The masonry drill has a non-cutting shaped drilling helix, which is also suitable for rotating application into concrete. The material strength is adapted to drill shanks and shaft diameters. Therefore it is appropriate for rotating as well as for percussive application.
Percussion drill bit KEILER
The percussion drill bit KEILER differs from other stone or percussion drill bits because it is manufactured from high quality chromenickel-molybdenum steel. It has a wear resistant carbide plate which is fixed with the drill bit body by high-temperature brazing at 1,120° C.
Furthermore all KEILER drill bits have a straight flute exit and a reinforced drill bit head as well as the approved S-flute shape, which provides with its milled helix an optimum removal of drilling dust and clean holes.
