VARGUS R26E14WTM Multi-Tooth Comb Design 14 TPI NPT Thread Milling Insert with WTM Grade Coating
The VARGUS R26E14WTM is an external, multi-tooth (comb) thread milling insert from Israel’s VARGUS (VARDEX) TM series, designed for high-efficiency NPT thread milling on CNC machining centers. Optimized for 14 TPI NPT external threads with a 26mm nominal diameter, it features a precision multi-tooth profile and WTM grade coating, enabling one-pass threading, low vibration, and excellent surface finish in carbon/alloy steels, stainless steels, and cast iron. Ideal for mass production of pipe and fitting components.
- Multi-Tooth Comb Design: Multiple cutting teeth for one-pass thread milling, 3–5x faster than single-tooth tools.
- External (E) Orientation: Dedicated for external NPT threads; compatible with VARGUS TM26W tool holders.
- 14 TPI NPT Profile: Precision-ground to NPT 60° pipe thread standard (14 threads per inch).
- 26mm Nominal Diameter (R26): Matches standard TM26W tooling for rigid clamping and high stability.
- WTM Grade: PVD-coated (Ti,Al)N grade with high wear resistance and oxidation stability for dry machining.
- Chip-Effective Geometry: Optimized flute design for smooth chip evacuation, reducing tool wear and workpiece scorching.
- High Rigidity: Sintered carbide substrate with high hardness, resists chipping in interrupted cuts.
- Carbon steels (1045, S355, Q235, A105)
- Alloy steels (4140, 42CrMo4, HRC <45)
- Stainless steels (304, 316, 321, 420)
- Cast iron (HT200, HT250, ductile iron)
- Non-ferrous metals (aluminum, brass, light cuts)
- External NPT thread milling (14 TPI, 26mm diameter)
- Pipe and fitting manufacturing (oil, gas, hydraulic systems)
- High-volume production on CNC machining centers
- Continuous or light interrupted thread milling
- Replaces single-point turning for higher efficiency
- Automotive, aerospace, and general engineering parts
