ER25 4 mm Collet Tool Holder

ER25 4 mm Collet Tool Holder

Industrial Automation Components | Premium Performance Series

The ER25 4 mm Collet is a critical component for modern machining, ensuring precise, stable, and reliable tool holding in CNC milling, turning, drilling, and reaming operations. By aligning the cutting tool perfectly with the spindle axis, this collet directly enhances machining accuracy. Its design utilizes a conical seat and a specialized clamping nut to exert uniform radial pressure, preventing tool slippage and vibration even at high speeds and feed rates.

Manufactured in accordance with DIN 6499/ISO 15488 standards, this collet offers broad compatibility across various industrial CNC machines. It is crafted from high-alloy tool steel, heat-treated to a hardness of HRC 58-62, ensuring exceptional wear resistance, elasticity, and deformation resistance. The precision-ground surface finish minimizes friction and maximizes clamping stability.

Key Advantages

• Superior Runout Accuracy (< 0.003 mm): Minimizes radial deviation, ensuring balanced contact between the cutting edge and the workpiece. This extends tool life, improves surface finish (Ra value), and ensures tight geometric tolerances.
• Standardized Compatibility: Fully compliant with DIN 6499/ISO 15488, allowing seamless integration with various CNC machining centers, milling machines, and lathes.
• Vibration Damping: The flexible segments and high-alloy steel construction effectively absorb vibrations, protecting both the tool and the workpiece during high-force operations.
