Bosch FORSÆNKER 1/4/16MM/HSS

HSS countersink drill head with hexagonal shaft creates smooth countersinks for screws and deburring of holes in hard materials. The ground countersink drill head made of HSS (high-speed steel) has an optimal surface quality for even work. Outstanding results in hard materials are possible thanks to three 90-degree cutting edges that function continuously, without vibrations or burrs. High power transmission thanks to the hexagonal shaft provides a flat hole sink. It is suitable for use on non-ferrous metals, steel, and cast iron and has a hexagonal shaft system for versatile use. The HSS countersink drill head with hexagonal shank is manufactured according to DIN 335. The best result is achieved by working at low cutting speeds. It can also be used with impact wrenches
