Durable probe and body: quenched at temperature to produce a hard probe with wear and impact resistance; made from aluminium alloy dipstick to ensure long service life as a table saw gauge. Clear digital display: digital direct reading function with a vivid display; a shockproof dial provides durable performance and helps maintain work efficiency. Easy to use: sliding head design allows user activated length adjustment and prevents lateral movement after locking; this delivers improved stability and precision with every cut. precision measurements: measuring range 010 mm in 0.01 mm increments; rotating measuring ring enables quick calibration to obtain accurate measurements quickly and easily in any position. Practical details: aluminium alloy construction designed for reliable table saw use and precise measurement tasks. Use scenarios Repetitive stop settings on a table saw: set the length with the sliding head, lock, and read the measurement directly for consistent cuts. Stock thickness and shim checks during setup: measure material or shims to confirm blade height or dado depth settings. Onthefly calibration across positions: use the rotating measuring ring for fast, inposition calibration to maintain accuracy during complex cuts.
