Dewalt Accessories DW1120 Black Oxide Drill Bit 5/16 in 2 Pack

Product Description

The DEWALT ACCESSORIES DW1120 is a 5/16-inch black oxide drill bit sold in a pack of two. It features a 135-degree split point that drills on contact and eliminates walking, reducing the need for a center punch. A patented core diameter and tapered web design reduce bit breakage under load. The black oxide finish increases wear resistance and provides corrosion protection, extending service life when drilling through metal, plastic, and wood. A 3-flats shank prevents spin-out in the chuck, and size markings on the bit allow for quick identification during use.

These bits are suited for general drilling tasks in metal fabrication, woodworking, and plastics. The 135-degree split point geometry makes them well-suited for harder materials where a standard 118-degree point would walk or require additional layout steps. Tradespeople and experienced DIYers will find the two-pack format practical for keeping a spare on hand when one bit is worn or dedicated to a specific task on the job site.

Installation Notes

Installation is performed by tradespeople and experienced users using standard corded or cordless drills with a 3-jaw chuck. Secure the 3-flats shank firmly in the chuck before operation to prevent slippage. When drilling metal, use appropriate cutting fluid to extend bit life and reduce heat buildup. Inspect the bit for wear or damage before each use and replace if the cutting edges are dull or chipped.
