Special concrete & stone drill bits are used for drilling in concrete and masonry. It is important to use drill bits from certified manufacturing to ensure correct installation of components. Drilling tolerances may be exceeded if the drill used is not from a monitored production facility. Drills that are too far out of round, or with excessive tolerances in the carbide cutting edge can lead to drill holes that do not give a plug sufficient hold. In extreme cases installed elements will come loose and cause significant damage.

Having the right equipment for metalworking keeps your business competitive in your sector. With Kennametal inserts, you have access to the correct performance inserts for milling and cutting, including both positive and negative inserts. Our high-performance inserts give you precise and low-vibration cutting, allowing you to achieve true and consistent results every time.

In terms of concrete drill bits, we even recommend using products produced as per the regulations of the Masonry Drill Bit Testing Association (PGM), an independent institute. You can identify these bits by the quality mark or the symbol embossed onto the drill bit. Heller exclusively uses the best steel and tungsten carbide plates for its concrete and masonry drill bits. At the same time, accurate processing is paramount, for instance as a result of the precise alignment and soldering of carbide plates or a strict concentricity tolerance. Finally, aspects, such as ergonomics and occupational safety are paramount. In this process, we aim at meeting professional users’ demands. After all, all Heller products contribute to faster and more economical working for professionals.
