The G5 Tooling 531424C is a new CAT40 ER32 collet chuck with a 3.13" (79.5 mm) gage length, designed for use in CAT40-spindle CNC machining centers. The CAT40 taper shank conforms to ANSI/ASME V-flange toolholder standards and features the dual drive slots and retention knob thread (7/16-20) characteristic of the V-flange system; the ER32 collet nose accepts ER32-series collets with a clamping range of 1–20 mm (up to 3/4" in inch collets). The body carries a black oxide/nitride surface treatment visible in the photos, and the precision-ground gage surface and collet nose are left in bright finish for dimensional accuracy. This holder is suited for milling, drilling, reaming, and tapping operations on CAT40 VMCs; ER32 collets must be sourced separately. Part number 531424C is confirmed on the G5 Tooling label visible on the packaging; the barcode reads 531424.
