CoroDrill® 860 is fast, economical, problem-free drilling. Low cutting forces give you fewer problems with weak fixturing, thin walled components, and loads on the cutting edge. With excellent chip evacuation at high cutting data in long and short chipping materials, CoroDrill 860 provides consistently problem-free drilling at high penetration rates.
The CoroDrill 860 product offer consists of two drill geometries, one optimized for steel and one optimized for aluminum. The drill comes in lengths 3-8×D as standard.
Benefits
- Higher achievable cutting data
