Cobalt Drill Bits

Our premium cobalt drill bits can cut through various work-hardened and abrasive materials, including stainless steel, and metals such as cast iron, bronze, and titanium have no chance against our premium-quality cobalt drill bits for sale. Our cobalt drill bits meet ANSI standards, are available in sizes up to 1/2″, and feature a heavy-duty 135-degree split point design for quick drilling. All cobalt drill bits 3/16″ and up have ground 3-flat shanks to prevent slippage. DBW cobalt drill bits for hardened steel are a great choice for cutting through weld seams. We carry a wide variety of lengths, consisting of a jobber, stub-screw machine, and aircraft extension for hard-to-reach places.

For tougher metalwork, cobalt drill bits help maintain cutting strength when heat builds at the point of contact. Shops often choose cobalt drill bits for metal when drilling stainless steel, cast iron, or hardened materials that can wear out standard bits too quickly. A sharp cobalt drill bit also supports cleaner starts and better control when drilling through weld seams or thicker stock. For repeated metal drilling, cobalt drill bits offer strong value.
