To produce a hole; a solid carbide drill bit has to remove a large volume of material. By comparison, Tenn rotary hammer core hits get the job done more quickly and economically as they need only cut along the periphery to make a hole. This makes it possible to drill large diameter with small handheld rotary hammers, thus saving on tool costs.

Tenn Rotary Hammer Core Bits are distinguished by their thin-walled core bodies which are light in weight but are durable and strong. Special chisel geometry on their randomly spaced carbide teeth gives fast penetration rates and long service life.

Bit life up to 250 holes in brickwork or non-reinforced concrete.
