High Precision ER16 Collets

ER16 Collet
High-Precision Tool Holding for CNC Spindles & ATC Systems

Overview
This high-precision ER16 collet is built for reliable, repeatable tool holding in CNC spindle and ATC applications. Precision-ground and hardened for consistent clamping force and low runout, it helps improve cut quality, tool life, and overall machine performance.

Why It Matters

• Helps reduce tool runout
• Improves cut quality and tool life
• Maintains consistent grip at high RPM
• Supports repeatable tool holding

Performance

• Runout Accuracy: ±0.0002" (±0.005mm)
• Designed for high-speed spindle use
• Balanced for stable operation at elevated RPM

Compatible Systems

• ER16 spindle motors
• Manual tool change setups
• ATC systems

Best Practices

• Match collet size exactly to the tool shank
• Clean the collet and nut before installation
• Replace worn collets as needed
• Avoid overtightening

Specifications

• Collet Type: ER16
• Material: Hardened, precision-ground steel
• Application: CNC routing, carving, and machining

Notes

• Collets are consumable precision components
• Collet condition affects cut quality and spindle health
