Materials & inserts: uncoated, sharp-edge CCGT/DCGT/WCGT carbide inserts for free-cutting performance in aluminum, brass and other non-ferrous metals; positive rake and chipbreaker geometry minimises built-up edge.
Holder lineup & sizes: includes eight 1" x 1" indexable holders—QA16R-40D cut-off/groove, SER1000D16 threading, SCLCR16-4D right-hand, SCLCL16-4D left-hand, SDNCN16-4D 62.5°, SWGCR16-4D 90°, SDCGR16-4D 45°, SCBCR16-4D 75°—plus a 1" x 12" S16T-SCLCR4 boring bar.
Operations & applications: supports turning, facing, tapering, chamfering, grooving, parting, 60° threading and boring; each insert features multiple edges for indexable use when a cutting edge dulls.
Machine compatibility & users: sized for manual or CNC engine lathes with a 13–20" swing; works with standard quick-change tool posts; ideal for machinists, prototype shops and manufacturing engineers cutting non-ferrous materials.
Contents & replacements: includes nine holders/internals with uncoated aluminum inserts plus extra inserts, screws, keys, a 6" 4R stainless ruler and a fitted aluminum case; replacement insert kit 3988-0001INSERTS and insert families CCGT432-LH, DCGT432-LH, WCGT432-LH, GTN‑4LH and 16ER A60-LH are available.
