21 mm / 0.83 in Eyelet Punching Die KLP0032DEL

Dedicated Hole Preparation for 21 mm Flat Brass Eyelets

This Grommet Punching Die is produced for use before installing the 21 mm / 0.83 in flat brass eyelet. It helps prepare the required round opening on tarpaulins, curtains, tents, awnings, banners, canvas and suitable technical textile surfaces.

The matching eyelet has a 31.8 mm / 1.25 in outer diameter and a 4.7 mm / 0.19 in barrel height. If you use this specific flat brass eyelet and want to manage hole preparation as a separate, controlled production step, this is the correct tool group to choose.

What Does the Punching Die Do?

The die prepares the opening through which the eyelet barrel will pass. A correctly prepared hole helps the eyelet sit more evenly on the material and supports better alignment during the later setting operation.

This product does not set the eyelet and washer. After punching, a compatible Eyelet Setting Die must be used to complete the installation.

When Should You Choose This Die?

Choose this die when you are working with the specified 21 mm / 0.83 in flat brass eyelet and require a dedicated tool for preparing the opening before setting. It is especially useful for workshops that repeatedly install large eyelets on tarpaulins, curtains, tents and technical textile products.

Do not select the die only by a local trade size. Actual inner diameter, outer diameter, barrel height and eyelet construction should be checked. Other eyelet profiles can be compared under Flat Brass Eyelets.

Press and Machine Compatibility

The die connection must match the selected press or punching machine. Compatibility with a particular hand press, impact press, electric machine or pneumatic system should be confirmed before ordering.

Material thickness, coating and number of layers can affect the punching result. Test the actual production material before starting repeat production.
