In modern precision machining, the performance of tool-holding accessories directly affects machining accuracy, stability and production efficiency. Our newly launched ER32 and ER40 high-precision collets are specially designed for CNC milling machines, machining centers, drilling and tapping machines, providing reliable clamping solutions for various metal processing scenarios.
Product Features
Superior Machining Accuracy：Adopting precision grinding and strict quality control, these collets deliver high concentricity and stable clamping accuracy, effectively reducing runout, ensuring smooth workpiece surface and improving overall processing quality.
Wide Clamping Range：ER32 collets support a clamping range from 2mm to 20mm, while ER40 collets cover 3mm to 26mm. They are compatible with various cutting tools, end mills, drills and taps, meeting diversified processing requirements.
High Strength & Durability：Manufactured from high-grade alloy steel with heat treatment, the collets feature high elasticity, wear resistance and long service life. They maintain strong clamping force even under high-speed and long-term operation.
Strong Compatibility：Widely used in CNC milling machines, vertical machining centers, drilling machines, tapping machines and other CNC equipment. Suitable for mold manufacturing, auto parts processing, hardware processing and other industrial fields.
Daily Maintenance & Service Life Suggestions
To ensure stable clamping accuracy and extend service life, proper daily maintenance is highly recommended.
Clean the collet surface, inner hole and nut thread regularly to remove chips, cutting fluid residue and dust.
Lubricate the thread and contact surface appropriately before installation to avoid jamming or uneven stress.
Avoid over-tightening or forced assembly, which may cause deformation and reduce clamping precision.
For daily production environments, it is suggested to inspect the collet every 3–6 months. If obvious wear, elastic fatigue, cracks or decreased clamping accuracy appear, replace the collet in time to ensure processing quality and operational safety.
Application Value
With stable performance and easy installation, ER32 & ER40 collets help reduce tool loosening and wear, improve processing efficiency, and lower production downtime. They are essential high-performance accessories for machine tool users and machining workshops pursuing high efficiency and precision.
