This TiN-coated solid carbide thread mill is precision-engineered for machining 1/4"-18 NPTF (National Pipe Taper Fuel) threads - the dry-seal variant of NPT used in critical fluid/gas systems. The gold-colored Titanium Nitride (TiN) coating enhances wear resistance while maintaining sharp cutting edges for superior thread quality.
- Thread Standard: 1/4"-18 NPTF (ANSI B1.20.3)
- Material: Micro-grain carbide substrate
- Coating: 2-3μm TiN layer (HV 2300+)
- Flute Design: 3-4 flutes (optimized for steel/iron) with 30° helix angle for smooth chip flow
- Dimensional Accuracy: Complies with ASME B94.19 with ±0.01mm runout tolerance
- Shank Options: 6mm/8mm/3/8" straight shank with Weldon flat available
For NPTF Applications:
- Maintains tight root/crest tolerances required for fuel/oil systems
- Prevents galling in stainless steel fittings
- Outperforms HSS taps by 3-5x life in 4140 steel
TiN Coating Benefits:
- Reduces friction coefficient by 40% vs uncoated
- Withstands 600°C intermittent heat
- Visible wear indication (coating discoloration)
- Hydraulic manifold blocks
- Compressed air systems
- Fuel injection components
- API 6A wellhead equipment
