Eyelet Punching Die for 8–8.5 mm / 0.31–0.33 in Inner Diameter Eyelets KLP00050DEL

Eyelet Punching Die for 8–8.5 mm Inner Diameter Eyelets

This Eyelet Punching Die is used to prepare material before compatible eyelets with an 8–8.5 mm / 0.31–0.33 in finished inner diameter are installed. It helps create the opening required for the eyelet barrel to pass through leather, synthetic leather, fabric, canvas, webbing, tarpaulin and similar materials.

This is a Punching Die, not an Eyelet Setting Die. It prepares the material but does not roll the barrel, lock the washer or complete eyelet installation.

Compatible 8–8.5 mm Inner Diameter Range

This tool can be used for hole preparation in compatible eyelet systems with a finished inner diameter from approximately 8 mm / 0.31 in to 8.5 mm / 0.33 in.

The prepared hole and the finished inner opening of an installed eyelet are different measurements. The hole is created to allow the eyelet barrel to pass through the material. The inner diameter is the visible opening that remains after final setting.

A compatible Eyelet Setting Die may tolerate small dimensional differences within this range during practical installation. Final compatibility still depends on barrel outside diameter, barrel height, washer construction, material thickness and the exact setting surface.

Punching and Eyelet Setting Are Separate Steps

1. Prepare the material with this Eyelet Punching Die.
2. Check that the eyelet barrel passes through the material cleanly.
3. Position the eyelet and washer where required.
4. Use a separate matching Eyelet Setting Die.
5. Inspect the installed eyelet for rotation, looseness, cracking or material distortion.

Compatibility Checks Before Production

• Finished inner diameter of the selected eyelet
• Actual barrel outside diameter and barrel height
• Washer type and reverse-side construction
• Total thickness of the material stack
• Shape of the Eyelet Setting Die
• Press-holder and die-connection compatibility

Suitable Materials and Applications

• Leather goods, wallets, bags and cases
• Belts, straps, webbing and canvas assemblies
• Tarpaulin, tent, awning and outdoor textile work
• Garment, footwear and accessory details
• Labels, cardboard, craft and sample-making projects
• Repair, workshop and small-batch production work

Press Compatibility

Use this die with a physically compatible hand press, bench press or stable hand-tool setup. The available M6 and 1/4 in options identify die-connection standards and must be checked against the actual holder.

M6 and 1/4 in threads are not automatically interchangeable. Confirm thread diameter, pitch and press alignment before ordering or installing the die.

Frequently Asked Questions

What eyelet range is this Punching Die for?

It is used for hole preparation before compatible eyelets with an 8–8.5 mm / 0.31–0.33 in finished inner diameter are installed.

Does this tool install the eyelet?

No. It prepares the hole only. Use a separate matching Eyelet Setting Die for final installation.

Can one setting system work with both 8 mm and 8.5 mm inner diameter eyelets?

A compatible Eyelet Setting Die can tolerate small differences in some practical applications. Confirm the eyelet barrel, washer, material thickness and die surface together before production.

Is the prepared hole the same measurement as the finished inner diameter?

No. The prepared hole allows the barrel to pass through the material. The finished inner diameter is the visible opening after the eyelet is installed.

Can it be used on leather and tarpaulin?

Yes, when the press setup and cutting pressure are suitable. Sample testing is important for thick, stiff or multilayer materials.

Does the package include the press or setting die?

No. The product is supplied as the punching-die set only. Presses, setting dies and eyelets are separate items.
