Handle Boring and Installation Jig — precise, durable tool for consistent handle and knob holes in doors, cabinets, and furniture Key benefits Accurate alignment: Builtin drill guide and boring hole locator ensure consistent hole placement for door knobs and pulls, reducing rework and misaligned hardware. Durable construction: Stainless steel components and an Lshaped aluminum alloy backer provide longlasting rigidity and reliable performance through repeated use. Fast, repeatable setup: Measurement scale and locator enable quick setup and repeatable hole positioning, speeding up installation across multiple doors or cabinet doors. Controlled positioning and depth: Hole positioning and depth control up to 205*100mm (with ruler) for precise placement without guesswork. Stable drilling: Stable structure minimizes movement and prevents misalignment on a variety of wood surfaces, improving finish quality. What's included and materials Locator with Lshaped aluminum alloy backer for stability and straight edge alignment Measurement scale (ruler) for accurate positioning and depth control up to 205*100mm Stainless steel construction on the main components for durability and corrosion resistance How it helps you Saves time by simplifying layout and drilling steps for repetitive installations Reduces mistakes when fitting knobs and pulls, so hardware installs squarely and consistently Works reliably on interior doors, cabinet doors, drawer fronts, and other woodworking surfaces Typical applications Installing or replacing door knobs and backsets on interior doors Fitting pulls and knobs on kitchen or bathroom cabinet doors and drawers Furniture restoration and woodworking projects where precise, repeatable hole placement is required Compatibility and performance Designed for use with common woodworking drills and standard door and cabinet hardware Effective across various wood types and panel materials due to rigid backer and guided drill path Measurement scale and stopper provide repeatable results for batch installations Simple to use, robust in the workshop: this handle boring and installation jig gives accurate alignment, strong material construction, and controlled hole positioning for professionallooking hardware installation.
