Dewalt DW1629 Black Oxide Drill Bit 1 in Reduced Shank

Product Description

The DEWALT DW1629 is a black oxide reduced shank drill bit designed for drilling into metal. It features a 1 inch cutting diameter with a 1/2 inch reduced shank, allowing it to fit standard 1/2 inch drill chucks without requiring a full-diameter shank. The black oxide finish reduces friction and helps extend bit life during metal drilling applications. This bit is sized for tasks that demand a large-diameter hole in ferrous and non-ferrous metal, and it is typically installed by electricians, pipefitters, HVAC technicians, and general contractors who need to bore large holes through metal framing, enclosures, or structural members.

The DW1629 is suited for use with corded or cordless drills equipped with a 1/2 inch chuck. The reduced shank design makes a 1 inch diameter bit accessible on standard drill drivers without the need for a larger chuck size. Common applications include boring holes in sheet metal, steel plates, metal studs, and electrical enclosures in both residential and commercial construction settings. It is sold individually and is appropriate for job site use where a large-diameter metal hole is required on standard equipment.

Key Features

• 1 inch cutting diameter for large-bore metal drilling applications
• 1/2 inch reduced shank fits standard 1/2 inch drill chucks
• Black oxide finish reduces friction and heat buildup during drilling
• Designed specifically for metal drilling including ferrous and non-ferrous materials
• Sold individually, compatible with common job site drill equipment

Compatibility

Designed as an OEM-style replacement and standard-fit drill bit for use with 1/2 inch chuck corded or cordless drills rated for large-diameter metal drilling.

Installation Notes

Insert the 1/2 inch reduced shank fully into the drill chuck and tighten securely before use. Always wear appropriate eye protection and secure the workpiece before drilling. Use a center punch to mark the drill point on metal surfaces to prevent bit walking. Reduce feed pressure as the bit breaks through the material to maintain control and protect the cutting edge.
