ER Collet
What is an ER Collet?
ER collet is an extremely versatile tool holding system and an indispensable core component in CNC machining centers, milling machines, engraving machines, and other precision equipment. Its primary function lies in its tapered design with flexible slots, which securely and accurately holds tools such as drills, end mills, and taps of various shank diameters in the spindle or tool holder. This ensures stability and high concentricity throughout the machining process.
Advantages of Our ER Collet Products
- High Precision and Concentricity: Each of our ER collets is made from top-quality spring steel and goes through precise grinding and strict heat treatment processes to guarantee extremely low runout. This significantly improves machining accuracy and surface finish while effectively extending the lifespan of your tooling.
- Powerful Clamping Force and Stability: Optimized slot design delivers strong, uniform clamping force, securely holding the tool to prevent slip or vibration even during high-speed cutting and heavy-duty machining.
- Comprehensive Range, One-Stop Solution: We offer the industry’s most complete ER collet series—from ER8, ER11, ER16 for precision engraving, ER20, ER25, ER32 widely used in mold making, to ER40 for heavy-duty machining. All sizes comply with the international DIN6499 standard, meeting all the needs of your machines and applications.
- Exceptional Durability: Selected materials and advanced surface treatments provide outstanding wear and fatigue resistance, enabling repeated, long-term, and high-frequency operations—making our collet the most cost-effective choice for you.
Applications
Our ER collets are widely used in CNC machining centers, precision lathes, drilling machines, engraving and milling machines, woodworking equipment, and various precision automation industries. They are ideal for machine tool manufacturers, hardware parts production, and mechanical subcontractors for bulk procurement.
