5-Pack CAT40 ER32 Collet Chuck Set | 40Cr Steel | 0.0002in Accuracy | 70mm Gage Length | 8000 RPM | Through-Coolant | CNC Milling & Lathe

Five CAT40 ER32 Holders. Production-Grade Accuracy.

A set of five CAT40 ER32 collet chucks machined from high-grade 40Cr steel, hardened and ground to deliver 0.0001-0.0002in (in tenths) accuracy and high concentricity for demanding CNC applications. The 2.75in (70mm) gage length suits a wide range of milling, turning, and drilling setups, and the V-flange CAT40 design supports through-spindle coolant from pull stud to collets — keeping tools cool and extending tool life in high-speed operations up to 8000 RPM. The fully ground flange and V-groove make tool changes fast and reduce wear on the spindle and tool changer. Single-piece construction with a polished rust-resistant finish. Production balanced to industrial standards. Pack of 5 — ideal for setting up multiple operations without constant tool changes.
