Collet
Collets are precision tool-holding devices designed to securely clamp cutting tools or workpieces with high concentricity and minimal runout. Typically made from hardened spring steel, collets are cylindrical in shape with segmented slots that compress tightly when inserted into a compatible collet chuck or holder. This provides uniform clamping force, reducing vibration and ensuring accurate machining. Collets are essential in high-speed CNC machining, milling, drilling, and turning operations where precision and tool stability are critical.
Applications
- Used for holding drills, end mills, taps, reamers, and other rotating tools.
- Common in CNC machines, lathes, VMCs, and engraving machines.
- Also used in workpiece holding for turning and grinding applications.
- Widely applied in aerospace, automotive, mold & die, medical, and general machining industries.
Key Features
- Made from high-tensile spring steel or hardened alloy steel.
- Provides excellent grip and runout accuracy (typically < 0.005 mm).
- Available in standard systems like ER, R8, TG, OZ, SK, and DA collets.
- Offers quick-change capability for efficient tool swaps.
- Ensures low vibration, improving surface finish and tool life.
- Available in metric and imperial sizes, in both slotted and sealed types.
- Suitable for high-speed machining and fine precision work.
