High Speed Steel Threading Dies

Core Material & Performance: Crafted from high-speed steel (HSS), the threading dies feature excellent hardness, wear resistance and heat resistance, ensuring stable cutting performance and long service life during continuous thread processing, suitable for regular industrial threading operations on common metal workpieces.

Specialized Application: Exclusively designed for electric threading machines, the dies are precision-machined to match the spindle and feeding structure of electric threading equipment, enabling seamless assembly and smooth operation without additional adaptation, ideal for professional workshop and on-site construction threading work.

Specification Configuration: Supplied as a 4-piece set, with four practical size combinations available: 1/2"-3/4", 1"-2", 2.5"-4", covering the most commonly used thread dimensions in industrial and plumbing applications to meet diverse on-site processing needs.

Standard Thread Types: Compatible with two universal pipe thread standards—BSPT and NPT—the dies cut precise, standard tapered threads with clear tooth profiles, ensuring tight and reliable connection of pipe fittings, complying with industry thread manufacturing norms for good interchangeability.

Practical Design: The dies adopt a professional cutting tooth design with reasonable chip removal grooves, which facilitates smooth chip discharge during high-speed rotation, reduces cutting resistance and tooth blockage, and maintains consistent thread accuracy for repeated use.
