Cutting edges Type and applications overview

Main application Other application Non-ferrous metals Concrete reinforcement Lightweight material

A special drill dust groove geometry ensures optimum drill dust feed. Reduced vibrations and low friction result in significantly shorter drilling times. Core reinforcement for maximum energy transfer. No risk of breakage when hitting reinforcement. Areas of application: for granite, concrete, clinker, stone, masonry and marble. Packaging: self-service clip or QuadroPack

SDS-plus hammer drill with 2 cutting edges Longer service life in concrete and on reinforcement thanks to stabilised head geometry and rounded cutting edges. Patented 2-edge design based on the Bionic principle. Innovative Twinmax 3D helix profile enables optimum drill dust transport. Certified by the Prufgemeinschaft Mauerbohrer (PGM) in accordance with the requirements of the Deutsches Institut fur Bautechnik (DiBt). Areas of application: For granite, concrete, concrete reinforcement, clinker, stone, masonry and marble. Use: In all rotary hammers with SDS-plus chuck and 2-slot chuck, e.g. Hilti...

Packaging: plastic tube

High time of exposure is guaranteed by a special alloyed steel quality. For precise center drilling on hard surfaces. Ideal for non splittering and precise drilling. Special tungsten carbide plate with center point. Applications: for drilling in tiles, clinker, stone, masonry, plastics, non-ferrous metals, soft and hard wood and lightweight material. Only usable for revolving application in turning and impact drilling machines. Ideal for accumulator machines.

Hammer percussion drills with carbide cutting edges High performance due to very stable and thin-walled core bit body. Areas of application: for concrete, stone, masonry and brick.
