INSIZE 6887-3 V-Block Set 100x33x52 mm

For larger round stock, INSIZE's 6887-3 V-block set offers two hardened tool-steel blocks, 100x33x52mm each. Every block carries three V-grooves of different sizes: the largest handles shafts from 3 to 68mm, with two smaller grooves covering 3-26mm and 3-40mm 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.
