Ideally suited for tiles up to scratch hardness 6, ceramics, marble, Eternit, aerated concrete, vertically perforated brick, light-weight building material, plastics, coated plates, soft steel, casting and even reinforcing steel in concrete as far as building stability allows
Heat-treated special steel - long service life for the use with most different materials
Specially soldered carbide cutting edge with stress-relieved soldering technique at more than +1100°C reduces break out or annealing of carbide cutting edge
Diamond ground sintered cutting edge makes immediated centering on hard surfaces possible
Special cutting angle optimizes the drilling from the beginning
AGR 5604:
With cylindrical shaft, also ideal for the use with drilling machines
