Brownells #28 Drill Bit

The Brownells #28 Solid Carbide Drill Bit is built for the demanding task of drilling into hardened firearm components, delivering the precision and control professional gunsmiths rely on. Its singleflute geometry cuts clean, consistent chips even in extremely hard steels, producing true, chatterfree holes without crumbling the material or workhardening the surface. At 2 inches long, it offers the quill clearance needed when working with scope and sightmounting jigs, making it easy to use in tight or specialized setups. When properly handled, this carbide bit resists binding and breakage, and its cutting action helps prevent the hardened hole surfaces that often lead to tap failure during threading.
