Handheld Electrode Punch can only accommodate round shapes up to Φ26.00mm and square shapes up to 22.00mm.
For punching sizes larger than these, the desktop punching jig Clean Press can handle round shapes up to Φ50.00 mm and square shapes up to 50.00 x 70.00 mm.

Introducing CLEAN PRESS,
a desktop precision punching jig for electrodes [5:40 silent]

Round handheld punches with the following sizes can be delivered immediately. Please contact us using the form below for stock status.

Φ1.00 to 26.00 mm in 1 mm increments, Φ11.28 mm
*Clearance 4μm, alloy tool steel, no blade coating

For example, if you specify a punching diameter other than the above, such as Φ9.5 mm, or if you order a square handheld punch, the product will be build to order and the delivery time will be 5 weeks or longer. Please contact us for details.

Yes, we can lend you a demo machine (Φ10.00 mm, clearance 4μm specification) free of charge so that you can check the usability and processing quality of the Handheld Punch.

We have a service in which you can send your materials to us and have us carry out test processing (for a fee).
Our laboratory engineer will punch out your materials and compile a report, and then we will return the punched products and material scraps to you.

Yes, we have experience with successfully processing several types of all-solid-state battery materials in the past.

We also offer such tools as the punching jig and the cut surface finishing jig for cross-sectional observation samples, particularly for brittle materials that would be shattered by processing with handheld punches.

Please contact us using the form below with any information or questions you may have.

Yes, all of our products are priced in JPY (Japanese Yen), but we will quote the payment amount in US dollars or euros at the exchange rate at the time we receive your quote request.

We recommend periodic cleaning (greasing) depending on the frequency of use. A maintenance kit is included with the product. For usage instructions, please refer to the included instruction manual.

During use, if the sliding feeling is getting rougher and/or the lever becomes difficult to return by itself, please contact us immediately before things get worse.

The warranty period for each product is one year from the date of delivery.

The clearance (gap on one side) between the punch (upper blade) and die (lower blade) can be specified as 4 μm, 3 μm, or 2 μm to best-fit the material properties and required processing quality (*).

A judgement exemplified in specifications selection
Workpiece: Typical cathode/anode electrode material with the total thickness of 300 μm or less
Quality standard: “No burrs by visual inspection”
[Recommended specifications]
→ Clearance 4 μm

*All products in stock are 4 μm specifications. 3- and 2-μm specifications are build to order.

Yes, it is possible if it is related to secondary batteries or needs for advanced material development (such as ultra-precision sample preparation for cross-sectional observation).

Depending on your needs, we can also assign engineers to work with you on a problem-solving project. Please feel free to contact us.
