Different Types of Drills in the Market


Today we will talk a bit about the most common drills and try to keep the article as simple as possible, in future posts we will go into more detail.

The first thing you should know before buying a drill bit is the material you want to drill, is it steel? or maybe wood? maybe it is concrete if you know the material we are on the right track! because for each of these materials there are specific drills, if we use a drill bit other than the one indicated for the material to be drilled, it is most likely not to work and break.

Then once we know the material we have to ask another question, what is the diameter of the hole we are going to make? the drills sell them for specific materials and diameters, the most common diameters vary between 4mm and 10mm but now it is not the most common thing but what you need so you must know the desired diameter.

We already know the material and the diameter? very well !, but how do we know at a glance to differentiate between wood drill, steel drill (HSS) and concrete drill (walls)?

Wood Drill:

It is the easiest to differentiate, it has 3 pointed tips on the head, the middle tip is what makes it clearly different from the concrete drill bit or concrete drill bit. The central point acts as a guide for drilling in wood and all its derivatives.

Concrete drill:

These drills are used to drill bricks, stones, concrete, etc. In the head, they have a reinforcement that gives them a form of "shovel" since it is reinforced with a material of great hardness to increase the duration of the same and guarantee its capacity of perforation.

Metal Drill or Fast Steel Drill Bit (HSS):

The quick-drill bit allows drilling in virtually any metal, whether iron, cast iron, aluminum, brass, steel, etc.) The tip, unlike the concrete drill bit and wood drill bit, has a tapering tapered end and features 2 helical channels, the smaller the hole to make these drills must rotate at greater speed.

As we mentioned at the beginning of the article you can go much deeper into the subject because there is a world inside the drills such as the HSS-CO drill which is a steel drill with cobalt alloy for a better result, but the idea is to convey a basic knowledge for those who start in the DIY world.

Learn to choose the right drill

For home or industrial uses, a wide variety of drills are available for all types of Black and Decker drills of all sizes, shapes, and materials, each with a specific function and different working and operating conditions.

However, for many people, all drills may look the same, and their only purpose is to quickly open holes in the wall; however, each of them is designed to act in certain situations and perforate different materials. This is a guide to replace that multi-purpose drill bit in your toolbox and start using the indicated ones, depending on the material for which they were designed.

-The stone drill: also used for drilling of brick and concrete, this is the most common drill bit for all kinds of home and construction work. This is characterized in that at its tip can be highlighted a blade or wick finish, which is breaking the material as it drills, while the propellers of it expel the dust, then facilitating the use of screws and nails on the wall, in the set with a set of Stanley screwdrivers and hammers.

Inside this type of tools for construction, you will find drills for concrete and for ceramics. The former is made of a more resistant material, and a harder metal, in order to drill more complicated materials. In the case of the latter, they usually come with a diamond coating, ideal for piercing slabs without breaking them.

-Bank for metal: The accessories for drilling this are characterized by having a sharper tip, in addition to being very light. They are often darker in color and are made of steel, for softer metals such as copper and aluminum, or cobalt, vanadium or titanium carbon alloys for harder materials.

-Boats for wood: These are characterized by their unique shape, unlike other drills, which is composed of a trident at the tip, which is sharpened to be able to drill the wood properly and in the exact point that marks with its tools of measurement, in addition to preventing it from moving during work. Its other defining characteristic is the silver-tone mixed with dark gray.

-Brokes for glass: Much like ceramic drills, these are designed in order not to pierce this delicate material. In addition, the drill must rotate at low speeds to accomplish this task.

-Brass Universal: They are designed to be used in a lot of materials, and are ideal for those who only need a drill for all their household tasks. They should be used without percussion, so that this cut and pierce the material instead of breaking it like others. They can also be used in all kinds of drills.

Finally, as there are different uses of abrasive discs and saws for all tasks, the thickness and size of these vary according to the work in which it will be used. These will come between 1mm in diameter, for precise jobs, and 25 for larger tasks. The length of this will also determine the depth of the holes you make.

World of Screws recommends you to nail drills, open holes or install furniture or shelves, that you will never miss the 4- to 10-mm drills in your toolbox, as they will do all these tasks. Of course, consider the material you will drill.
