Materials & inserts: Uncoated, sharp-edge CCGT/DCGT/WCGT carbide inserts give a keen cutting edge and low cutting forces in aluminum, brass and other non-ferrous metals; positive rake angles and built‑in chipbreakers minimise built‑up edge and deliver smooth chip flow.
Holder lineup & sizes: Includes eight 3/4' × 3/4' indexable holders—QA12R-30C cut‑off/groove, SER0750B16 threading, SCLCR12-3B right-hand, SCLCL12-3B left-hand, SDNCN12-3B for 62.5° turning, SWGCR12-3B 90° turning, SDCGR12-3B 45° turning, SCBCR12-3B 75° turning—plus a 3/4' × 12' S12S-SCLCR3 boring bar.
Operations & applications: Designed for turning, facing, taper turning, chamfering, external and face grooving, parting and 60° threading, as well as internal boring; each insert has multiple cutting edges that can be indexed when an edge becomes dull.
Machine compatibility & users: Sized for manual or CNC engine lathes with approximately 10–16' swing over the bed; compatible with standard quick‑change tool posts; intended for machinists, prototype shops and manufacturing engineers working primarily with non‑ferrous materials.
Set contents & extras: Ships as a complete kit with eight holders and a boring bar, aluminium‑geometry inserts installed, 10 extra inserts (GTN‑3LH, 16ER A60‑LH, CCGT32.51‑LH, DCGT32.51‑LH, WCGT32.52‑AF), insert screws, keys, a 6' 4R stainless ruler and a fitted aluminium case; replacement insert kit 3988-0034INSERTS extends service life.
