SDS drills can be used flexibly

A classic SDS drill is a quick-change system for drills. This system was developed by Bosch in 1975. The TE adapter developed by Hilti also emerged from this quick-change system. In many areas, the abbreviation SDS stood for a Special Direct System. Such SDS drills are usually used in hammer drills. They can be used for heavy applications in concrete and masonry. But what are the advantages of SDS drills?

Advantages of SDS drills

An SDS drill bit is equipped with a special SDS holder. It is mainly used for combination hammers and drill hammers. This is a drill equipped with a quick-change system. This is primarily intended for work in masonry, concrete or stone. The system is well suited for all hammer drills equipped with an appropriate SDS tool holder. If an SDS drill bit is to be purchased, a wide range of designs and sizes can be selected. Which drill bit is suitable for the particular job depends entirely on the intended use. But also the material to be machined and the required size are decisive when buying an SDS drill. The size of a drill always refers to its diameter. But the length of a tool can also play an important role. A distinction must be made between the total length and the working length. The working length always refers to the area of the drill where the spirals are used to remove the materials. The total length, on the other hand, results from the length of the shank and the working length.

Properties of SDS drills

SDS drills are often used for hammer drills. These are made of tungsten carbide The composition of additives such as cobalt or tungsten carbide is particularly decisive for the wear of a tool. By choosing a tool made of high-quality materials, the service life can be increased accordingly. The higher the concentration of the tungsten carbide material, the longer the tool life. It should therefore always be paid attention to a good quality when buying. It is better to reach a little deeper into your pocket when buying. Then with your SDS drill you can be sure that you can use your SDS drill for many years. The drills can be used with the aid of an SDS shank on the drill and combination hammers used in each case. Here the most different systems are available.

What are the differences between the different SDS systems?

The first SDS variant was developed by Bosch. This was introduced to the market as a further development of Hilti’s TE recording. Today, the system is often referred to as SDS-plus. This holder with a typical shank diameter of 10 mm is suitable for all hammer drills weighing less than 5 kg. The company Hilti uses the designation TE-C for the drills with such a recording. Later the name SDS plus was renamed to SDS-max by a further development. SDS-max holders can be used with a shank diameter of 18 mm, for example for heavy hammer drills of over 5 kg. At Hilti the SDS-max recording is called TE-Y. Less common are drills that can be used with a SDS-top or TE-T receptacle. These systems have a uniform shaft diameter of 14 mm. The SDS-quick system is only used for certain Bosch tools.

Can an SDS system still offer advantages?

SDS systems have two major advantages over other shafts, such as a cylindrical shank or a hexagonal shank. The biggest advantage is of course the simple and quick change of the required tools, which are made possible by the system. No additional tool is required to change an inserted tool, for example between a chisel and hammer drill. A second advantage is that a better power transmission is possible. With an SDS system, the locking of a drill bit in the drill chuck and the transmission of the torque can always take place separately. To this day, SDS tool holders from Bosch are still among the most popular systems. He has a wide range of manufacturers to choose from. Accordingly, a corresponding SDS recording can be found for many drills. In addition to Bosch, Makita and Metabo also offer many SDS drills.

Application areas of SDS systems

Masonry and natural stone are often built with a carbide-tipped masonry drill. Especially carbide-tipped drills with a diameter of up to 52 millimeters are perfectly suited for concrete walls. In most cases, the tip of a masonry drill has an angle of 120 degrees. With a special concrete drill, the front tips have an angle of up to 130 degrees. For many concrete drillings, however, drilling attachments can also be used, which are often used in the area of stone walls. With pneumatic hammer drills, the special feature of an SDS plus mount is that the tool change is even faster and easier. Everything from stone to hard concrete walls can be easily drilled through.

Simple

handling

Behind the term SDS drill hides the most different meanings for the same system. This term refers mainly to drills that can be used specifically for drill shank systems. Actually, the name comes from the Bosch company. The company specialises in the manufacture of various tools and handicraft equipment. Bosch has made a good name for itself on the market thanks to the good quality of its products. The company has used this term to describe its plug-and-turn seat drill. No matter whether SDS, SDS-plus or Special Direct System – all systems offer the advantage that they have proven to be extremely practical. The drills are equipped with special grooves on the shank. These snap into a drill chuck. Thus they provide for an optimal hold. At the same time, the systems enable excellent power transmission. Compared to other plug-in systems, SDS drills do not require any additional tools. Drilling keys for clamping and unclamping can be safely put aside. You simply have to clamp the drill bit into the tool provided. After that you should check the engagement and you can start your work. The drill head must be pulled back a little when clamping. This causes the locking device to engage in the grooves and release them. A drill bit can therefore be easily removed from the machine. Depending on the device, there are some small differences in handling. The actual principle of an SDS drill, however, remains the same for all models.

Work like a professional

If you decide to buy an SDS drill, then you can’t do much wrong. With an optimal fit, perfect work is possible at any time. With conventional clamping drill heads, you can also clamp the drill slightly angled. This has the advantage that the SDS The drill is always centered in the drill head. The result is that you can work reliably and precisely like a professional. Also the simple and fast change between the different sizes is no longer a big problem. The change can be carried out at any time so that not much working time is lost. Of course, before you buy an SDS drill, you always have to make sure that your machine is equipped for it. If you buy a new drill, you should also make sure that the drill or drill collar is compatible with the SDS system.

Special features of an SDS socket

A TE drill bit is always subject to high wear. Especially at the edges where the grooves are located, the material often frays strongly. Accordingly, replacements must often be made in this area. The wear and tear of the material also affects the transmission of the force in particular. Through the invention of the SDS shank, an innovative workpiece was created that has helped to achieve a more precise drilling result in recent years. The system is not only found in drilling machines, but also in many hammer drills. The SDS plus system has not been patented for a long time. This system is therefore offered not only by Bosch but also by many other drilling machine manufacturers. Hilti in particular expressed great interest in this SDS drill system and offers a variety of different tools.

The most popular SDS drills

One of the popular systems is the Bosch Pro Hammer Drill Set SDS Plus 5. This set is suitable for all hammer drills with an SDS plus receptacle. The tool is made of a durable tungsten carbide and has a long service life. It is very resistant and can be used for many years. In addition, it is equipped with a clearly visible wear indicator. Another good offer is Makita. The SDS-plus Drill & Chisel Set D-19180 also has a good quality. This is a 17-piece set that is delivered in a robust aluminium case. In addition to the 12 drills, the case contains a pointed chisel, a flat chisel and a wide chisel. The hammer drill set is very suitable for concrete, stone, granite and other harder materials. As an alternative, the S&R professional can also be used. hammer drill can be used. This model is also a multipart set. This set consists of 7 parts and has a good price / performance ratio. The SDS drill is usually used for masonry, natural stone or concrete. At the same time, the device has a so-called destruction effect. This is made possible above all by reinforced destruction teeth, which connect at the tips. This allows micro cracks to be created in a drilling material. This has the advantage that a noticeably improved drilling speed is available.
