Efficiencyboosting spiral design The spiral geometry is engineered to maximize material removal and drilling speed across wood, metal, and plastic. This results in cleaner holes and faster progress, making it a practical addition to your toolkit. Stable hex shank connection 1/4 inch hex shank provides a secure, stable fit with most power tools. This design minimizes slippage during operation and enhances control and precision. Robust speed steel construction Made from speed steel for durability and wear resistance. Built to withstand speed drilling applications without sacrificing strength or integrity. Integrated center punch for accuracy The builtin center punch aids in precise positioning, helping prevent wandering and delivering consistently centered holes. 23 practical use scenarios Furniture assembly and cabinetry: drill clean pilot holes in hardwoods and plywood for screws and dowels with minimal wandering. Metalworking: start and drill through aluminum or light steel profiles with reliable accuracy and control. Home improvement and general use: drill through plastics, PVC, or composite materials for wiring, hinges, or hardware installations.
