Drill Bit for Large-Hole Drilling
The Drill America 1-7/64in HSS Silver and Deming drill bit fits a standard 1/2in reduced shank so it can be used in larger drill presses and heavy-duty portable drills. Its surface-treated flutes are designed to clear chips efficiently when boring through steel and other tough materials. The overall length is 6in with a 3in flute length, giving adequate reach for through-hole work. This accessory targets maintenance shops and fabricators who need a single large-diameter bit for occasional production tasks.
Sustained-Cutting Behaviour
High-speed steel construction allows the cutting edges to resist softening during extended cuts, while the surface treatment reduces friction so heat builds more slowly than on untreated flutes. The reduced shank keeps the bit secure in a 1/2in chuck, limiting run-out that would otherwise worsen as the tool warms. In continuous drilling the flute geometry evacuates swarf steadily, preventing packing that can stall the cut. The bit is not suited for high-volume CNC cycles where carbide tooling and coolant systems are standard.
