HSS Tap

HP108 Spiral Flute HSS-E-PM Cutting Taps

Machine Taps

HSS-E-PMTiN coating

The HP108 is a professional-grade spiral flute tap specifically designed for high-efficiency tapping of metric threads according to GB/T 192-2003 standards. With its efficient chip removal, high precision, and high adaptability, it is an ideal choice for blind hole thread machining, particularly suitable for deep holes, high-toughness materials, and complex working conditions. This high-performance tool, designed specifically for thread machining, excels in high-efficiency machining and complex materials due to its spiral flute structure and cutting edge design. The spiral flute design discharges chips upwards along the flutes, preventing chip accumulation in the machining area, making it especially suitable for deep hole and blind hole thread machining. It significantly improves machining efficiency, reduces tool wear and machining costs, and is an important tool in modern thread machining.

Engineering Features

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

GB/T 192-2003 Standard Metric Tooth Profile

High-precision thread grinding is used, with tooth profile accuracy controlled within ±0.008mm. Thread surface finish can reach below Ra0.3μm, ensuring the accuracy of national standard threaded connections.

Multiple Coating Options

TiAlN, TiCN, TAD, TiN, DLC, and other coatings are available. Coating hardness reaches up to HV3400, and the coefficient of friction is as low as 0.15, extending tool life by 2-3 times compared to uncoated taps.

35° Optimized Helical Flutes

The chip removal direction is opposite to the tapping direction, improving chip removal efficiency by 45% compared to straight flute taps, effectively preventing chip clogging, especially suitable for tapping deep blind holes.

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 materials such as steel and aluminum alloys.

Spiral flute taps are suitable for various materials including steel, stainless steel, aluminum alloys, copper, and titanium alloys. When machining materials with high viscosity or toughness (such as stainless steel or titanium alloys), they effectively reduce cutting resistance and tool wear.

Effectively prevents tap breakage or thread surface defects caused by chip clogging, improving machining reliability.

In blind hole machining, it prevents chips from accumulating 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.
