Why buyers pick this one
- Dual Precision Options
- Choose between standard high precision (≤ 0.008mm) or ultra-precision (≤ 0.005mm) to perfectly match your machining requirements and budget. Better concentricity means longer tool life and superior surface finishes.
- Premium 65Mn Spring Steel
- Through advanced heat treatment and cold-drawing, our 65Mn steel achieves a surface hardness of HRC 44-48. This ensures the collet springs back to its original shape over thousands of tool changes without metal fatigue.
- Wide Clamping Collapse
- The slotted elastic design allows each collet to collapse and clamp securely over a 1mm range (for larger sizes), reducing the total number of collets needed in your inventory.
- Universal DIN 6499 Compatibility
- Guaranteed to fit perfectly into any standard ER collet chuck, ER nut, or ER-equipped driven toolholder on CNC lathes and milling centers worldwide.
- Dedicated B2B OEM Solutions
- We empower global distributors. Request custom clamping ranges, bespoke laser engraving, and specific packaging (individual plastic tubes or customized multi-piece cases) to build your brand.
