High-strength fully ground annular cutters that are machined under the effect of plasma with a hard coating in the range of 2.5 µ . As a result, these tools have considerably longer life and more uniform removal of chips, particularly with long drills. An important aspect for occupational
Fully ground annular cutters made of high-speed steel with carbide coating. Highly economic due to increased service life, more work safety due to good chip flow, especially in the case of long annular cutters. BDS recommends the high performance cutting oil BDS 5000.
