Bosch Professional HSS Twist PointTeQ Drill Bit - 10pc, 3.9mm

The HSS Twist Drill Bit PointTeQ enables fast drilling in metal due to its PointTeQ tip design. Quick and easy drilling starts are possible as the self-centering tip prevents wandering. Because of its increased drilling rate, less heat and wear are generated. The PointTeQ tip design remains sharp and ensures continuous durability. This bit is suitable for drilling clearance and pilot holes in alloyed and non-alloyed steel, non-ferrous metals, cast steel, cast iron and plastics. There is a low risk of breakage, especially for drill bits below 6 mm in diameter as the bit is manufactured to have a highly elastic body. Its black-oxide coated flute provides fast chip removal. The HSS Twist Drill Bit PointTeQ is manufactured to DIN 338. The drill bit is Type N (flute angle) with a tip of 135 degrees. It has a cylindrical shank system (shank equal to drill bit diameter) and is intended for use in drill stands and drill drivers.
