135 ° segmentation point is an automatic centering point for hardened steel..

The cobalt JBR length bit

Cobalt drill has a 135 ° split point (to be automatic centering), heaver construction, and greater thermal resistance. These tools are designed to drill hard, tough, high-strength materials such as stainless steel.

The service life of cobalt drilling rig in high speed steel, such as stainless steel, titanium and chromium alloy, has increased significantly.
