697604402530 BROWNELLS CARBIDE CENTER DRILL The Brownells Carbide Center Drill is an essential tool for gunsmiths, machinists, and firearm restorers faced with removing frozen screws, drilling out damaged fasteners, or starting holes in extremely hard materials. When conventional screw-removal methods fail, these solid carbide center drills create a precise starting point that allows an undersized drill bit to begin cutting without wandering into the screw slot or surrounding material. Their rigidity and cutting performance make them particularly effective when working with stubborn firearm screws and hardened components. Unlike standard drill bits that can flex or walk during startup, the Carbide Center Drill features a large body relative to its cutting diameter, providing exceptional stability and control. These tools are also highly effective for drilling broken taps, including hardened taps that are difficult to machine with conventional tooling. Available in four sizes, each drill is manufactured from durable carbide for long life and reliable performance in demanding gunsmithing and machine shop applications. FEATURES Designed to create precise starter holes in frozen or damaged screws. Helps prevent drill bits from wandering or catching in screw slots. Excellent for removing stubborn firearm screws and fasteners. Capable of cutting center holes in broken taps, including hardened taps. Solid carbide construction provides exceptional hardness and durability. Rigid design resists flexing and walking during drilling operations. Ideal for gunsmithing, machining, repair, and restoration work. Available in four sizes to accommodate various applications.
