Key benefits Prevents bit slip and keeps drilling accurate: the high‑hardness aluminium alloy clamping head holds bits firmly so drilling does not shift. Fits and adapts to most electric drills: if your drill chuck is smaller or loose, wrap winding tape around the drill head to increase diameter or secure the fit. Reduces hand fatigue and improves control: the ergonomic joystick‑style handle and internal mechanism make squeezing and operating the tool easier and more consistent. Durable, reliable performance for a wide range of materials and tasks. Features and specifications Clamping head material: high‑hardness aluminium alloy for stable, long‑lasting clamping. Handle design: ergonomic joystick-style mechanism to improve grip and squeezing ease. Compatibility: designed for use with electric drills. Adjust fit by adding winding tape when the drill chuck is too small or loose. Function: secure clamping for precise drilling operations. How it solves common problems Slipping or shifting bits: rigid aluminium clamp prevents movement during drilling, improving accuracy and reducing rework. Misfit with drill chucks: simple tape adjustment lets you adapt the accessory to different chuck diameters quickly, without tools. Hand strain during repetitive drilling: the joystick‑style handle design reduces effort required to squeeze and control the accessory. Practical use scenarios Furniture assembly and woodworking: accurately drill holes in wooden boards and panels for dowels, screws, and fittings. Metal and aluminium fabrication: stable clamping for drilling aluminium profiles, plates, and frames without bit wander. Home renovation and general DIY: reliable drilling through profiles, plates and other common materials during repairs and installations. Usage note If the drill chuck is too small, wrap winding tape around the drill head to increase diameter for a snug fit. If the drill is loose, add tape to secure the accessory and prevent movement. This product provides a simple, durable way to improve drilling stability and fit across a range of electric drills and materials.
