The CoroDrill 860 for steel drilling is especially useful for conventional drilling, chamfered holes, inclined surfaces, cross holes, stack drilling and convex/concave surfaces. With excellent chip evacuation control, when using high cutting data in long and short chipping materials, the drill provides consistently problem-free drilling at high penetration rates, the company says.
 
The unique geometry combined with the new flute shape provides a cutting edge shape for effective clearance of the chip, even at increased penetration rates.
 
Low cutting forces provide fewer problems with weak fixturing, thin walled components and loads on the cutting edge.
 

The drill comes in lengths of 3 to 8 × D as standard.
