The best drills for a hammer drill: types and their features

A drill for a hammer drill is a special-purpose equipment that allows you to punch holes of different depths and different diameters.

Concrete drills differ in the material and shape of the cutting edge, the design of the shank, the number of gutters for removing debris and other parameters.

What features of hammer drills should you pay attention to when choosing which sets of equipment are the best today, we will consider in this review.

PROJAHN 8303110 Drill SDS PLUS – the best in its segment

Designed to create holes in concrete, including reinforced concrete. Equipped with a fixation system in the SDS+ rotary hammer for quick change of equipment. Penetration into a durable concrete layer is facilitated by a composite carbide tip. Accurate soldering centering will ensure that the hole is made with the required tolerances for deviation from the specified dimensions.

Pros:

• Strength.
• Plunge speed.

Minuses:

• Overcharge.

Bur: purpose

Drills and drills are consumables, but their importance in the design is high. The element is a impact-cutting element. Novice builders sometimes confuse this product with a drill, but there is a big difference between the two.

The drill is made from alloy steel, but also has diamond brazing. This solution will increase service life and wear resistance. It has a tail part where special grooves are located, a spiral rod and a cutting part. Just like a drill, it is installed in a hammer drill chuck. We must not forget that the drill is a consumable item and is often used to create holes in a concrete or stone wall. The product should not be used on metals or wood as it is not intended for this purpose. For such purposes, it is worth purchasing the appropriate tools.

Drills are sold in different lengths and diameters. If a person is looking for an option for use at home, then a good solution is 6-10 mm. In this case, it is necessary to select a dowel that is suitable for these sizes. The maximum diameter is 5 cm. In the professional sphere, builders use material with a length of from 10 to 100 cm. It is important to understand that when making technical holes, compliance with the diameter and length is a mandatory requirement. This is the only way a person will ensure the greatest efficiency and durability of the nozzle.

A drill is not a drill

In terms of external signs, these elements have a minimum of differences, which is why an ignorant person may get confused and buy the wrong option. In addition, their purpose is also the same - creating holes. The only difference is that the drill is designed to work with plastic, wood and metal, but the drill is used only for concrete or brick surfaces. Often, because of this ignorance, people buy a standard drill, and when they get home they immediately break it.

The drill is many times stronger than a conventional element, and also has a larger size and diameter. The maximum cross-sectional value of the drill is 14 mm; for impact-cutting products this figure reaches 55 mm. In addition, the design of the shank differs. So the drill has special grooves, while the drill does not.

The product is used in every hammer drill, even hammerless ones, but it is not intended for use in a drill. Some drill models are manufactured with multiple cutting inserts and may also have a special geometry that holds it securely in the center of the hole. Also, impact cutting tools are durable, but the price of this product is several times higher.

What to pay attention to

There are hundreds of attachments in the store, and it can be difficult to determine exactly which one is suitable for a particular situation. Sometimes it takes several minutes to find a drill, especially if there is no consultant on the sales floor. To quickly identify a tool, just look at the shape of the edge that is fixed in the chuck.

The product has a cross-section with a complex configuration, so it can be with a small groove, convexity, SDS, etc. Unlike a drill, a drill has a standard round shape.

A complex cross-section is necessary for this tool, as it guarantees a tighter connection with the chuck of the electric tool. All attachments are classified into different categories to make it easier for a person to find a specific model. However, despite all this diversity, two types are considered popular:

Concrete drill (5x50/110 mm) SPEC-0210002 – optimal for domestic purposes

What is a drill

A standard drill consists of several parts:

• shank - an element designed to attach a drill to a hammer drill chuck. It has several varieties and is located at the back of the device;
• spiral;
• core;
• cavity for dust removal - a special groove with the help of which the tool itself is cleaned of construction debris;
• carbide cutting plate - the tip of the device with which the work is carried out.

Types of drills

Like most similar tools, the drill is not available in only one form; there are hundreds of variations in the store. Some are designed for concrete, while others are for dismantling. Depending on the design, the scope of application is determined.

Screw

This is a self-sharpening element that is used only when drilling deep holes. It is able to work for a long period and not break, while the quality of the grooves made is at a high level, no defects or cracks are formed. The durability of an auger drill is tens of months.

Often this element is used to create cylindrical holes. To create a groove of a larger diameter, it is necessary to use a pick, which functions on the principle of an electric hammer.

For dismantling and installation

Such models are designed for dismantling and work with many materials. To install electrical sockets, you need to use a part in the form of a crown. Using such a drill, a person will receive a high-quality hole of the correct shape, which will make it easy to place the necessary elements. This type is used for organizing water supply, as it is able to create the required diameter for laying pipes

For wood and earth

For wood, you can use not only a special drill, but also a drill, the latter will be many times superior to the element in terms of technical indicators and processing quality. Using such a tool, the working force will be reduced, and the chips will be separated quickly.

An earth drill is used to create round and neat holes. Thanks to the special structure of this device, a person will be able to create a hole of the required depth with minimal effort.

Concrete drill SDS-plus S4 (8x50/110 mm) Kraton - cheap

Successfully drills concrete, brick, rocks. The rod is made of the same diameter along the entire length, which increases the overall strength. Indispensable for drilling holes for kitchen and clothing wall cabinets, for hanging heavy mirrors and shelves.

Pros:

• Lowest price in its segment.
• Withstands the stress of home renovations.

Minuses:

• It begins to rust when the ambient humidity is high.

General recommendations

In order for the part to serve the maximum period and not break at the wrong time, it is recommended to frequently lubricate moving parts. To accomplish this, gel substances (for example, products from ARSENAL) or in the form of a spray (for example, WD40) are suitable. In addition, the protective layer that is applied to the outer surface will prevent the corrosion process.

If a person plans to use a drill when carrying out home repairs, then it is not advisable to buy expensive equipment, since its potential will never be revealed.

Products from the domestic segment will become affordable elements with high reliability. If you treat such drills with care (lubricate, do not overload, clean), then their service life will double.

Concrete drill (8x50/110 mm; SDS+) SPEC-0210004 – good service life

The equipment is designed and used to work with power tools equipped with the SDS+ fixation system. The destruction of concrete, brick structures or mining materials is carried out by a tip made of a composite tungsten carbide alloy. Compliance with assembly technology made it possible to increase the service life of the equipment.

Fixation in the chuck

The most basic thing you need to understand when buying a drill is the types of shanks. After all, inexperienced craftsmen have situations when, after purchasing a drill, it turns out that it does not even fit the tool. You have to go back to the store and exchange for another one.

For a better understanding, let’s look at each type of SDS system[1]:

SDS-plus - most household hammer drills are equipped with this chuck. This type is intended for shanks of the same name, the diameter of which does not exceed 18 mm. The tool is securely fixed thanks to 4 grooves, two of which are responsible for locking the drill in the chuck, and the other two set the exact direction of movement during impact impulses.

SDS-top has almost no differences from the pluses, but it performs better when drilling holes larger than 16 mm. The drill is fixed in a similar way, but lies deeper into the tool, which increases the contact area. This cartridge almost always comes with a smaller plus version.

SDS-max is designed for more serious tasks. However, such a cartridge is found only in professional series of hammer drills and is rarely used in everyday life. A drill for such a tool can exceed 18 mm in shank diameter. The structure of such a shank is similar to SDS+, but has additional grooves for energy transmission.

SDS-quick is only used in some Bosch rotary hammers. This chuck is considered universal and is capable of fixing hex bits and drills, in addition to drills. However, it is intended for small diameters and is used only in everyday life.

There is also a cam adapter for the hammer drill . It allows you to use a hammer drill, which has a drilling mode without impact, with cylindrical drills and even bits for screws. This chuck is useful when you don’t have a drill at hand, but there is an urgent need to drill a hole in wood, metal, etc.

[1] S pecial D irect S ystem - “special guide system.” Invented and created by Bosch to make it easier to remove tools from the chuck.
