DIN Extended Spiral Flute Taps

Wilson class DIN Extended Spiral Flute Taps are mainly used for machining threads of step holes and ultra deep holes, suitable for fields such as aerospace industry, automotive manufacturing, motorcycle engine production, refrigerator compressor manufacturing, mold industry, etc. that require high precision and quality in thread machining.

Product features

1.Structural design with outstanding chip removal efficiency

Adopting a spiral groove streamlined structure, the principle of fluid mechanics is used to guide the chips to be discharged in a directional manner along the groove, effectively avoiding the problem of chip accumulation in the chip storage groove. Especially for deep hole machining or easily clogged working conditions, process optimization by shortening the working length of the cutting edge can significantly reduce the probability of chip jamming and increase the service life of the tap by more than 30%.

2.Precision guarantee for blind hole thread machining

Capable of forming threads at the bottom of blind holes, the front end of the tool is designed to penetrate deep into the bottom of the hole to complete cutting, ensuring that the threads are machined to the maximum depth of the hole. After actual testing, the diameter error of the processed thread is controlled within ± 0.02mm, and the clarity of the tooth profile meets the Ra1.6 μ m surface roughness standard, meeting the requirements of high-precision assembly.

3.Enhanced cutting adaptability of multiple materials

The surface is treated with nitriding hardening or PVD coating process modification to form a dense wear-resistant protective layer, which has the characteristics of fatigue resistance, corrosion resistance, and high temperature stability. In the processing of non-ferrous metals such as alloy steel, austenitic stainless steel, and copper aluminum, it can withstand cutting forces of over 1500N and maintain the sharpness of the cutting tool during continuous processing.
