Features
Cobalt alloy construction provides enhanced heat resistance and wear life when drilling through hard metals compared with standard HSS.
11/16″ cutting diameter enables larger holes with a single bit, reducing tool changes in metalworking projects.
1/2″ reduced shank design maintains cutting diameter while a smaller shank profile supports tighter work envelopes.
Single-piece design enhances cutting edge integrity and stability under higher temperature drilling conditions.
Metalworking focus suited for harder materials; use with proper feed rate and lubrication to optimize performance and tool life.
