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

As a specialized NPT 14TPI external thread milling insert, it delivers unmatched efficiency with multi-tooth design. The WTM coating ensures long tool life in tough materials, while VARGUS’s precision grinding guarantees accurate thread dimensions and superior surface finish. A cost-effective upgrade from single-point turning for high-volume NPT threading.
