Woodworking Compass / Circle Ruler — Precision tool for marking, measuring and drawing accurate arcs and circles Key benefits Accurate measurements: Precisely engraved metric and imperial markings make it easy to read dimensions and transfer measurements without guesswork. Stable, repeatable arcs: The rigid design ensures smooth, consistent curves and circles with minimal deviation, reducing rework and improving fit. Built to last: Made from aluminum alloy for corrosion resistance and strength — resists rust and won’t crack or deform under normal use. Versatile: Combines measuring and scribing functions in one tool, reducing the number of instruments needed on the job. What it does for you Eliminates measurement errors with clearly etched dual-unit scales for both metric and imperial workflows. Produces reliable, steady arcs so cuts, router paths and scribed lines match your layout every time. Withstands workshop conditions for long-term use — ideal for professionals and hobbyists who need a durable marking tool. Key attributes Scale: Precise metric and imperial engraving for quick, unambiguous readings. Construction: Robust aluminum alloy — corrosion-resistant and durable. Function: Designed for marking, measuring, and drawing stable arcs and circles with consistent accuracy. Applications: Suitable for woodworking, metalworking, decorative design, industrial drawing and other precision layout tasks. Use scenarios Woodworking: Mark accurate circle centers and scribe arcs for table tops, jig layout, inlay work, and curved furniture components. Metalworking: Transfer precise radii and circle scribe lines on sheet metal or parts prior to cutting or machining. Design and drafting: Lay out decorative patterns, industrial templates or repeatable geometric shapes for production and prototyping. Why choose this tool Combines clear dual-unit measurement and a stable drawing platform in a single, durable aluminum tool, helping you work faster with fewer mistakes while lasting through repeated shop use.
