American Standard 1/2 blind hole taps
The FT104 is a professional-grade spiral flute tap specifically designed for high-efficiency tapping of ANSI/ASME B1.1 standard threads. It's a tool for efficient and precise machining of internal threads in blind holes, effectively improving machining speed, thread accuracy, and tool life. It not only enhances machining efficiency and thread quality but also reduces machining costs. It is particularly suitable for applications in the automotive, aerospace, machinery, and hydraulic industries where high metric or imperial thread accuracy is required. It performs exceptionally well in high-efficiency machining and with complex materials. The spiral flute design of the spiral cutting tap effectively ejects chips upwards (for blind holes) or downwards (for through holes), preventing chip clogging, improving machining efficiency, and reducing thread damage. Suitable for rust-resistant and acid-resistant materials – austenitic stainless steel; ferritic and martensitic stainless steel; pure titanium; nickel alloys; and pure copper. It can be used with tapping spindles with axial compensation (conventional thread cutting) or for rigid tapping.

Design details engineered for accuracy, tool life and process stability.
Grinded using a high-precision thread grinder, the thread profile accuracy is controlled within ±0.01mm, and the thread surface finish can reach below Ra0.4μm, ensuring the accuracy of ANSI standard threaded connections.
Coatings such as TiAlN, TiCN, TAD, TiN, and DLC are available, with a maximum coating hardness of HV3400 and a friction coefficient as low as 0.15. Tool life is extended by 2-3 times compared to uncoated taps.
High-speed steel (HSS) and high-performance high-speed steel (HSSE) base materials, combining high toughness and red hardness, suitable for tapping general-purpose materials such as steel and aluminum alloys.
Chip removal direction is opposite to the tapping direction, increasing chip removal efficiency by 40% compared to straight flute taps, effectively preventing chip clogging, and is especially suitable for blind hole tapping.
Suitable for harder materials.
Suitable for processing soft or highly ductile materials.
High-performance helical cutting taps significantly improve production efficiency and quality in scenarios with high requirements for machining speed, thread accuracy, and tool life, especially in automated machine tools and CNC machining centers.
Effectively prevents tap breakage or thread surface defects caused by chip clogging, improving machining reliability.
In blind hole machining, it prevents chip accumulation at the bottom of the hole, improving machining efficiency and quality.
The helical flute structure performs excellently in chip removal and cutting processes in deep threaded holes.
