Product Details
Black oxide drill bits are manufactured from industrial high-speed steel, surface treated for high performance and long life. The kit is designed to drill common steel (flat bar, angle iron, tubing), wood, and plastic. No center punch is needed as Century quick cut points are self-centering and penetrate faster with less pressure, ensuring they will not walk or wander at the starting surface. These drill bits are manufactured to aerospace NAS 907-B specifications, providing high durability and compliance with industry standards.
