INSIZE 6887-4 V-Block Set 125x44x69 mm

INSIZE's 6887-4 is the largest set in its V-Block Sets range: two hardened tool-steel blocks, 125x44x69mm each. Every block carries three V-grooves of different sizes: the largest handles shafts from 3 to 87mm, with two smaller grooves covering 3-34mm and 3-50mm 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.
