ER25 12 mm Collet Tool Holder

ER25 12 mm Collet Tool Holder

The ER25 12 mm Collet is a precision mechanical component engineered for the secure integration of cylindrical shank cutting tools into spindles. It ensures high radial and axial rigidity, which is critical for maintaining geometric accuracy and surface finish in industrial automation and precision machining.

Technical Overview

This premium-grade collet utilizes a conical outer surface that, when tightened by a nut, deforms its flexible segments to center and grip the 12 mm tool firmly. This system minimizes runout, extends tool life, and optimizes surface finish in CNC milling, turning, and drilling operations. Manufactured from high-strength alloy steel, it offers excellent wear resistance and toughness, maintaining its elasticity through repeated clamping cycles.

Key Advantages

• Ultra-Low Runout: Engineered for precision, this collet minimizes radial runout, ensuring balanced contact between the cutting tool and the workpiece. This is essential for high-speed machining (HSM) and tight-tolerance applications.
• High Clamping Force: The optimized conical geometry provides uniform, powerful clamping, preventing tool slippage or axial movement during heavy-duty operations.
• Vibration Damping: The material structure and segment design effectively dampen high-frequency vibrations, reducing chatter marks and protecting the cutting edges of your tools.
