Use these inspection V-blocks to support rods, shafts, and other cylindrical workpieces for precise inspection or measuring tasks. The round surfaces reduce pressure on your workpiece, which helps prevent damage.

Support workpieces at the exact height you need for inspection, milling, or grinding. These V-blocks combine the precision of shims and blocks with the adjustability of a screw jack. They help you keep workpieces level, even when the ends are uneven. Turn a dial to move the surface of each block up or down in 0.001” increments, then lock it in place with a set screw. Made in pairs, these blocks are ground to tight tolerances for grooves that are centered and parallel with the base. They’re hardened iron for durability and dent resistance.

Set these V-blocks onto a magnetic chuck or plate to lock metal workpieces in place—no fussing with clamps or bolts. Made of alternating layers of iron and stainless steel, these blocks conduct the magnetic field through their body and channel it straight into your workpiece. They’re often used to cradle rods, shafts, and irregularly shaped parts during grinding and inspecting. Each layer is entirely fused together with copper brazing, so you can machine these blocks without the layers separating. Compared to blocks made from aluminum or brass, these blocks are harder and more dent-resistant, so they hold their shape over time.
