RobbJack TS-201 2-flute stub length Tuffy grade carbide end mill

Stub-length Tuffy grade square end mills in 2, 3, and 4 flute — short, rigid general-purpose cutters offered in five coating options.

  • Square end stub-length Tuffy grade carbide in three flute counts: TS-201 (2 flute), TS-301 (3 flute), TS-401 (4 flute), all with 30° helix
  • Stub flute lengths for rigidity — e.g. 1/4" diameter carries only a 1/2" flute length on a 2" OAL
  • Inch sizes 1/16"–3/4" (2 and 4 flute; 3 flute runs 1/16"–1/2"); metric MTS-401 4 flute covers 2–20 mm
  • Five coating options across the line: Uncoated, TiN, TiCN, AlTiN, and Diamond-Like Carbon (DLC) — ordered by suffix (-T, -C, -A, -DLC)
  • 2 and 3 flute rated for slotting, side milling, and helical interpolation; 4 flute optimized for side milling
  • Broad material range: aluminum, copper, titanium, magnesium, cast iron, steel, brass (plus wood on 2/3 flute)
  • High-performance roughing, semi-finishing, and finishing — dry, wet, cold air, or spray mist
  • Tolerances: cutting dia +.000/−.002 (1/16"–1/4") and +.000/−.003 (5/16"–3/4"); shank −.0001/−.0002; MTS cutting dia +.000/−.075 mm
