INSIZE 6887-1 V-Block Set 50x19x24 mm

INSIZE's 6887-1 V-block set pairs two hardened tool-steel blocks, 50x19x24mm each, so you can hold a round shaft steady for inspection or machining on a surface plate. Every block carries three V-grooves of different sizes: the largest handles shafts from 3 to 32mm, with two smaller grooves covering 3-16mm and 3-22mm for slimmer round stock, all starting from a 3 mm minimum. INSIZE keeps the three grooves parallel to the top and bottom faces to within 5 micrometres, and matches the height of the two blocks in the set to within 5 micrometres, so the pair stays level end for end.
