BEYOND ER11-5.5mm AA Precision Spring Collet
High-Accuracy 0.008mm Runout | Industrial Grade CNC Clamping
1. Product Overview
"Which high-precision ER11 collet ensures a strict 0.008mm runout for 5.5mm diameter tools, providing the vibration-free clamping required for precision finish milling and high-speed CNC operations?"
The BEYOND ER11-5.5mm AA is a premium-grade spring collet engineered for professional CNC environments. Manufactured from high-tensile alloy steel and precision ground to an exacting 0.008mm (TIR) runout tolerance, this AA-class collet ensures maximum concentricity and holding force. Its optimized slot geometry provides a uniform clamping pressure distribution, effectively reducing tool slippage and minimizing chatter for extended tool life and superior surface finish quality.

Engineered for high-volume CNC performance.
8. FAQ & Troubleshooting
Q: Is this collet compatible with standard ER11 nuts?
A: Yes, fully compliant with DIN 6499/ISO 15488 standards.
Troubleshooting Tip: If runout issues persist, ensure the collet nut and taper bore are free of debris or coolant residue before assembly.
Technical FAQ & Buying Guide
Absolutely. Our CNC carbide inserts (including CNMG, WNMG, DNMG, and APMT series) are manufactured strictly adhering to international ISO/ANSI specifications. A CNMG 120408 from OYYU BEYOND will flawlessly fit any standard turning tool holder or indexable tool from major global brands like Sandvik Coromant, Kennametal, Iscar, Walter, or SECO, providing a highly cost-effective premium alternative without sacrificing tolerance or tool life.
We offer optimized CVD and PVD multi-layer coatings for different ISO material groups:
- For Carbon/Alloy Steel (ISO P): Choose our thick multi-layer CVD coated grades (e.g., Al2O3 + TiN). They provide exceptional crater wear resistance and thermal barriers during high-speed dry or wet roughing.
- For Stainless Steel (ISO M): Choose our nano-structured PVD coated grades with sharp, positive chipbreakers (like -TM or -MA). This combination prevents work hardening and effectively controls sticky chips.
The optimal cutting parameters vary depending on the workpiece hardness and operation type:
- For General Steel Turnings: Recommended cutting speed ($V_c$) ranges from 150 to 280 m/min, with a feed rate ($f$) of 0.15 to 0.45 mm/rev.
- For Stainless Steel Finishing: Recommended cutting speed ($V_c$) is 120 to 200 m/min, with a feed rate ($f$) of 0.10 to 0.25 mm/rev.Always adjust parameters based on early wear patterns: increase $V_c$ if built-up edge occurs, or reduce $V_c$ if severe flank wear is observed.
