Accurate and versatile fixture for round, square, and hex-shaped workpieces (ideal for secondary operations on screw-machine parts). Uses standard 5C collets, including step collets for large diameters, expanding collets for ID clamping, and emergency collets for special shapes. Can be mounted vertically or horizontally. Height-adjustment assembly is removable for through-feeding. Available in two types: single collet and triple collet. The triple-collet version, shown here, clamps three workpieces close together in a single unit. This version has two locating holes that match up with the standard 2.0000" hole spacing of our modular-fixturing tooling plates.
