Product Details
Industrial ER Spring Collet Series (0.005mm/0.008mm Precision)
The Universal Standard for High-Precision CNC Tool Clamping
Secure your cutting tools with unwavering accuracy using the premium ER Spring Collets from Shanghai Daoge Xiaoman Tools Co., Ltd. Built to the globally recognized DIN 6499 standard, our ER collets provide an exceptionally wide clamping range while maintaining superior concentricity. We utilize premium 65Mn spring steel, renowned for its incredible elastic memory and fatigue resistance. Whether you require our High-Precision (0.008mm TIR) line for general milling, or our Ultra-Precision (0.005mm TIR) line for micro-machining and fine finishing, we deliver absolute reliability. Stop buying mixed retail sets; partner with a direct OEM manufacturer to bulk-order the exact sizes you need (ER11 through ER40) with your proprietary brand laser-etched on every piece.
Key Technical Advantages
- 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.
