A Diamond Collet is a specialty Workholding collet designed with a diamond-coated or diamond-grit gripping surface to provide exceptional grip, extreme wear resistance, and long service life.
It is used where standard steel collets slip or wear quickly, especially in high-volume, smooth, or hardened material applications.
Key Features
💎 Diamond-coated gripping surface
🔒 Extremely high friction – zero slippage
🛡️ Outstanding wear & abrasion resistance
🎯 Maintains accuracy over long production runs
🛠️ Reduced collet replacement frequency
⚙️ Suitable for automation & mass production
