Groz Surface Marking Block

A fully hardened and ground base which serves as an accurate reference surface. A machined Vee groove in the base allows the gauge to be used conveniently on curved surfaces. A Vee groove at the front end allows the spindle to adjust to any angle above or below the base allowing it to be used as a height gauge and also as a depth gauge. Two retractable pins allow the gauge to be located against the edge of a surface plate or T-slot for linear work. A 1/4 (6.35 mm) hole in the spring loaded scriber holder allows a dial indicator to be attached conveniently making the gauge useful for checking flatness parallelism heights depths etc. Grooves on the side of the base allow for comfortable grip. Well tapered scriber for better sighting while working. The scriber tip is hardened to 55-60 HRC Base Dimensions: 2-3/16 x 1-5/8 (55 x 40mm) Spindle Length: 7 inch with extra 4 inch spindle (175mm with extra 100mm spindle) Scriber Length: 3 inch (75mm)
