Dewalt DW1612 Black Oxide Drill Bit 7/16x12 in Metal

Product Description

The DEWALT DW1612 is a black oxide-coated twist drill bit engineered for metal drilling applications. At 7/16 inches in diameter and 12 inches in length, this bit is suited for deep-hole drilling in ferrous and non-ferrous metals. The black oxide finish reduces friction and helps extend bit life under repeated use. Licensed electricians, HVAC technicians, plumbers, and general contractors rely on long-series bits like this when standard-length bits cannot reach fastener locations or penetrations through structural members.

This bit is designed for use with corded or cordless drills and drill presses capable of accepting a 7/16-inch shank. The 12-inch length makes it well-suited for drilling through wall plates, floor joists, and metal framing during rough-in work. It is a common tool in electrical and mechanical trades where deep clearance holes are required for conduit, pipe, or cable routing through metal substrates.

Key Features

• 7/16-inch diameter for standard conduit and pipe clearance applications
• 12-inch overall length provides reach for deep drilling through structural members
• Black oxide coating reduces surface friction and resists corrosion during storage
• Long-series design suited for through-wall and through-joist penetrations
• Sold individually, one bit per unit

Compatibility

Designed as an OEM-style replacement or direct-use drill bit compatible with standard corded and cordless drills and drill presses that accept a 7/16-inch round shank.

Installation Notes

This bit is installed and used by electricians, plumbers, and HVAC technicians during rough-in phases. Secure the workpiece before drilling and use appropriate cutting fluid when drilling through hardened or thick metal stock to reduce heat buildup. Wear appropriate eye protection per OSHA and job-site safety requirements. Inspect the bit for wear or damage before each use and replace if the cutting edges are chipped or the shank is deformed.
