INSIZE 6891-3 Magnetic V-Block Set 150x50x100 mm

INSIZE's 6891-3 magnetic V-block set is a matched pair of larger blocks, 150x50x100 mm each, with a built-in magnet and switch lever, holding a round shaft from 6 to 125 mm during inspection on a surface plate. INSIZE rates the magnetic force at 21 kgf and hardens the blocks to HRB70. As with the smaller 6891-1, INSIZE states this set is for inspection only, not for machining, because the magnetic force is comparatively low. Parallelism of the V-groove to the bottom and back faces is held to 10 micrometres, and the pair is matched in height to within 10 micrometres.
