Dewalt Accessories DD5109 Titanium Impact Drill Bit 9/64 in

Product Description

The DEWALT ACCESSORIES DD5109 is a 9/64-inch titanium-coated impact drill bit engineered for use in 1/4-inch hex shank impact drivers. The patented web taper increases bit rigidity, reducing the risk of breakage under the high-torque conditions common in impact driving applications. A split point tip eliminates bit walking at start and produces clean, burr-free holes without requiring a center punch. The titanium coating extends wear life compared to standard high-speed steel. This bit is suited for trade professionals and experienced DIYers who need consistent performance when drilling through metal, wood, or plastic.

The DD5109 is designed for use in 1/4-inch hex shank impact drivers, making it compatible with the cordless impact tools widely used by electricians, plumbers, HVAC technicians, and general contractors. Typical applications include drilling pilot holes and clearance holes in sheet metal, structural wood, and plastic enclosures. The package contains 5 bits, providing replacements for high-volume drilling tasks on the jobsite. The split point geometry is especially useful when starting holes on curved or slick metal surfaces where a standard drill point would skate.

Compatibility

Designed for use in 1/4-inch hex shank impact drivers. Suitable for drilling holes in metal, wood, and plastic across a wide range of cordless impact driver platforms.

Installation Notes

Insert the 1/4-inch hex shank fully into the impact driver chuck before operation. Ensure the workpiece is secured before drilling to prevent movement. When drilling metal, use an appropriate cutting fluid to reduce heat buildup and extend bit life. Inspect each bit for cracks or excessive wear before reuse, and replace any bit showing signs of damage.
