21 mm / 0.83 in Flat Brass Eyelet Hole Punching Die KLP0032DEL

A Dedicated Punching Die for Large Flat Brass Eyelets

This punching die is made for hole preparation before installing the 21 mm / 0.83 in flat brass eyelet. It gives canvas, tarpaulin, curtain, tent and technical textile workshops a dedicated tool for managing the first stage of eyelet installation.

The matching eyelet measures 31.8 mm / 1.25 in across the outside and has a 4.7 mm / 0.19 in barrel height. When this exact eyelet construction is used, selecting its dedicated punching die helps create a more consistent production workflow.

Why Hole Preparation Matters

The eyelet barrel must pass through the application surface before the washer and eyelet can be set. An irregular or incorrectly sized opening can affect alignment, surface coverage and the final setting operation.

This die prepares the round opening before installation. It does not close the eyelet or washer. A compatible Eyelet Setting Die is required for the second stage.

This Is a Punching Die, Not a Setting Die

Selection and Production Advice

Select this tool when the actual eyelet dimensions match the measurements listed above. Do not rely only on a local size number, as eyelets with similar names may have different inner diameters, barrel heights and body constructions.

Material thickness, coating and layer count can affect punching performance. Test the complete application on the real production material before repeat work. Other eyelet constructions are available under Eyelets and Grommets.
