Product Details
Cobalt drills are specifically engineered to cut through very hard metals, including stainless steel, and do not require a center punch due to their Century 135-degree quick cut points, which are self-centering for faster penetration and reduced pressure, preventing the drill from walking or wandering at the starting surface. These drills are highly heat resistant and must be used in power units that operate at a minimum RPM speed of 1,500 for maximum efficiency. They comply with Aerospace NAS 907-J specifications, ensuring they meet industry standards for performance and durability.
