Precision measurement you can rely on: engineered aluminum height gauge provides accurate readings across the 3–26 mm range with ±0.01 mm tolerance, making fine height and depth adjustments consistent and repeatable. Durable, stable construction: lightweight anodized aluminum resists deformation while remaining rigid enough for workshop use. The clear royal/metric scale lets you read measurements quickly without secondguessing. Designed for workshop calibration: built for professional woodworkers and DIY enthusiasts who need a dependable tool to set and check heights on routers, router tables, and milling machines. Key benefits — why you need this gauge Eliminates guesswork: ultrafine tolerance and a precise scale reduce trialanderror adjustments, saving time and material. Longterm accuracy: anodized aluminum construction holds its shape under typical use, keeping settings reliable over repeated measurements. Fast setup: easytoread scale and compact design speed up routine calibration and bitheight changes. Function, compatibility, and performance Function: measures and sets workpiece or tool height for accurate cutting depths and consistent results. Compatibility: ideal for routers, router tables, milling machines, and other workshop equipment that require precise height control. Performance: repeatable accuracy ±0.01 mm across the 3–26 mm range; clear royal/metric scale for quick conversion and readout. Practical use scenarios Router bit height adjustment: set router bit to the exact cutting height before a pass to ensure consistent groove depth or profile detail. Table cut calibration: check and finetune the height of tablemounted tools and jigs to maintain uniform cut depth across multiple boards. Milling machine setup: confirm end mill height and workpiece offsets when switching tools or preparing precise milling operations. Who this is for Professional woodworkers calibrating equipment. DIYers upgrading accuracy on router tables and small mills. Anyone who needs a compact, accurate gauge for repetitive heightsetting tasks. What you get A compact, accurate aluminum height gauge with a clear royal/metric scale, 3–26 mm measuring range, and ±0.01 mm tolerance — built for fast, reliable setup and calibration in the workshop.
