Key benefits Ultraprecise measurements for wood and metal projects, enabling accurate planning and finishing. Capable of capturing small measurements down to 0.1 mm for tight tolerances. Four measurement modes provide versatile options for common tasks without swapping tools. The 0 button allows easy recalibration to zero and quick comparison with previous readings. Simple, straightforward operation designed for reliable, repeatable results. What to expect Four measurement modes for flexible use across external, internal, depth, and other common tasks. Immediate rezeroing with the 0 button to streamline successive measurements and comparisons. Built to support both woodwork and metalworking projects with consistent performance. Usage scenarios Woodworking alignment and fitting: verify board thickness, groove widths, and dowel or tenon sizing to ensure joints fit tightly and squarely. Metal fabrication checks: confirm stock thickness, slot widths, and pocket sizes before machining to reduce rework. Jig and fixture setup: quickly measure workpiece dimensions to set up jigs, clamps, and fixtures with repeatable accuracy. Compatibility and practicality Suitable for projects involving wood and metal where precise measurements are essential. Provides reliable, repeatable readings across multiple measurement modes for common workshop tasks. Clear zeroing capability to compare current measurements against reference values or previous setups. Note The caliper does not include a 100 mm depth gauge.
