RUKO Step drill HSSE-Co 5

More information: bit.ly/Stepdrill-HSSE-Co5
Step drill HSSE-Co 5, spiral fluted with split point.
It has a deep-ground and spiral flute with absolutely smooth running and high cutting performance. This means that, in particular, non-breaking chips are cleanly removed as with a twist drill. This prevents built-up edges and cold welding from forming on the cutting edges.

I've been using these for 4 years now, I'll NEVER go back to any other product. Honest. I even managed to cut through inox 254SMO with one of these bits.
