Dewalt DW1627 Black Oxide Drill Bit 7/8 in Reduced Shank

Product Description

The DEWALT DW1627 is a black oxide drill bit designed for metal drilling applications. It features a 7/8-inch diameter with a reduced shank profile that steps down to a 1/2-inch shank, allowing it to seat in standard 1/2-inch drill chucks without requiring a larger chuck capacity. Black oxide coating reduces friction and helps extend bit life during ferrous and non-ferrous metal drilling. This bit is sized for production and maintenance work where a large-diameter hole is needed in steel, iron, or similar materials, and is commonly used by electricians, plumbers, HVAC techs, and general tradespeople.

The DW1627 is suited for residential and light commercial applications where drilling large-diameter holes through metal framing, brackets, enclosures, or structural members is required. The reduced shank design makes it compatible with the most common 1/2-inch keyed and keyless drill chucks already in use on job sites, eliminating the need for specialty tooling or larger drill equipment.

Key Features

• 7/8-inch cutting diameter for large-hole metal drilling
• Reduced shank steps down to 1/2 inch for use in standard drill chucks
• Black oxide coating reduces friction and resists corrosion during use
• Designed for ferrous and non-ferrous metal drilling applications
• Sold individually (each)

Compatibility

Designed as an OEM-style replacement or direct-use bit compatible with standard 1/2-inch keyed and keyless drill chucks used in corded and cordless drill drivers.

Installation Notes

Install the reduced shank fully into the drill chuck and tighten securely before use. Use appropriate cutting fluid or lubricant when drilling through hardened or thick steel to reduce heat buildup and prolong bit life. Always wear eye protection and secure workpieces before drilling. Follow applicable workplace safety standards when operating rotary drilling equipment.
