A Double Cone Collet is a precision collet with two tapered surfaces (front & rear cones) that provide uniform radial clamping.
This design ensures high concentricity, strong grip, and minimal runout, making it ideal for tool holding and work holding where accuracy is critical.
🔹 KEY FEATURES
Dual taper for balanced & uniform clamping
Excellent concentricity (low 10micron TIR)
High gripping force with less distortion
Long service life
Suitable for high-speed and precision operations
