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)
