What this tool does: a multifunction fishbonestyle aluminum height gauge that fits common woodworking and router tools, streamlining setup and measurement tasks. Why you need it: the fishbone structure accommodates multiple tool sizes (5' to 12'), so you can measure and repeat settings across bits, cutters, and fences without juggling multiple gauges. This reduces setup time and improves consistency in cuts. Key features and materials: Lightweight, anodized aluminum construction resists deformation while holding precise settings. Clear royal/metric scale for quick, visible readings. Accuracyengineered measurement range from 3 to 26 mm with ±0.01 mm tolerance for fine adjustments. How it solves problems: Eliminates guesswork when setting router bit height or aligning a milling cutter by providing repeatable, accuracy measurements. Durable anodized finish keeps the scale readable and the gauge true, reducing drift and rework over time. Fishbone design supports multiple tool diameters and profiles, so one gauge works for many operations. Performance and compatibility: Fits tools and setups that require measurements in the 5'–12' size band. Suitable for router tables, table cuts, and milling machines used in garages or professional woodshops. Practical use scenarios: 1. Set a router bit height on a router table to match an existing profile for consistent edge work. 2. Adjust a table saw or fence for repeatable rabbets and dadoes where exact depth matters. 3. Finetune milling machine cutter height during small production runs or prototype work to maintain tolerancecritical dimensions. Benefit summary: a compact, robust, and accurate measurement aid that saves setup time, improves repeatability, and adapts to multiple tool sizes—ideal for both hobbyist and professional woodworking environments.
