Holle kern bit voor zeskant adapter

The SDS plus-9 CoreCutter is ideal for cutting holes, especially 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 when drilling for switch box installation. The bit is intended for use in concrete, masonry and limestone.
