TaeguTec VNGG160401 ML TT5080 Carbide Turning Insert – Rhombic 35°, R0.1, ML chipbreaker VNGG330

1) Group M: Stainless Steel (304 / 316 / Ferritic / Martensitic)

1. Ferritic / Martensitic stainless steel (HB ≤ 220)
   Vc: 100–180 m/min; f: 0.08–0.22 mm/rev; ap ≤ 2.0 mm
2. Austenitic 304 / 316 (prone to work hardening)
   Vc: 70–140 m/min; f: 0.06–0.18 mm/rev; roughing ap ≤ 1.5 mm, finishing ap 0.2–0.8 mm

Sufficient water-soluble cutting fluid must be supplied throughout machining to avoid edge chipping caused by work hardening.

2) Group S: Superalloys & Titanium Alloys

1. Iron-based superalloys (HB ≤ 280)
   Vc: 40–160 m/min; f: 0.06–0.15 mm/rev; ap ≤ 1.2 mm
2. Nickel / Cobalt-based superalloys (annealed / aged)
   Vc: 30–100 m/min; f: 0.05–0.12 mm/rev; ap ≤ 1.0 mm
3. Titanium alloys
   Vc: 110–200 m/min; f: 0.07–0.16 mm/rev; ap ≤ 1.8 mm

3) Secondary Group P: Low-carbon Mild Steel (Light Finishing Only)

Vc: 120–200 m/min; f: 0.10–0.20 mm/rev; ap ≤ 1.2 mm
