Cylindrical / Machine Dies

CJWinter manufactures the premier line of machine dies and tooling.

We now manufacture both Helical and Annular machine dies in various styles for your thread rolling machine, including Through-Feed, Double-Taper, Speed-Up, Plunge, and Slow-Up.

CJWinter also offers overhung die holders and double support die holders for both straight threads and taper pipe threads.

Die Materials

D2

Moderate toughness and intermediate wear resistance. Supplied on dies for machine screw threads.

DC53

General-purpose cold work die offering twice the toughness of D2 with superior wear resistance and higher fatigue strength.

M2

High-speed steel with excellent toughness and wear resistance. Optimal for cold work dies.

M42

Super high-speed tool steel designed for machining high-strength and pre-hardened steels and nonferrous alloys. Ideal for aerospace and oil and gas industries.

Optional

Other materials available upon request. Contact us for details.

Edge Finish

Standard

30°, 45°, or 60° Chamfer Angles

Custom

R3 Radius Root Chamfer or Custom Chamfer Angles

When rolling, the recommended angle on each side of the blank diameter is 30° from the axis of the part.

A 30° chamfer will give an approximate 45°angle after rolling. For harder materials, a lower chamfer angle (25° to 28°) is preferred so thread roll life is not compromised.

To order a special chamfer or edge finish, please specify the chamfer angle and length.
