Ultimate Rotary Punch

Our Top of the Line Rotary Diecutting Punch – The Ultimate Rotary Punch brings a new standard to rotary diecutting. The punch is “Rotary Friendly”, no more rocking, less tearing of the stock, and less damage to the dieboard or anvil blankets.

The special features include Inside serrated bevel that aids in self ejection, allowing the slug to “pop” right out.  Alignment marks indicate radius for Proper insertion. Flex slots allow a snug, accurate fit. Beveled bottom eases insertion into the die.

The results using an Ultimate Rotary Punch are outstanding compared to a standard serrated punch. There’s less tearing and damage to the stock as shown here.

Why settle for a standard rotary punch when you can have an Ultimate Rotary Punch?
