    Vise

    Indexer with Workpiece

    Transform your machine vise into an indexing system in seconds. These indexers help you position round workpieces at precise, repeatable angles for machining flats, hexes, and key slots. Slide them onto the end of a workpiece and secure with the set screw. These indexers attach directly to your workpiece, so you can move them from setup to setup without losing your reference point. These indexers are etched with graduation marks up to 360° so you can line up your workpiece with a machinist square. A hex, square, and octagon are cut into the face, so you don’t need to check the graduations for 45°, 60°, or 90° increments.
