This Interstate (P/N 63324156) 18-piece ER32 collet set covers the full inch fractional range from 3/32 in to 3/4 in in 1/16 in increments, stored in a black-painted wood box with foam-padded lid to protect collet faces during storage and transport. Each ER32 spring collet conforms to the DIN 6499 / ISO 15488 standard with a 32 mm body diameter and 8° included taper angle, providing a clamping range of 1 mm per collet and a nominal runout of ≤0.0002 in (5 µm) TIR at rated accuracy. The collets are manufactured from through-hardened alloy tool steel with a black-oxide finish and are compatible with any ER32-standard collet chuck — including milling machine spindles, CNC machining centers, lathes with ER32 chucks, and tapping heads. Condition is new — other (original retail packaging may be absent or opened, box shows shelf wear); collets retain their original protective film on several pieces as visible in photos. Increments included: 3/32, 1/8, 5/32, 3/16, 7/32, 1/4, 9/32, 5/16, 11/32, 3/8, 7/16, 1/2, 9/16, 5/8, 11/16, 3/4 in, plus two additional metric-range collets as typical for this set configuration.
