Crush Cut Dies
We invented the solid hardened rotary die in the late 1960s by creating a wedge-type cutting edge on a solid cylinder through the use of EDM (electric discharge machining). Our proprietary process allows us to precisely manufacture dies, thereby achieving high-quality cuts at high speeds for countless materials and products.
We make our crush cut rotary dies from solid tool steel, assuring an exceptional level of hardness and longevity. We manufacture these dies to exacting tolerances in order to ensure a precise cut, smooth die rotation, and consistently accurate results.
Reasons to Use Crush Cut Dies:
- Capable of extremely high-speed operation
- Machine sharpening
- Fully-hardened, solid steel construction for strength and longevity
- Dies can be partially or fully segmented
- Capable of quick-changing
- Precise cutting shape tolerances
- Scrap stripping
Sharpening Crush Cut Dies
Each crush cut die produced at Bernal is durable enough to withstand multiple sharpenings throughout its die life. Each time we sharpen a Bernal crush cut die we bring it back to the same flawless quality it had when it left our facility, keeping it as precise and consistent as the day you installed it.
Partially or Fully Segmented Rotary Dies
Our crush cut dies can feature specially designed segments and removable rings to accommodate a wide variety of applications and enable selective repair of high wear areas. In addition to cutting, these partial or fully segmented dies are also perfectly suited to embossing and laminating. The removable segments turn a generic carton die into a fully customizable solution for several end-users simply by changing customer specific segments in the die, spreading the cost justification of a single die set over multiple customers and applications.
High-precision machining techniques are essential to producing dies with exceptionally long life-spans. Our Advanced Machining Lab with a climate controlled environment ensures that your die is manufactured to the highest standards, using CAD/CAM, CNC and CMM inspection.

Flexible vs. Solid Rotary Dies. What’s the Difference?
There are two types of rotary dies: flexible and solid. Rotary die cutting involves either a flexible or solid rotary die. These dies are both cylindrical dies. A flexible die is made of a thin sheet of steel, and wraps around a magnetic cylinder. A solid die is a solid steel cylinder, and is traditionally used in more long run applications for extended die life. Bernal develops solid rotary dies for converting and product manufacturing applications throughout many industry sectors.
