ER25 6 mm Collet Tool Holder

ER25 6 mm Collet Tool Holder

Industrial Automation Components | Superior Performance Series

Product Overview

The ER25 6 mm Collet is an essential component engineered for industrial automation, specifically for CNC milling, turning, and multi-axis machining centers. It is designed to secure cutting tools with high precision and rigidity. By minimizing axial runout, this collet plays a critical role in maintaining the geometric accuracy and surface finish of machined parts. It effectively dampens vibrations even at high speeds, extending tool life and optimizing material removal performance.

Manufactured in full compliance with DIN 6499 / ISO 15488 international standards, this collet offers universal interchangeability with standard ER collet systems. It is crafted from high-carbon alloy tool steel (65Mn or equivalent) and subjected to precise heat treatment processes to achieve a core hardness of HRC 44-48. This ensures high wear resistance, impact strength, and thermal stability. For more mechanical components, please visit our mechanical parts category.

Key Advantages

• High Runout Accuracy (≤ 5 Microns): Minimizes deviation from the rotation axis, ensuring balanced contact between the cutting edge and the workpiece. This reduces micro-burrs and vibration marks, significantly improving surface quality.
• Optimized Clamping Mechanism: Designed with a 0.5 mm clamping range, it ensures uniform surface contact, preventing tool slippage under high torque and aggressive cutting conditions.
• Superior Material Science: The high-carbon alloy steel construction ensures the collet maintains its integrity under thermal stress and mechanical loads, preventing deformation during high-speed operations.
