We are offering steel products made from ms & en31 with 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. Accuracy is maintained within 5-8 microns
