QC21PM jobber drills have a 135 degree split point which helps with self-centering and reduces the amount of force needed to drill into the workpiece. The premium High Speed steel used in manufacture means the tools are suitable for drilling a range of materials, including steels, stainless steel and aluminum, whilst the bright finish ensures clean and accurate holes by preventing workpiece material from sticking to the cutting edges of the tool. Available in an extensive range of metric sizes from 1.50 mm to 17.50 mm, QC21PM jobber drills have a specially designed parabolic flute, enabling drilling deeper holes in a single pass.
