About this product
This DEWALT Extreme Flatwood drill bit is designed for fast, accurate drilling in hardwood, softwood, chipboard and other man-made materials, including timber that may contain buried nails. It suits tasks such as door lock fitting, mortising, and electrical or plumbing work. The bit has an extra-thick, robust steel shank with a full-length heat treatment for durability against bending and breaking. Chamfered outer cutting spurs give clean, fast drilling and extended life, while the precision-ground central point aids faster penetration. A 1/4" hex fitting prevents slipping in the chuck, and a hang hole allows for storage or wire pulling. Diameter: 40mm. Length: 152mm.
