The SDS max-9 CoreCutter is ideal for cutting deep holes when installing switch boxes. It is made with fine-grade, highly durable carbide that ensures the best wear resistance when drilling. Furthermore, the number of the asymmetric carbide teeth on the bit are adapted to its diameter, making it the right choice for aggressive work progress with quiet operation. Its long 2-flute U-shape shank is good for dust removal and breakthrough-drilling while its one-piece design guarantees optimum transfer of the machine's power. The bit is intended for use in concrete, masonry and limestone. It is compatible with SDS max drills.
