Bosch 19 Piece HSS Titanium Drill Bit Set

The Bosch 19 Piece HSS Titanium Drill Bit Set is a metal drill bit set designed for fast, durable drilling in 0.5 mm steps from 1 mm to 10 mm. Each HSS bit has a high-grade titanium nitride (TiN) coating for a long service life and quick drilling progress. The set covers every size from 1 mm to 10 mm in 0.5 mm increments, so it suits tradespeople and competent DIYers who need a full range of metal drill bit sizes to hand. According to Bosch, the TiN coating gives up to 40% faster drilling progress than comparable bits without it, and up to 6 times longer service life when used with proper cooling. The bits are suitable for all power tool brands. Bosch recommends always using coolant, such as Bosch universal cutting oil 2 607 001 409. Do not use these bits in aluminium, and wear protective glasses during use.
