Product Details
Cobalt drills are engineered for precision cutting through extremely hard metals, including stainless steel. The kit includes drills featuring Century 135-degree quick cut points that are self-centering, allowing for faster penetration with minimal pressure, preventing the drill from walking or wandering at the starting surface. These drills are extremely heat resistant and must be operated in power units with a maximum RPM speed of 1,500 or more for optimal efficiency. They comply with Aerospace NAS 907-J specifications.
