Rating of the best rock drill drills for 2024

Every person has a period when major repairs begin. And it won't end with just a wallpaper change. Such an event involves destruction, drilling, creating 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 working process to proceed easily and without interruption, you should carefully consider the choice of equipment for the hammer drill. Many people mistakenly assume that conventional drills can be dispensed with. But, not 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 drill

This unit is one of the main types of equipment for a hammer drill, 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 hammer drill. The drills are stable during drilling thanks to the rounded tip. Carbide is used to create the cutting part, and the main part is made of torsion-resistant metal.

The drill is not designed to handle fragile materials. In work, it makes a shock and a turn, so it is used for drilling such hard materials as concrete, brick or stone, as well as for working with hard wood, where a conventional drill cannot be used. Before starting operation, a special lubricant should be applied to the drill shank, and then fix it 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 the drill is drilling. Although there are devices that have a punch function, this is already in addition to drilling. And in the hammer drill, on the contrary, in the first place is the function of impact and crushing of the material, which is supplemented by the possibility of rotation. The rigs for the two tools are similar in appearance, but they can be used interchangeably. This is due to the fact that the drill in the hammer drill has a non-rigid mount for quick tool change. And the drill has a jaw chuck, here a rigid mount occurs.

Now let's look at the differences in design between the two tools. The drill shank is a smooth surface with a simple shape. And the shank of the drill is in the form of a cylinder with projections and notches, which are called SDS-plus and SDS-max. Drill flutes have a sharp edge, with their help they cut holes in the workpiece. This design is designed for rock drill rigs to remove material residues. The drills also differ in their design for the purpose of a particular material.For example, drills for metal have a different angle of sharpening of the head, and for working with wood, the tool has a self-centering head.

Drill types

This product differs in design features. By the appearance 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 its length is about 40 mm, and there are also 4 recesses for installation in the cartridge. And the diameter of the product itself can vary from 4 to 26 mm, they are used for household rotary hammers. Drills with a diameter of more than 26 mm have a shank with the SDS-max marking. The diameter of this shank is 18 mm and its length is 90 mm. They are used in high power tools. SDS-top drills have a 14 mm shank diameter and a 70 mm length. they are rarely used. There is also SDS-quick, which has keys and a holder.

This equipment also differs in the shape of the working part. The screw unit has a large angle of inclination of the groove, due to which a deep hole of various diameters can be obtained. It has a spiral device, and during operation it creates a high rotation, thanks to which dirt and dust are quickly removed, operating time is reduced, and the hammer drill does not receive a large load. If a deep hole is not required, then a tool with a small tilt angle is used. When a large number of deep holes are required, a drill with a large angle of inclination of the grooves is used. They create a high drilling speed and excellent dust extraction. But this type creates a large load on the tool, so a powerful hammer drill is needed to work with it.

In addition, you can classify the tooling by the type of soldering. The classic option is carbide brazing, where the cutting edges are located in the form of a cross. There are also centering solders. They have a special geometric shape, during operation the drill will not "go away" from the center.

The rig 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 hammer drill

Arriving at a hardware store, the buyer will be faced with the abundance of products on offer. It will not be difficult for a professional to choose a suitable unit, but a beginner may have difficulties. Today there are more than 10 official manufacturers of rock drill rigs in the world. But still, along with this, there are many fakes of products from popular manufacturers, or poor quality goods that will not satisfy your needs.

First and foremost, you need to decide on the type of shank that will fit your tool. Heavy duty rock drills that primarily use SDS-max shanks have adapters. The adapter can be used to mount 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 purposes. For working with concrete, a diamond-coated tip is suitable. Such a product is distinguished by its reliability and high performance. Victory 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 instrument will quickly become blunt. And the version with a centering spike can be self-sharpening during operation, as well as its edges have cutting edges, which will facilitate the work process. Also, the element installed in the hole made by the 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 deteriorate. 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 value. But their reliability, durability and convenient operation will easily justify their price. If the product is needed to make several holes in the wall, then you can take a cheaper unit, which you do not mind throwing away later.

Drill care

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

So, in the process of drilling, you do not need to put all your weight on the perforator, 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 breakdown. 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 it not with one drill, but start with a smaller size and gradually increase the size. Shank lubrication is sufficient for 1000 holes. Before relubrication, everything should be well cleaned of dust, and only then apply new grease. When there is a large amount of work to be done, it is necessary to give the instrument periodic rest. At this time, the drill is placed in water or machine oil, and the drill needs to be disconnected from the mains.
