fraction of a centimeter, make sure that it has a diameter of at least half a millimeter.

One thing to remember is that the size of the hole will be smaller than the diameter of the bit, however, the step of the drill must be based on the height of the bit.

If you have a 10mm bit, you must use a 12-step drill, but remember that the hole will be much smaller than the bit, and therefore, you will need to make sure that the string is taut when you use it. By using a drill with multiple bits, users who need to make different sizes of holes in wood or metal will be able to do it in less time, because the working time will be much less.

 
Materials

The material of manufacture, the price and the protection against rust are some of the factors that should be considered when purchasing a drill.

The most recommended drills are made out of titanium, titanium dioxide, and other materials that are resistant to rust and have high degrees of hardness.

If the drill bit has the initials HSS or it is rectified, it means it has high speed steel in its composition or it is combined with other materials which makes the drill bit more effective. A good quality drill bit is in demand when it comes to efficiency.

Frequently asked questions

Q1: How to use a drill bit?

Since there are special bits for each type of material and if they are not used correctly, they can break in the process and even damage what you are drilling, you have to identify what material you are going to work with.

You have to consider that you have to work the drill at a specific speed so that the bit doesn’t suffer damage, after selecting the bit. In other words, make use of low revolutions for hard metals and higher for softer metals, wood, plastic and other fragile structures.

If you want your bits to last as long as possible, we recommend that you clean them after use with a dry cloth, and then apply a metal cleaner. To avoid harming the protective layer, check that it doesn’t have any bleach or chlorine.

Q2: How to sharpen a drill bit?

If you want to cut the grinder correctly, you need a grinder with a rough pumice stone or wheel, gloves, and goggles to protect your eyes. The grinder needs to be fixed so that it doesn’t move while you are using it. If you want to get rid of the damaged part of the bit, you have to tap it evenly and horizontally.

You will have to make the bit have a 30 drop on both sides, because it will allow it to rotate evenly. To do this, place it in a diagonal position and immediately make the degrees of fall by making a small movement of the bit upwards.

If you do the same with the other face, make sure that they are both the same and respectful of the axis, since it must be parallel to the diameter.

Q3: How are steel drill bits made?

This begins as a metal rod that is later placed in a machine that is responsible for making the cone-shaped tip, and then it goes on to another machine that is responsible for making spiral grooves. At the end of a series of bits, all of them are coated with titanium to give them protection and greater resistance.

Q4: Why are the measurements of the bits expressed in fractions?

To be able to approximate the result to be drilled for each drill, the results are expressed in fractions. The selection of one that is as close to the hole you want to obtain is made possible by the fact that the fractions are divided to get a decimal number.

Q5: How to differentiate the drill bits?

There are two spiral-shaped channels in the drill bits that are for metals. On the other hand, those that are for wood have 3 sharp points, where one of them, specifically the one in the middle, works as a drilling guide. The ability to drill from stones to bricks is improved with those that are used for concrete that have a head at the tip.
