Product Details
Cobalt drills are designed for cutting through extremely hard metals such as stainless steel. They feature Century 135 degree quick cut points that are self-centering, allowing for faster penetration with less pressure, effectively preventing walking or wandering at the starting surface. These drills exhibit exceptional heat resistance and must be operated in power units with a minimum RPM speed of 1,500 for maximum efficiency. The drills comply with Aerospace NAS 907-J specifications, ensuring high performance and quality standards.
