Sandblasted concrete drill bits with diamond-ground carbide tips — metric and inch ranges in one series. The full matrix covers metric sizes from 3 mm to 26 mm and inch sizes from 1/8" to 1", plus 5-piece and 8-piece set cards, for anchors, fixings and through-holes in concrete, block and brick. Factory-direct from a 20-year precision-tools manufacturer with ISO 9001 / 14001 / 45001 triple-system certification.
Diamond ground percussion carbide tip with two cutting edges.
For drilling in brick, soft ceramic tile, plaster and aerated concrete blocks.
From Ø13 mm the drill bits are supplied with a multi-flat shank to prevent the drill bits slipping in the chuck.
