QC21GM HSS TiN QC 135D JL Drill Jobber DIN 338 2.50 mm

QC21GM drill bits are manufactured from High Speed Steel and can be used for drilling many materials including steel, aluminum and stainless steel, with a titanium nitride coating which increases the service life of the drill and improves performance when drilling harder materials. The special parabolic flute design means you can drill deeper holes in a single pass, whilst the 135 degree split point helps with self-centering and reduces the force needed to drill the hole. QC21GM jobber drills come in a range of different metric diameters from 1.50 mm to 13.00 mm.
