Dewalt DW1608 Black Oxide Drill Bit 5/16 X 12 Inches

Product Description

The DEWALT DW1608 is a black oxide-coated twist drill bit engineered for metal drilling applications. Measuring 5/16 inches in diameter and 12 inches in length, this extended-length bit is built for reaching deep into workpieces where standard-length bits cannot. The black oxide finish reduces friction during drilling and provides a moderate level of corrosion resistance. This bit is suited for use by electricians, plumbers, HVAC technicians, and general contractors who need to bore through metal framing, conduit hangers, brackets, and similar ferrous and non-ferrous materials on the job site.

The DW1608 is sized for applications that demand extra reach, making it a practical choice for boring through thick assemblies, deep channel stock, or stacked materials in tight spaces. Its 5/16-inch diameter is a common size for conduit knockout work, anchor bolt clearance, and structural fastener holes. It is sold individually, allowing technicians to replace single bits without purchasing a full set.

Key Features

• Black oxide coating reduces friction and extends bit life in metal drilling applications
• Extended 12-inch length provides reach for deep-hole applications
• 5/16-inch diameter suits conduit, fastener, and anchor bolt work
• Designed for use in standard keyed and keyless drill chucks
• Sold individually — unit of measure is each

Compatibility

Designed as an OEM-style replacement or service bit compatible with standard 3/8-inch and 1/2-inch drill chucks used in corded and cordless drills common to HVAC, electrical, and plumbing trades.

Installation Notes

This bit is installed and used by licensed electricians, plumbers, HVAC technicians, and general tradespeople. Secure the bit firmly in the drill chuck before use and verify chuck tightness to prevent slippage. When drilling through metal, use appropriate cutting fluid or lubricant to reduce heat buildup and extend bit life. Always wear eye protection and follow applicable OSHA safety standards when drilling into structural or mechanical components.
