Manufactured from high grade tool steel fully hardened to 55-60 HRC.
Manufactured and numbered in matched pairs, each pair has two 90° Vees of different capacities which are identical to the Vees of its matching block. The Vee’s are ground central, parallel and square with the ends and sides.
These Vee Blocks are very useful for holding work securely during drilling, milling and grinding operations and also in layout and inspection work. Each pair of Vee Blocks comes complete with a pair of rigid and robust clamps.
Permissible Height difference between matched pairs – Within 0.0002" (5 microns).
Parallelism and Squareness of Vee grooves with respect to all surfaces – Within 0.0003" (8 microns).
Parallelism of opposite faces of Vee Blocks – Within 0.0003" (8 microns).
Squareness of adjacent exterior faces of Vee Blocks – Within 0.0003" (8 microns).
Flatness of Working Faces – Within 0.0002" (5 microns)
