Main types of Coventry Die Head

Coventry die head


Shank is spring loaded. Can be used on automatic or manual machines.

Closed by handle or can be fitted with spring band auto die closer for use on automatic machinery.


Ch type

Shank is solid to body. More suitable for manual operation but can be used on automatic machinery.


Dx type

For use on manual and automatic machinery.

Will open in the same way as CHS and CH die heads by ‘pull off’ action.

Can also be opened by ‘pushing open’ using the plunger mechanism. This prevents stripping when producing small diameter threads in soft materials. Also ensures more accurate thread lengths
