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 30,000 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.
