Dewalt Accessories DD5128 Titanium Impact Drill Bit 7/16 in

Product Description

The DEWALT ACCESSORIES DD5128 is a 7/16-inch titanium nitride coated impact drill bit engineered for use in 1/4-inch hex shank impact drivers. The bit features a patented web taper design that increases rigidity and reduces the likelihood of breakage under high-torque conditions. A patented Pilot Point tip minimizes bit walking at the start of a hole and produces clean, burr-free results. Sold in a 3-pack, the DD5128 is built for professional tradespeople who need consistent, repeatable hole quality in demanding applications across metal, wood, and plastic substrates.

This bit is suited for residential and commercial jobsite work where an impact driver is the primary drilling tool. The 1/4-inch hex shank provides a secure, quick-change connection in standard impact drivers. The titanium nitride coating supports faster chip extraction and extends working life compared to uncoated high-speed steel bits. Electricians, plumbers, HVAC technicians, and general contractors will find this bit useful for anchor holes, conduit work, strap mounting, and general fastening tasks requiring clean through-holes in mixed materials.
