Product Details
Cobalt drills are engineered for cutting through exceptionally hard metals, including stainless steel, and eliminate the need for a center punch thanks to their Century 135-degree quick cut points, which are self-centering and facilitate faster penetration with reduced pressure, preventing walking or wandering at the starting surface. Designed for extreme heat resistance, these drills must be operated in power units with a minimum RPM speed of 1,500 for maximum efficiency. They adhere to Aerospace NAS 907-J specifications, ensuring high quality and reliability.
