Dewalt Accessories DWA1181 21-piece Drill Bit Set

Product Description

The DEWALT ACCESSORIES DWA1181 is a 21-piece black and gold drill bit set built for heavy-duty drilling in plastic, wood, and metal. Each bit is made from high-speed steel with a black and gold coating that resists rust and extends service life. The 135-degree split point tip starts on contact and prevents the bit from walking on smooth surfaces. A tapered web design runs the length of the flutes to reduce breakage under load. The 3-flats shank reduces spin-out in the chuck for consistent torque transfer, and size markings on the shank allow for fast identification without guesswork.

This set is suited for general trade and maintenance work across residential and light commercial applications. Electricians, plumbers, HVAC technicians, and carpenters reach for a set like this when drilling pilot holes, mounting hardware, and running fasteners through a range of substrate materials. The 21-piece range covers the common drill sizes needed on a typical service call or installation job.

Installation Notes

Drill bits of this type are installed and used by any trade requiring field drilling. Secure the bit fully into the chuck before operation and confirm the shank is seated against all three flats to prevent slipping. Match bit size to fastener or hole specification before drilling. When drilling metal, use appropriate cutting speed and avoid forcing the bit, which can cause overheating and premature wear.
