The Right Knife for Every Herbold Machine
Herbold machines use three main knife styles, each with a specific role in the cutting chamber. We stock precision-ground replacements for all three types and can help you find the right fit for your machine.
Crown Cutter Knives
Crown Cutter knives compatible with Herbold granulators and shredders that require specialized cutting geometry. Made from hardened tool steel, they hold their edge under continuous throughput demands and are available in multiple sizes to fit your specific machine.

Built for Herbold Machine Tolerances
Our replacement knives are precision-ground to match the dimensional specifications of Herbold machines. Proper fit means consistent cutting gaps, reduced vibration, and predictable machine behavior shift after shift.
Precision-Ground to Spec
Every knife is ground to tight dimensional tolerances. Correct sizing is critical — even small deviations in the cutting gap affect granulate quality, increase fines, and put extra load on the motor.

Why Knife Quality Matters
The knife is the highest-wear component in any granulator or shredder. Using the wrong replacement costs more than the savings suggest.
Low-quality replacement knives often lack the hardness and edge retention needed for demanding applications, leading to faster dulling and more frequent regrinding cycles.
Dimensional tolerances that are even slightly off can widen the cutting gap, reducing granulate quality and increasing fines in your output.
Substandard knives require more motor energy to achieve the same throughput, raising operating costs over time across your Low Speed or Central Granulator.
Knives that do not fit correctly create uneven wear on the rotor and cutting chamber, shortening the service life of other machine components.
Precision-ground, correctly-spec'd replacement knives from Virtus Equipment Direct are an investment in uptime, output quality, and machine longevity.
