Countersink

The HSS Countersink Bit, cylindrical shank performs smooth countersinking for screws and deburring of holes in tough materials. The ground countersink is made of HSS (high-speed steel) and offers an optimum surface quality for easy work on tough materials. Three 90-degree cutting edges that continuously work chattering- and burr-free provide excellent results while slicing through solid surfaces. The HSS Countersink Bit is manufactured to DIN 335. The best results can be achieved when working at a low cutting speed.
