Dewalt Accessories DW1110 Black Oxide Drill Bit 5/32 in 2pk

Product Description

The DEWALT ACCESSORIES DW1110 is a 5/32-inch black oxide twist drill bit sold in a pack of two. It features a 135-degree split point that drills on contact and prevents walking, reducing the need for a center punch on most work surfaces. A patented core diameter design lowers the risk of bit breakage under load. The black oxide finish increases surface hardness and wear resistance compared to bare high-speed steel, extending service life across repeated use in metal, plastic, and wood. A 3-flats shank design prevents spin-out in standard keyed and keyless chucks, maintaining consistent grip during high-torque drilling.

The DW1110 suits general-purpose drilling tasks encountered by electricians, plumbers, HVAC technicians, and carpenters working in light fabrication, rough-in, and fixture installation. The 5/32-inch diameter is a common size for pilot holes, sheet metal work, and conduit and bracket mounting applications. The two-piece pack provides a backup bit on the job site without requiring a full set purchase.

Installation Notes

Installation is performed by any trade professional using a corded or cordless drill with a compatible chuck size. Secure the 3-flats shank fully in the chuck before drilling to ensure proper grip and reduce wobble. When drilling metal, use appropriate cutting fluid or lubrication to extend bit life and reduce heat buildup. Inspect the bit for wear or tip damage before each use and replace if the split point shows visible rounding.
