Features
Cobalt alloy construction delivers higher heat resistance and improved wear life when drilling hard metals such as stainless steel and alloy steels.
12″ extension length enables deep or recessed hole drilling without repositioning the workpiece, expanding accessible bore zones.
Rigid design minimizes deflection during heavy metal cutting tasks, helping maintain hole alignment under load.
Extended-reach geometry tailored for metalworking scenarios where long reach and durable cutting performance are required.
