"Step drill HSS spiral grooved.
The deep-ground and spiral-shaped flute offers absolute smooth running and high cutting performance.
In particular, non-breaking chips are removed cleanly as with a twist drill.
This reduces the formation of built-up cutting edges and cold welding on the cutting edges.
The cone facilitates the retraction of bored plates.
