Dewalt Accessories DW1130 Black Oxide Drill Bit 15/32 in 2pk

Product Description

The DEWALT ACCESSORIES DW1130 is a 15/32-inch black oxide drill bit sold as a 2-pack, designed for trade and professional use across metal, plastic, and wood applications. The 135-degree split point tip engages on contact, eliminating bit walking and producing clean, accurate holes without a center punch. A patented tapered web core reduces breakage under heavy drilling loads. The black oxide finish increases surface hardness and slows wear, extending bit life compared to uncoated alternatives. A 3-flats shank prevents spin-out in standard drill chucks, keeping the bit seated under torque.

These bits are suited for residential and light commercial work where a reliable general-purpose drill bit handles varied material types. Electricians, plumbers, HVAC techs, and general contractors reach for this size when drilling through sheet metal, conduit knockout areas, plastic enclosures, and dimensional lumber. The 2-pack format is practical for job-site use where a backup bit is standard practice. The 15/32-inch diameter is a common size for clearance holes, pilot holes for larger fasteners, and knockout applications.

Installation Notes

Installation is performed by electricians, plumbers, HVAC technicians, and general tradespeople using a standard corded or cordless drill or drill press. Secure the 3-flats shank firmly in the chuck before drilling to prevent slippage. When drilling metal, use cutting fluid or oil to reduce heat buildup and extend bit life. Always wear appropriate eye protection and secure the workpiece before drilling.
