  • 2. Interactive Design

    • With straight flute design, you can ensure smooth cutting and efficient chip removal during threading operations. Reduces clogging by 25% compared to helical flute taps*.

  • 3. Performance Parameters

    • With multiple sizes (1/8 to 1/2 inch), you can accommodate diverse threading needs across different pipe diameters. Covers 80% of standard pipe threading tasks*.

  • 4. Scenario Solutions

    • Designed for both home workshops and commercial metalworking, you can create precise NPT threads efficiently in diverse environments. Suitable for intermittent and continuous use*.

  • 5. Certification Standards

    • Certified to NPT threading standards (ANSI/ASME B1.20.1), you can ensure seamless compatibility with standard pipe fittings and industry requirements. Meets global metalworking compliance criteria*.

Product details

Hss Tin Taper Pipe Interrupted Thread Teeth Npt Hand Taps 1/8 1/4 3/8 1/2

The HSS Tin Taper Pipe Interrupted Thread Teeth NPT Hand Taps are precision-engineered tools designed for creating NPT (National Pipe Thread) threads in metal components. Crafted from high-speed steel (HSS) with a tin coating, these taps combine durability, corrosion resistance, and smooth cutting action. Available in sizes 1/8, 1/4, 3/8, and 1/2, they cater to a variety of industrial and manufacturing applications.

Supplier's note

  1. Technical Breakthroughs:

    • Interrupted Thread Teeth: Reduces chip buildup by 40% compared to straight-flute designs, enabling smoother threading in deep bores.
    • Tin Coating: Achieves 20% lower friction than uncoated HSS taps, extending tool life in corrosive environments.
    • NPT Thread Geometry: Ensures 100% leak-proof seals in pressurized systems, surpassing ANSI B1.20.1 standards.

  2. Version Selection Guide:

    • Base Model: Ideal for occasional use in standard metalworking (e.g., plumbing repairs). Its HSS construction balances cost and durability.
    • Advanced Model: Suitable for medium-volume production (e.g., automotive assembly lines). The carbide coating enhances resistance to wear in stainless steel.
    • Pro Model: Best for high-precision, high-volume applications (e.g., aerospace manufacturing). The diamond-like coating withstands extreme temperatures and achieves micron-level tolerances.

With the Pro Model’s diamond-like coating, you can achieve thread precision up to ±0.001", ensuring flawless fits in critical aerospace components. The Advanced Model’s 200 RPM capability allows 33% faster threading than the Base Model, optimizing productivity in medium-scale operations.
