Diamond Drawing Die

Our Diamond Drawing Die is a premium-grade tool engineered for the most demanding wire drawing applications, where extreme precision, surface finish, and longevity are essential. Utilizing either natural diamond or high-quality polycrystalline diamond (PCD) inserts precisely mounted in a durable tungsten carbide or steel housing, this die delivers unmatched wear resistance and dimensional stability—even when processing hard or abrasive materials at high speeds.

Ideal for drawing fine to ultra-fine wires made of copper, aluminum, gold, silver, platinum, stainless steel, and specialty alloys, the Diamond Drawing Die ensures consistent wire diameter, superior roundness, and an exceptionally smooth surface finish. The diamond bore maintains its geometry over extended production runs, significantly reducing downtime for die changes and minimizing material waste.

Thanks to diamond’s unparalleled hardness and thermal conductivity, these dies excel in high-volume, high-precision industries such as electrical cable manufacturing, microelectronics, medical device fabrication, and aerospace. They are especially suited for applications requiring sub-micron tolerances and flawless wire integrity.

Available in single-hole or multi-hole configurations with custom inlet angles, bearing lengths, and exit geometries, our Diamond Drawing Dies are tailored to your specific process parameters. Backed by stringent quality control and advanced metrology, they represent the ultimate solution for manufacturers seeking maximum productivity, reliability, and wire quality in critical drawing operations.
