Rating of the best hammer drills for 2022

Every person has a period when a major overhaul begins. And it won't just end with a change of wallpaper. Such an event involves destruction, drilling, the creation of new holes and many other building "fun". And the main assistant in this matter will be a puncher. After all, this tool combines the qualities of an impact drill and a jackhammer. And in order for the workflow to proceed easily and without interruption, you should carefully consider the choice of equipment for the puncher. Many mistakenly assume that conventional drills can be dispensed with. But, without having time to start the process, this element will quickly become unusable. Unable to withstand the load, such drills instantly become blunt and bend.

What is a bur

This unit is one of the main types of equipment for a puncher, which looks like a drill. In its design, the drill has a shank and a spiral, with the help of which the destroyed material is removed. Using the shank, the tool is installed in the punch. During drilling, the drills show stability due to the rounded tip. To create the cutting part, a hard alloy is used, and the main part is made of torsion-resistant metal.

The drill is not designed to interact with fragile materials. It punches and twists as it works, so it is used for drilling in hard materials such as concrete, brick or stone, as well as for working in hard woods where a conventional drill cannot be used. Before starting operation, a special lubricant should be applied to the drill shank, and then it should be fixed in the chuck. This increases power and reduces losses.

Drill and drill. What is the difference?

A drill is a tool that is a tool for a drill. The main purpose of a drill is drilling. Although there are devices that have an impact function, this comes in addition to drilling. And in the perforator, on the contrary, in the first place is the function of impact and crushing of the material, which is complemented by the possibility of rotation. The rigs for these two tools are superficially similar, but they can be interchanged. This is due to the fact that the drill in the perforator has a non-rigid mount for a quick change of equipment. And the drill has a cam chuck, here there is a rigid mount.

Now let's look at the differences in the design of these two tools. The drill shank is a smooth surface with a simple shape. And the drill shank has the shape of a cylinder with protrusions and recesses, which is called SDS-plus and SDS-max. The flutes of the drill have a sharp edge, with their help they cut holes in the material being processed. This design for perforating equipment is designed to remove material residues. Also, drills differ in their design as intended for a particular material. For example, drills for metal have a different sharpening angle of the head, and for working with wood, the tool has a self-centering head.

Types of Boers

This product differs in design features. According to the type of their shank, tools can be divided into 4 types. The most popular is the drill with the SDS-plus shank marking. Its diameter is 1 cm, and the length is about 40 mm, and there are also 4 recesses for installation in a cartridge. And the diameter of the product itself can vary from 4 to 26 mm, they are used for household punchers. Drills with a diameter of more than 26 mm have a shank marked SDS-max. The diameter of such a shank is 18 mm, and its length is 90 mm. They are used in high power tools. Drills marked SDS-top have a shank diameter of 14 mm and a shank length of 70 mm. they are rarely used. There is also an SDS-quick, which has keys and a holder.

Also, this equipment differs in the shape of the working part. The screw assembly has a large angle of inclination of the groove, due to this, it is possible to obtain a deep hole of various diameters.It has a spiral device, and during operation it creates a high rotation, thanks to which dirt and dust are quickly removed, the operating time is reduced, and the hammer does not receive a large load. If a hole of great depth is not required, then a tool with a small angle of inclination is used. When drilling a large number of deep holes is required, a drill with a large flute angle is used. They create a high drilling speed and perfectly remove dust. But this type creates a large load on the tool, so a powerful puncher is needed to work with it.

In addition, equipment can be classified according to the type of soldering. The classic option is carbide soldering, where the cutting edges are arranged in the form of a cross. There are also centering soldering. They have a special geometric shape; during operation, the drill will not “leave” from the center.

Equipment is also divided by size. The total length can vary from 10 to 100 cm, the length of the product will depend on its diameter. And the outer diameter of the drill depends on the type of shank.

How to choose a drill for a perforator

Arriving at a hardware store, the buyer will be faced with an abundance of products on offer. It will not be difficult for a professional to choose a suitable unit, but for a beginner it may be difficult. To date, there are more than 10 official manufacturers of punch tooling in the world. But still, along with this, there are many fakes of products from popular manufacturers, or low-quality goods that will not satisfy your needs.

First of all, you should decide on the type of shank that will fit your tool. Powerful rotary hammers that mainly use SDS-max shanks have adapters.Using an adapter, you can install a unit with a different shank. Having decided on the shanks, you should choose the size of the drill itself. Here everything will depend on what material the product is purchased for and your goals. For working with concrete, a diamond-coated tip is suitable. This product is known for its reliability and high performance. Pobedite tips will be optimal for working with brick or stone.

Also pay attention to the shape of the cutting surface. If the product has a straight surface or there is a small protrusion on it, then during operation there will be a large load on the hands of the master, on the device itself, and the tool will quickly become dull. And the version with a centering spike can be self-sharpened during operation, as well as its edges have cutting edges, which will facilitate the work process. Also, an element installed in a hole made by a centering drill will hold better.

If we talk about durability, then it will be cheaper to choose a more expensive, but high-quality option. Having a large amount of work, a cheap product will quickly become worthless. This parameter will be influenced by the material from which the unit is made, as well as the material of the tip itself.

Also, do not forget to look at the company that produces these units. Famous brands have a higher cost. But their reliability, durability and convenient operation will easily justify their price. If the product is necessary to make several holes in the wall, then you can take a cheaper unit, which you don’t mind throwing away later.

Drill Care

Each product has its own resource. But with proper care and maintenance, it can be easily extended. And improper use can lead to early tool failure.

So, in the process of drilling, you do not need to lean on the punch with all your weight, this will not increase the speed of its work. The tool must not be allowed to idle. In this case, there will be absorption of its own energy, which will lead to early failure. For very hard surfaces, a special lubricant should be used, as well as periodic cooling with a liquid. The product passport usually indicates the recommended lubricant and manufacturer, but if it is not possible to purchase the specified brand, a similar replacement is allowed. Also, if you need to make deep holes, then it is better to do this not with one drill, but start with a smaller size and gradually increase the size. Shank lubrication is sufficient for 1000 holes. Before a new lubricant, everything should be well cleaned of dust, and only after that apply a new lubricant. When there is a large amount of work to be done, it is necessary to give the tool a periodic rest. At this time, the drill is placed in water or engine oil, and the hammer must be disconnected from the network.
