Engineering Features

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

80° Pg Thread Forming Structure

Strictly adheres to DIN 40430 standards, meeting the sealing thread connection requirements of German standard electrical connectors. Thread formation is completed in a single pass, increasing machining efficiency by 40% compared to traditional taps.

Ultra-fine Grain Carbide Substrate

Utilizes HRC68 grade ultra-fine grain carbide, improving chipping resistance by 60% and enabling stable machining of electrical materials such as steel, aluminum alloys, and brass.

German Standard Precision Control

Thread pitch accuracy is controlled within ±0.005mm, and surface finish reaches Ra≤0.2μm, meeting the stringent tolerances and sealing requirements of electrical equipment.

Enhanced coating adhesion

Utilizing vacuum ion plating, coating adhesion is improved by 40%, preventing coating peeling and ensuring machining accuracy.

Using a thickened, equal-diameter shank body, rigidity is increased by 25%, eliminating runout during high-speed machining and ensuring consistent thread depth and accuracy.

The direct action of cutting fluid reduces friction between the cutting edge and the workpiece, improving surface finish and reducing tap wear.

The cutting edge radius is precisely controlled at 0.003mm, balancing sharpness and wear resistance, reducing edge chipping, and guaranteeing consistent machining.

An eccentric cutting design eliminates the need for pre-drilling a center hole, allowing direct machining of blind holes and threads, reducing processes and improving efficiency.
