Coventry Dies & Dieheads
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.
