DeWalt Brad Point Wood Drill Bit – DT4520QZ

The DeWalt Brad Point Wood Drill Bit in 20mm is the largest in this range, providing a substantial bore for heavy-duty structural applications including large pipe and conduit passages, significant bolt clearance holes, and specialist large-format joinery in thick hardwood and softwood timbers. Precise cutting edges prevent splintering around the full 20mm diameter, ensuring a clean, professional result even in demanding or knotty timbers. The brad point tip anchors the bit firmly on the workpiece, eliminating any tendency to wander and maintaining hole accuracy on large, complex structures. Engineered flutes are built to handle the high chip volume produced at this cutting diameter, sustaining efficient, clog-free performance throughout the bore. Constructed from chrome-vanadium alloy steel and hardened and ground centric, this 20mm bit delivers the robustness and precision that professional contractors depend upon. Features and Benefits: • Precise cutting edges minimise splintering for clean results • Brad point tip prevents walking on entry • Engineered flutes for effective chip removal • Chrome-vanadium alloy steel for professional-grade durability • Hardened and ground centric for accuracy • Suitable for plywood, hardwood, and softwood
