Bosch Robust Line 13 Piece HSS-TiN Drill Bit Set

The Bosch Robust Line 13 Piece HSS-TiN Drill Bit Set is a titanium-nitride coated HSS drill bit set designed for drilling holes in metal. Each bit is ground from high-speed steel (HSS) to a high surface quality, which allows for extended usage. With the appropriate cooling agent, the TiN coating gives low friction and minimal wear.

This set suits alloyed and non-alloyed steel, malleable cast iron, sintered iron, new silver, copper and bronze. It also drills hard plastics such as perspex. The cylindrical shank (equal to the bit diameter) suits drill stands and drill drivers, and fits three-jaw drill chucks.

Each bit is manufactured to DIN 338 as a Type N (flute angle) with a 135-degree tip and a diameter tolerance of h8. The pointed split-point tip gives active cutting and accurate centring without wandering. Do not use these bits on aluminium, and only work with a cooling agent.
