Carbide Spiral Point Tap

  • Carbide Tipped Taps for Cast Iron Gray Ductile Iron Threading Tools

    Carbide Tipped Taps for Cast Iron Gray Ductile Iron Threading Tools

    Carbide Tipped Taps are specially designed for abrasive cast iron machining including gray iron & ductile iron. With premium brazed carbide tips, optimized flute geometry and stable performance, they deliver 5–10× longer tool life than HSS taps, higher cutting speeds and consistent precision threads for mass production.

  • Universal Carbide Point Tap for Steel & Stainless Steel Threading

    Universal Carbide Point Tap for Steel & Stainless Steel Threading

    The Universal Carbide Point Tap is an internal threading tool manufactured from cemented carbide (tungsten steel), designed for quick and accurate thread start-up in through-holes or shallow threaded holes. Its pointed chamfer geometry allows the tap to enter the hole easily and start cutting threads in a controlled manner. It can be used as the first tap in a sequential tap set, or on its own where full thread depth is not required.

  • Internal Cooling Solid Carbide Point Taps  for CNC Machining Centers

    Internal Cooling Solid Carbide Point Taps for CNC Machining Centers

    Internal Cooling Solid Carbide Point Taps are engineered for CNC machining centers with high-pressure Through-Spindle Coolant (TSC) systems. They solve key pain points in difficult-to-machine materials: chip clogging, tap breakage, poor thread quality, and short tool life—delivering flawless internal threads for aerospace, automotive, medical, and high-end manufacturing.
