Solid-aluminum 45° center marker and centering tool that finds the exact center of round and square bearings while providing strong, accurate 45-degree measurements. Key benefits Durable construction: made from solid aluminum for long-lasting strength and reliable repeat use. Accurate marking: designed to deliver precise 45° measurements and clear center points, reducing layout errors. Versatile centering: locates the center of both round and square bearings quickly and consistently. Time and effort savings: simple, repeatable operation speeds marking and measuring on each workpiece. Suitable for all skill levels: built for professional tradesmen and accessible to DIY woodworking enthusiasts and hobbyists. Main features Material: solid aluminum for durability and stable measurements. Function: 45° marker combined with a center-finding tool for round and square bearings. Performance: consistent, accurate center marks and angle measurements to improve fit and alignment. How it solves common problems Eliminates guesswork when finding bearing centers, preventing misaligned assemblies and rework. Replaces slower or less accurate methods (visual centering, improvised jigs) with a repeatable tool. Reduces layout time on cabinets, furniture parts and other projects that require precise center and angle marking. Practical use scenarios Furniture assembly: quickly mark the center of dowel holes and bearing positions to ensure parts align during glue-up and fastening. Cabinet installation and repair: find exact centers for hinges, hardware, and bearing locations to avoid shifting and uneven gaps. General woodworking projects: fast center-finding and 45° layout for turned parts, trim work, and bearing-mounted components. What to expect in use Place the tool against the workpiece, align to the bearing or edge, and mark the center or 45° reference. Durable aluminum construction maintains shape and measurement accuracy over repeated use. Works equally well for trade professionals and home workshop users who need reliable center and angle layout. No unnecessary features — just a sturdy 45° marker and centering tool that simplifies accurate marking of round and square bearings for furniture, cabinets, and other woodworking projects.
