2608597503 - Conical countersink 20.5, M 10, 41 mm, 1/4

The HSS countersink with hexagonal shank enables fast countersinking of screws and deburring of holes in metal. The ground countersink made of high-speed steel (HSS) is characterised by an optimised surface quality for uniform processing. The three 90-degree cutting edges ensure excellent results, which drill without producing vibrations and burrs. The high power transfer, made possible by the hexagonal shank, enables a flush countersink of the hole. For non-ferrous metal alloys, sheet steel, plastics. The HSS countersink with hexagonal shank is manufactured according to DIN 335. The best results are achieved when working at a low cutting speed. Hexagonal shank, for use with impact wrenches.
