SK collet

Product overview
SK precision collets are designed for applications where torque transfer limits conventional ER systems. Their geometry increases torque output to approximately 1.5× that of standard ER collets while maintaining stable clamping accuracy. They provide corrosion resistance and low deformation under clamping load.

Features

• Approximately 1.5× torque output versus standard ER collets
• Stable clamping accuracy under torque load
• Corrosion-resistant materials and surface treatment
• Low deformation during clamping
• Geometry optimized for improved torque transfer

Applications

• Designed for CNC tool holder applications where torque transfer limits ER systems
• Suitable as a high-torque alternative to ER collets in milling, drilling and boring operations
