Beskrivelse
Bosch 1 metal drill HSS-G 7x69x109 mm
- self-centering drill tip, cross-grinding, tip angle 135°, active drill bit for perfect centering
- precision-ground drill made of HSS steel for fast working
- up to 10 mm diameter, no punching or pre-drilling required
The ground HSS twist drill drills in metal with highest precision. The self-centering drill tip with cross-grinding and a point angle of 135 degrees allows perfect centering without wandering. The cross-ground drill tip eliminates the need for center punching or pre-drilling up to 10 mm diameter. This precision-ground HSS steel drill drills 40% faster and requires 50% less contact pressure than conventionally ground HSS drills. It is suitable for drilling holes in alloy and non-alloy steel, cast steel, cast iron, sintered iron, malleable iron, non-ferrous metals and hard plastics. The shank is cylindrical (the shank diameter corresponds to the drill bit diameter). It is used with drill stands and drill screwdrivers.
