Dewalt DW1620 Black Oxide Drill Bit 9/16 in Reduced Shank

Product Description

The DEWALT DW1620 is a black oxide reduced shank drill bit designed for metal drilling applications. The 9/16-inch cutting diameter pairs with a 3/8-inch reduced shank, allowing it to fit standard 3/8-inch chuck drills without requiring a larger chuck size. Black oxide coating reduces friction during drilling and extends bit life compared to bare high-speed steel. This bit is suited for use by electricians, plumbers, HVAC technicians, and general contractors who need reliable metal penetration in the field or shop.

The DW1620 is intended for drilling through ferrous and non-ferrous metals commonly encountered in trade work, including mild steel, sheet metal, and similar materials. The reduced shank design makes it a practical choice when a 9/16-inch hole is required but only a 3/8-inch chuck is available on the drill. Minimum order quantity is 5 units per order, making it suitable for stocking by contractors and supply houses.

Key Features

• 9/16-inch cutting diameter for standard trade hole sizes in metal
• 3/8-inch reduced shank fits 3/8-inch chuck drills without an adapter
• Black oxide coating reduces friction and heat buildup during drilling
• Designed for metal drilling including mild steel and sheet metal
• Sold in minimum quantities of 5 per order

Compatibility

Designed for use with 3/8-inch chuck corded and cordless drills. Compatible with standard drill drivers used in HVAC, plumbing, and electrical trade applications requiring a 9/16-inch hole in metal substrates.

Installation Notes

Insert the 3/8-inch reduced shank fully into the drill chuck and tighten securely before use. Use appropriate cutting fluid or lubricant when drilling through thick steel to reduce heat and extend bit life. Wear eye protection and secure the workpiece before drilling. Inspect the cutting tip for wear or damage before each use and replace if the tip is chipped or dull.
