Usage
These inserts are ideal for a variety of turning and grooving applications where high precision and surface finish are critical. They perform exceptionally well in full‑radius grooving, multi‑directional turning, and parting operations up to .200″ stock thickness. The design allows the insert to cut flush to the collet face or shoulder of larger‑diameter workpieces, making it suitable for tight‑space machining and complex part geometries. Whether you are producing automotive components, aerospace parts, or general industrial hardware, the LGT040D2RFR provides reliable performance on both ferrous and non‑ferrous materials.
