If you own the James Burn Alpha-Doc® MK4 automatic punching machine, then we know you hold quality finishing in the highest regards. To achieve the perfect quality punched holes for your book binding needs, your punching dies need to be incredibly sharp. With dull punch die pins, the edges of the holes could not only be rough (which can cause trouble binding/finishing the documents, as well as quality control issues that could harm your business:customer relationships), but they will also cause undue wear to the die casing itself, as well as potentially your expensive equipment investment. With dull dies, your machine has to work harder to power through pages, which can sometimes lead to expensive repairs, and even replacement.

Leave worry behind and buy new Alpha-Doc® MK4 punching dies online today. They are manufacturer-direct OEM punch binding dies that are made of the highest quality materials, including incredibly strong die tool steel that is built to last. When the punching pins begin to dull, send the dies to us for an official James Burn Express Die Sharpening service to extend their life even further.

We stock a large variety of punching patterns for the most popular document binding methods, and can even manufacture custom-made dies to meet your exact specifications. Just call (866) 537-2244 or email for a custom die quote.

Keeping several punching dies on hand is recommended for several reasons. For one, it means that when you send your primary die off for sharpening, or if it needs to be replaced, there is never any down time, which means you will never loose any business by being without the proper tools. Keeping more dies on hand also opens the door to new business, as you will never again have to tell potential customers "sorry, we can't do that" -- instead, you will be able to say, "yes, we can absolutely help you" no matter what their punch pattern needs are (remember, we can custom-make dies for your specific needs if you need a non-stocked pattern).

When you pair your premium James Burn Alpha-Doc® MK4 automatic punch machine with these OEM dies made to the highest quality standards, you are guaranteed to produce the best punched documents in the business. Don't settle for less; buy your Alpha-Doc® dies online today, or call (866) 537-2244 for a custom die quote.
