At Best Cutting Die, we have a wide range of reliable tools and parts, including:




Our flexible envelope converting dies work with all models of W&D and F.L. Smithe envelope machines. We also offer special chrome plating to extend the die’s life span and improve its cutting power.

We make and recondition high dies for a range of standard and nonstandard envelope shapes.

We custom design our magnetic cylinders, so they’re compatible with our flexible dies to streamline your envelope converting equipment.




We have rotary window gummers available for next-day delivery and a selection of in-house panel dies ready for same-day delivery. We test the quality of our segment dies and gummers using settings that mimic production conditions.

Our range of side knives and accessories ensures you’re completely prepared for every aspect of envelope converting.

Our innovative embossing units can elevate your products and give them an element of distinction. We design our embossers for fast setups to speed up your manufacturing process and maximize employee time.
