The DIABLO DMD3164JB is a 31/64-inch metal drill bit designed for drilling through ferrous and non-ferrous metals in professional trade applications. Built for durability under repeated use, this bit is sized for precision hole-making in steel, iron, aluminum, and similar materials. At approximately 3.94 inches in overall length and 0.98 inches in diameter, it fits standard drill chucks used by electricians, plumbers, HVAC technicians, and general contractors when routing conduit, pipe, or mechanical penetrations through metal framing and components.
This drill bit is suited for both residential and light commercial work where accurate metal drilling is required. Common applications include drilling through metal studs, electrical enclosures, HVAC ductwork flanges, plumbing brackets, and similar structural or mechanical metalwork. It is intended for use with standard corded or cordless drills and drill presses operating at appropriate speeds for the metal being drilled.
Designed as an OEM-style replacement or professional-grade drill bit for standard drill chucks accepting round or hex-shank bits in 31/64-inch diameter configurations.
Metal drilling should be performed by qualified trade professionals using appropriate speed settings for the material being drilled - higher speeds for softer metals, lower speeds for hardened steel. Use cutting fluid or a cooling lubricant when drilling thicker or harder metals to extend bit life and prevent overheating. Secure the workpiece before drilling to prevent movement. Always wear eye protection when drilling metal.
