Toolholders & Collets

A high quality collet is desirable when it comes to precision machining of small parts for the medical and aerospace industries. For a quality part that meets high-precision specifications, you need a burr-free collet with guaranteed concentricity. This collet would be finish ground to provide a smooth and concentric gripping area (order hole) for the bar stock or work piece.
