CAT50 ER16 Precision Collet Chucks
CAT50 ER16 precision collet chucks hold round-shank cutting tools in CNC machining centers equipped with CAT50 spindles. The ER16 collet system provides secure, concentric tool clamping for milling, drilling, reaming and finishing. These holders are precision balanced to G2.5 at 25,000 RPM. Select from 5 projection lengths (4, 6, 8, 10, 12 inches) to match tool reach and clearance requirements. Check the comparison chart for dimensions and specifications for each available holder.

Applications
- Ideal for high-speed CNC milling, drilling, reaming, and finishing operations requiring exceptional accuracy and repeatability.
- Precision ER collet system provides superior gripping force with excellent concentricity to improve surface finish and extend cutting tool life.
- Perfect for carbide end mills, drills, reamers, and other round shank tooling where minimal runout is critical.
- Through-spindle coolant capability delivers coolant directly to the cutting zone for improved chip evacuation, cooler cutting temperatures, and longer tool life.
- Precision balanced to G2.5 at 25,000 RPM for smooth, vibration-free machining in high-speed applications.
- Wide ER collet clamping range allows one holder to accommodate multiple tool diameters, reducing tooling inventory and setup time.
- High gripping force minimizes tool pullout during aggressive roughing while maintaining outstanding accuracy for finish machining.
- Manufactured for demanding CNC machining centers where tight tolerances, consistent repeatability, and maximum spindle performance are required.
- Excellent choice for production machining, prototype work, mold making, aerospace, automotive, and precision manufacturing applications.
- Designed to maximize spindle accuracy, improve part quality, and reduce scrap by maintaining exceptional tool concentricity throughout the machining process.
