Genuine Coventry dieheads and Coventry dies have become a by-word for external threading. Originally developed by Alfred Herbert and sold world-wide, the Coventry diehead is probably used in more countries than any other system.
Namco Tooling provides a range of products and services for Axial and Tangential thread rolling. We have a full range of Rolling Heads for every application including Winter rolls and Wagner rolls.
Versotool & Cleveland Dieheads are chosen for high volume production, the dies typically last 50 times longer than other brand dies, making them the first choice for those industries where unit costs are critical.
