Extremely robust: the production of solid metal leads to an extremely robust body of the Impact Control HSS twist drill. High Durability: Precision ground spiral groove for reduced wear when drilling. The use of e.g. oil as a coolant, also extends the life of the spiral drill. Precise work: active cutting with low contact force and perfect centring thanks to split point drill tip. Areas of application: suitable for use in alloyed and unalloyed steel, cast iron, sintered iron, non-ferrous metals, sheet metal and plastic. Compatibility: suitable for all impact drills, drills and drill stands with hexagonal shank mount.
