40 mm / 1.57 in Eyelet Punching Die for Large Grommet Hole Preparation KLP0066DEL

40 mm / 1.57 in Eyelet Punching Die for Large Grommet Hole Preparation

This Eyelet Punching Die prepares the material opening required before installing compatible large grommets in the 40 mm / 1.57 in inner diameter group. It supports cleaner hole preparation on tarpaulins, tents, curtains, awnings, banners, vinyl prints, technical textiles, leather and reinforced fabric products.

The product is designed for the hole-preparation stage only. It does not set the grommet, close the washer or form the grommet barrel. Final installation must be completed with a compatible Eyelet Setting Die.

What This Tool Does

• Prepares the material opening before large grommet installation.
• Helps create a cleaner and more centered hole in compatible materials.
• Supports repeated workshop applications when used with compatible equipment.

What This Tool Does Not Do

• It does not install the grommet.
• It does not close the washer.
• It does not replace a grommet setting die.
• It does not include eyelets, washers, adapters or press equipment.

Compatible Applications

Use this punching die before installing compatible 40 mm / 1.57 in large grommets. The finished visible opening is not the only compatibility factor. Check the capsule diameter, barrel height, washer form and material thickness before production.

Different stainless, galvanized, steel, brass or coated large grommet systems may have different capsule and washer geometry even when the visible opening is similar.

Suitable Materials

• Truck tarpaulins and protective covers
• Tents, awnings, shade structures and outdoor textiles
• Curtains and large textile panels
• Banners, vinyl prints and advertising displays
• Technical textiles and coated fabrics
• Leather, faux leather, bags and cover applications

Equipment Compatibility

Use this die with physically compatible hand tools, impact tools, manual presses, electric machines or pneumatic machines. 1/4 in and M6 connection options are different thread standards and must not be treated as interchangeable.

Check holder geometry, thread diameter, thread pitch, seating surface and alignment before use. An adapter may be required when machine and die standards differ.

Application Sequence

1. Select the compatible large grommet and washer.
2. Check capsule geometry, washer size, barrel height and material stack.
3. Mark the grommet position on the material.
4. Fit the punching die into compatible equipment.
5. Prepare the material opening with centered pressure.
6. Inspect the cut edge and material deformation.
7. Place the grommet and washer into the prepared opening.
8. Complete installation with a separate Eyelet Setting Die.
