Engineering Features

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

60° NPSF Dryseal Pipe Thread Geometry

Strictly adheres to the B1.20.3 standard, meeting the threading requirements for American Standard Dryseal pipe fittings; threads are formed in a single pass, boosting machining efficiency by 40% compared to traditional taps.

Precision Control to US Standards

Thread pitch accuracy is maintained within ±0.005mm, and surface finish reaches Ra ≤ 0.2μm, satisfying the stringent tolerance and sealing requirements of Dryseal pipe fittings.

Ultra-fine Grain Carbide Substrate

Utilizes HRC68-grade ultra-fine grain carbide with 60% higher chip resistance, ensuring stable machining of pipe fitting materials such as steel and stainless steel.

High-precision Cutting Edge Honing

The cutting edge radius is precisely controlled at 0.003mm, balancing sharpness with wear resistance to minimize edge chipping and ensure machining consistency.

Enhanced Coating Adhesion

Employs a vacuum ion plating process that increases coating adhesion by 40%, preventing coating delamination from compromising machining accuracy.

Direct application of cutting fluid reduces friction between the cutting edge and the workpiece, improving surface quality and reducing tap wear.

The cutting edge radius is precisely controlled at 0.003mm, balancing sharpness with wear resistance to minimize edge chipping and ensure machining consistency.

Features an eccentric cutting design that eliminates the need for pre-drilling center holes, allowing for direct threading of blind holes; this reduces process steps and increases efficiency.
