Sandvik 266LL-160000-300-BG H13A

Group K — Cast iron

1. Grey iron (HB ≤ 240)
   Vc: 120–280 m/min; f: 0.15–0.50 mm/rev; ap ≤ 4.0 mm
2. Ductile / nodular iron (HB 200–300)
   Vc: 100–220 m/min; f: 0.12–0.40 mm/rev; ap ≤ 3.0 mm

Dry or minimal coolant works; mind the entry impact.

Group N — Aluminium & non-ferrous

1. Aluminium / Al-Si alloys
   Vc: 400–1200 m/min; f: 0.05–0.30 mm/rev; ap ≤ 5.0 mm
2. Copper / brass
   Vc: 200–500 m/min; f: 0.08–0.30 mm/rev; ap ≤ 3.0 mm

Sharp positive rake, polished face; use PCD for high-silicon aluminium.

Group S — Superalloys & titanium

1. Fe / Ni / Co-based superalloys
   Vc: 25–60 m/min; f: 0.08–0.20 mm/rev; ap ≤ 1.5 mm
2. Titanium alloys (e.g. Ti-6Al-4V)
   Vc: 40–90 m/min; f: 0.08–0.20 mm/rev; ap ≤ 2.0 mm

High-pressure coolant; keep a sharp edge and never dwell in the cut.
