    V-Blocks for Magnetic Workholding

    Image of Product. Front orientation. V-Blocks. V-Blocks for Magnetic Workholding.
    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.
    Sold as Matched Pair—Matched pair blocks are ground together, so their heights, faces, and grooves are identical. When you rest your workpiece across the two blocks, they keep the centerline level.
