Frequently Bought Together
A selection of 19 good quality metric, high speed steel drill bits for drilling most metals, wood and plastics. When drilling, increased friction and heat can cause bits to lose their hardness but the high speed steel makes these bits more resistant to wear. The grinding process adds to the rigidity, makes for a clean cut and they'll hold their edge for longer.
Sizes range from 1-10mm in 0.5mm increments, housed in an indexed drill holder for easy selection. Precision ground for a fast clean cut.
