Types of Thread Rolling Dies

A Wide Array of Proven, Essential Components

In a specialized industry, Tesker helps ensure your technical success by providing high-quality dies that are optimized for your equipment and your application. Here’s a brief overview of the types of dies we’ve been crafting for years. 

Annular Dies

A sampling of the options

• Flat Taper
• Form Ground Taper (FGT)
• Short Flat Taper
• Short Form Ground Taper
• Flat Taper Continuous
• Form Ground Taper Continuous
• Double Step-off

Infeed Dies

• Plunge rolling die with the helix angle ground into the die
• Used for general rolling of parts up to the length of the dies
• Work piece rotates between the dies, but has little or no axial movement

Speed-up Dies

• Increased productivity
• Commonly used for all threaded rods from ¼" to ¾" diameter

Helical Slow Feed Dies

• Reduce power requirements
• For high helix work where part of the helix angle is ground into the die and the spindles are tilted for the rest of the helix angle
• Feeds through at a slower rate, giving dies more time to form thread
