Chip evacuation hole design ensures smooth removal of wood chips and makes drilling faster and easier. The seamless fit between the drill and the metal guide hole provides smooth drilling. Its 15-degree angle easily engages wood and forms strong, visually appealing joints between furniture pieces. Equipped with clear, precise metric scales, you can set the drilling position based on the wood thickness for accurate results. This tool features integrated magnets and a multi-gear slot design and can be adjusted within a range suitable for different board thicknesses (0.5 to 1.5 inches). Use scenarios - Furniture assembly: achieve consistent, strong joints with accurate hole placement. - Shelving and cabinetry: adapt to varying board thicknesses using the adjustable scale for precise drilling positions. - Repairs and reinforcements: drill with a controlled angle and depth to strengthen existing frames.
