Product Details
Cobalt drills are engineered to effectively cut through very hard metals, including stainless steel, without the need for a center punch, thanks to their Century 135-degree quick cut points that offer self-centering capabilities for faster penetration with reduced pressure, preventing any walking or wandering at the starting surface. These drills are highly heat resistant and are designed to be used with power units that operate at a minimum RPM speed of 1,500 for maximum efficiency. They conform to Aerospace NAS 907-J specifications, ensuring their reliability and performance in demanding applications.
