Powers® Tri-Cutter™ SDS-Max® carbide drill bits are designed for use in a rotary hammer equipped with an SDS-Max® type chuck. The bits are manufactured to conform to ANSI Standard B212.14 and can be used to drill in concrete, block, brick, and soft stone. The Tri-Cutter™ head design has three main cutters in a “Y” configuration, which made up to 32% less noise and vibration compared with the "X" cutting head.
