DART 10mm Flat Bit

The DART Flat Wood Bit is engineered for high-speed performance in the most demanding wood-drilling applications. Unlike standard twist drills, the flat bit design uses a sharp central “brad” point to ensure 100% accuracy when starting a hole, followed by optimised side spurs that slice through wood fibers to leave a cleaner exit hole with minimal splintering. Each bit is manufactured from high-quality carbon steel, which has been fully heat-treated for maximum durability and resistance to bending. The 1/4″ hexagonal shank is a key feature, providing a universal fit for both standard drill chucks and quick-change impact drivers. This hex design is crucial for high-torque tasks, as it prevents the bit from spinning or slipping under heavy load. These bits are an essential tool for fencers and landscapers when drilling through fence posts, sleepers, or joists for bolts and fixings. They are equally effective for electricians and plumbers needing to run cables or pipework through timber frames. Available Sizes & Specific Uses: 10mm Flat Bit: The ideal size for drilling pilot holes for heavy-duty bolts and creating clearance holes for small pipework or cables in timber. 12mm Flat Bit: A versatile trade size, perfect for installing M10 bolts or larger threaded rods through fence posts and sleepers. 13mm Flat Bit: Commonly used for slightly larger fixings and providing extra clearance for 12mm rods or specialised electrical conduits.
