Details & specifications

Genuine Rhin-O-Tuff OEM interchangeable punch dies for the Onyx HD-7725 punch. Select your binding pattern below: coil, wire, comb, VeloBind and specialty patterns available. Mid-State Litho stocks OEM dies and replaces dies rather than sharpening them, so your punch stays in tolerance.

How to choose the right die pattern

This punch takes interchangeable dies, so you buy the pattern that matches the binding style your bindery runs (die prices on this page range from $1,228 to $1,514). Four things identify the die you need:

  • Binding style: Coil (spiral), Twin-Loop Wire, Plastic Comb, or VeloBind. Pick the style that matches the elements your finishing line uses.
  • Pitch: holes per inch, shown as 2.5:1, 3:1, 4:1, or 5:1. Coil and wire follow different pitch conventions, so match the number to your current pattern.
  • Hole shape: Round or Oval, depending on the element and look you want.
  • Diameter: for coil dies, the hole size (for example 4mm, 5mm, or 6mm).

If you are not sure which pattern you run today, tell us your machine and current element and we will confirm the SKU.

Why buy your dies from Mid-State Litho

  • Authorized Rhin-O-Tuff dealer. These are genuine OEM dies, not aftermarket clones.
  • Replace, do not sharpen. We supply fresh OEM dies so your punch stays in tolerance; worn or reground dies drift out of spec.
  • Phone support to match your pattern. Tell us your machine and current pattern and we confirm the right SKU.
  • Ships from an authorized US dealer.

Frequently asked questions

Which die pattern do I need for my Onyx HD-7725?
Identify your current pattern by hole shape and pitch, then match it to the Die Pattern selector on this page (coil 2.5:1 / 3:1 / 4:1 / 5:1, wire 2:1 / 3:1, comb, or VeloBind). If you are unsure, call us with your machine and current element and we confirm the SKU.

Are these genuine OEM Rhin-O-Tuff dies?
Yes. These are OEM dies, not aftermarket, and Mid-State Litho is an authorized Rhin-O-Tuff dealer.

Do these fit any Onyx punch, or only the Onyx HD-7725?
Dies are model-specific. This page lists only dies compatible with the Onyx HD-7725; see the die pages linked above for other Rhin-O-Tuff punches.

Can I run more than one binding pattern?
Yes. The Onyx HD-7725 is an interchangeable-die punch. Buy additional patterns and swap them as your jobs require.

Do you sharpen dies or replace them?
We replace dies rather than sharpening them, so the punch stays in tolerance. A worn or reground die drifts out of spec.
