Diablo DMD12JB Metal Drill Bit 1/2 Inch

Product Description

The DIABLO DMD12JB is a 1/2-inch metal drill bit designed for drilling through steel, iron, and other ferrous and non-ferrous metals. It is built for professional tradespeople including electricians, plumbers, HVAC technicians, and general contractors who need consistent, clean holes in metal substrates. The 1/2-inch diameter makes it a standard-size choice for conduit knockouts, pipe clearance holes, and structural metal work. It is sized for use in standard 1/2-inch or larger keyed and keyless chucks found on corded and cordless drills commonly used in the trade.

The DMD12JB is suited for both residential and light commercial applications where metal drilling is required. Typical use cases include drilling through sheet metal, metal studs, electrical enclosures, and mechanical equipment panels. It is appropriate for bench-top drill presses as well as handheld drill-driver applications where controlled feed rate is maintained to preserve bit life and hole quality.

Installation Notes

Metal drill bits should be installed by a qualified tradesperson familiar with proper drilling technique for metal substrates. Always secure the workpiece before drilling and use appropriate cutting fluid or lubricant to extend bit life and reduce heat buildup. Wear appropriate personal protective equipment including eye protection when drilling metal. Power down and disconnect the drill before changing bits.
