Tool maker Osborn has developed a technology which it claims can boost machine drilling times by up to 57% and prolong tool life.

Constant Rake Lip technology is said to prevent exposure of the drill’s outer corners to high thermal and abrasive stresses. The firm has launched the Cor-L drill based on the technology. It avoids the weaknesses in conventional drill geometry, the company says, as its outer corner geometry is not constrained by a straight-lip design.
