HSS Tap

GP115 High-Efficiency Tapered Pipe Thread Taps

Pipe Thread Extrusion Tap

HSS / HSS-E / HSS-E-PMTiN coating

The GP115 is a professional-grade forming tap designed for chipless tapping of pipe threads according to GB/T 7306-200 standard. During processing, the material undergoes cold working, resulting in a denser and smoother thread surface, reducing surface roughness and improving thread performance. It significantly improves machining quality and production efficiency, especially with hard materials, precision workpieces, or complex processes. It is particularly suitable for applications in the automotive, aerospace, machinery, and hydraulic industries where high precision of metric or imperial threads is required. It performs exceptionally well in high-efficiency machining and with complex materials. Because there is no cutting process, the threads produced by the forming tap are burr-free, making it suitable for workpieces requiring high surface quality.

Engineering Features

Design details engineered for accuracy, tool life and process stability.

GB/T 7306-200 Standard Pipe Thread Profile

Utilizing a high-precision thread grinder, the thread profile accuracy is controlled within ±0.01mm, and the thread surface finish can reach below Ra0.2μm. The thread connection strength is increased by 20% compared to cutting taps, ensuring reliable sealing performance.

Chipless Extrusion Machining Principle

Threads are formed by plastic deformation of the workpiece material through extrusion, generating no chips and avoiding chip clogging and workpiece scratches. This is especially suitable for tapping blind holes in pipe threads.

HSS/HSSE Base Material

High-speed steel (HSS) and high-performance high-speed steel (HSSE) base materials, combining high toughness and red hardness, suitable for tapping general-purpose plastic materials such as aluminum alloys and low-carbon steel pipes.

Spindle-free extrusion machining principle

Threads are formed by plastic deformation of the workpiece material through extrusion, without the generation of chips, avoiding chip clogging and workpiece scratches, especially suitable for blind hole tapping.

Extrusion taps hold a vital position in modern manufacturing due to their advantages such as high-quality thread formation, increased strength, long tool life, and chipless machining. They are particularly advantageous in scenarios requiring high efficiency, environmental friendliness, and high precision machining.

Due to the lower cutting force, the required amount of lubricant is usually lower, further reducing pollution and costs in production.

In blind hole machining, it prevents chip accumulation at the bottom of the hole, improving machining efficiency and quality.

Extrusion tapping produces no cutting waste, reducing environmental impact and making it more environmentally friendly.
