KeyKnife Chipper Package

The Rotochopper KeyKnife Chipper Package makes it quick and easy to switch from grinding to chipping by swapping out the grinder tooth mounts with knife mounts.

Grind & Chip with a Single Machine

We collaborated with KeyKnife to make it simple for our customers to diversify into chipping markets without a complex conversion kit or a second machine. The KeyKnife Chipper Package is a bolt-in option that works with the standard patented Replaceable Mount Rotor for the Rotochopper B-66,  B-66 E, and FP-66.

Quick & Easy Conversion

A single operator can switch from grinder teeth to chipper knives quickly and easily with no rod pullers or other specialized tools. It’s as easy as two bolts per knife mount and two bolts per knife clamp.

Simplified Maintenance & Operation

A KeyKnife insert uses significantly less steel than a traditional chipper knife, making handling and replacement easier. The chipper blade on each mount is much narrower than traditional chipper knives, helping to minimize the maintenance costs resulting from rocks, metal, and other contaminants.

"Unlike other grinder to chipper conversion packages, the Rotochopper KeyKnife™ system is simple, reliable and adds more flexibility to our B66. Because this system is simple, there are fewer problems the operator has to deal with when downtime occurs. Also, with this system we can add more value-added products to our line of products made with our B66."
