Description and Features

Precision Collets: Swiss Type CNC Collet and Comprehensive Workholding Solutions

AVASTEC collet portfolio is engineered to deliver the ultimate gripping force and exceptional concentricity required for all precision machining operations. From micro-machining on sliding headstock lathes to heavy-duty turning and milling, our high-tension collets ensure stable and accurate clamping. By virtually eliminating bar push-back and radial runout, a high-quality Swiss type cnc collet directly improves the surface finish and dimensional accuracy of your components.

Main and Sub Spindle Collets for Swiss Machining

To support the demanding requirements of medical, aerospace, automotive, and electronics manufacturing, we offer a comprehensive variety of Main and Sub Spindle Collets compatible with all major Swiss lathe brands (Star, Citizen, Tsugami, Tornos, etc.). This lineup features the highly precise F type Pens (collets) designed for flawless bar feeding:

  • Standard F-Type Collets: Industry models including 1212E (F16), 136E/138E (F20), 145E (F25), and 161E (F32) for everyday precision turning.
  • Large Capacity Collets: Robust solutions like 1536E (F37), 173E (F48), and 185E (F66) engineered for handling larger bar diameters with zero slippage.
  • Specialized & TRAUB Profiles: Precision collets explicitly tailored for specialized machine requirements, including the 171E (F42-36 TRAUB) series.

Broad Range of Industrial Lathe and Milling Collets

Beyond sliding headstock applications, AVASTEC provides an extensive selection of standard workholding collets for conventional lathes, CNC turning centers, and milling machines. Our expanded inventory includes solutions for every machining scenario:

  • 5C Workholding Solutions: We supply the industry-standard 5c collet for reliable gripping in toolroom lathes and fixtures. For customized operations, our soft, machinable 5c emergency collet allows operators to bore precise shapes and depths. Additionally, the 5c expanding collet provides secure internal gripping for ID (Inside Diameter) holding applications.
  • High-Capacity Lathe Collets: For heavier bar stock and larger turning centers, we offer the highly rigid 16c collet and the heavy-duty 3j collet, delivering superior clamping force and preventing part push-back during aggressive cutting.
  • Precision Milling & Small Lathe Collets: Our inventory covers the ubiquitous r8 collet, essential for manual and CNC knee mills, as well as 3c collets designed for smaller, high-precision instrument lathes.

Maximize Your Machining Performance and Tool Life

Manufactured from premium-grade spring steel and subjected to rigorous heat-treatment processes, all AVASTEC collets provide superior wear resistance and a prolonged lifecycle. The optimized slot geometry and ultra-precision ground contact surfaces deliver uniform clamping pressure across the workpiece. This high-tension grip minimizes machining vibrations, ensuring repeatable accuracy and continuous reliability even in high-volume production environments.
