Dewalt Accessories DD5155 Titanium Impact Drill Bit Set

Product Description

The DEWALT ACCESSORIES DD5155 is a 5-piece titanium impact drill bit set built for professionals who need fast, clean drilling in metal and other materials. The set features a patented web taper that increases bit rigidity and reduces the risk of breakage under impact loads. Each bit also incorporates a patented Pilot Point tip, which starts on contact for cleaner, burr-free holes and less bit walking compared to conventional split-point designs. This set is suited for electricians, plumbers, HVAC technicians, and general contractors working with hand or impact drivers on the job site.

This bit set is designed for trade professionals drilling holes in sheet metal, light steel, wood, and similar materials during installation work. The 5-piece assortment covers a practical range of sizes for rough-in and finish drilling tasks. The titanium construction extends bit life compared to standard high-speed steel, making it a reliable choice for repetitive drilling applications in the field or shop.

Installation Notes

Drill bits of this type are installed and removed by trade professionals using standard chuck or hex-shank impact driver connections — confirm the driver chuck is fully seated and locked before use. Always wear appropriate eye protection when drilling, as metal chips and debris are produced. Power down or unplug the tool before changing bits. Do not exceed the rated capacity of the drill or impact driver for the material being drilled.
