ER20 TSC Sealed Collet Set (25 Pcs.) - Inch

Designed for use with tooling and spindles that allow high-pressure coolant through the tool. These TSC Imperial collets have true nominal inch bores, minimizing compression for maximum concentricity and minimum runout. All collets are precision ground for less than 0.0003 in. (8 microns) of indicated runout. Each collet is cryogenically treated to -190° F to increase service life. During manufacturing each collet is subjected to multiple in-process quality checks culminating with 100% radial runout and precision deviation testing according to the DIN64499BD standard.

• Total runout less than 0.0003 in. (8 microns)
• These collets are designed for use with coolant thru spindle-equipped machines and tooling
• For use with coolant pressures up to 3,600 PSI (25MPa)
• Made from high-quality 65Mn spring steel steel, fully hardened (HRC44-48) and cryogenically treated
• All critical surfaces are precision ground for accurate fit
• Works in all ER20 Collet Chucks
• These collets have a 0.007 in. (0.2mm) range of collapse while maintaining full accuracy
