Durable Build: Cobalt steel brings high hardness & heat resistance; spiral flutes clear chips smoothly. Sharp ground blades cut clean burr-free threads for tough metals (not for cast iron). Passivation boosts wear resistance, anti-oxidation and service life. Easy & Wide Application: Chamfered square shank for easy clamping; works on iron, steel & stainless steel with drill presses, tapping/CNC machines.Note: Not for handheld electric drills. Precision Sealing: Made to US thread standards, ideal for O-ring/gasket seal internal thread repair & production. Bright Finish: Smooth polished surface TiCN: Better wear & hardness than TiN TiN: Higher speed & wear resistance vs bright taps TaC: Hard, anti-stick, low friction for heavy-duty jobs
- Cobalt high speed steel (HSS-E), featuring excellent red hardness and heat resistance. The cobalt-infused material drastically reduces cutter wear when tapping stainless steel, carbon steel, brass and ductile iron
- Precision Spiral Taps ANSI NPT Parallel Pipe thread standard, strict thread pitch and tooth contour guarantee precise female NPT internal threads. Add gasket / seal / O-ring to prevent leakage. Flange connections, oil plugs, pump flanges, and low-pressure pipe fittings are mechanically locked only.
- Spiral flute design realizes upward chip removal, efficiently pulls chips out of blind holes without clogging or tooth chipping. Ideal for blind hole tapping on valve body, flange, pump port, oil plug, elbow, tee and straight connector.
- Standard square shank fits drill presses, tapping machines and CNC equipment, compatible with both manual repair and industrial batch production. Widely applied in plumbing, hydraulic, fuel gas and sealed pipeline maintenance.
