Rolling Wedge Milling Tools for Skidsteer Planer Attachments

A carbide pick is fixed in its holder and smashes into the pavement thousands of times a minute. A Rolling Wedge cutter turns as it works, using a rolling-wedge-lifting-cutting action that exploits the material's low tensile strength rather than fighting its compressive strength. Less resistance means less vibration, less heat and far less tool wear — which is why the tools last on the order of ten times longer between replacements.

Fixed picks impact the surface and rebound, sending chatter back through the drum, the hydraulics and the operator's seat. Because Rolling Wedge cutters roll across the material instead of striking it, that rebound never develops. It is the difference operators report first — many customers place a second order after a single day on the machine, purely on how the attachment feels to run.

Yes. The industry norm is a dedicated pick for each material — one for asphalt, another for concrete — which means someone has to change out every pick on the drum when the surface changes. Rolling Wedge cutters handle mixed-material surfaces with the same drum in a single pass, so asphalt patched with concrete does not stop the job.

Yes. In a documented field assessment on a 24-inch Caterpillar PC306B drum, Rolling Wedge tools milled a roadway joint straight through solid steel dowel bars, then continued on to mill additional concrete sections with the same tools — no change-out in between. Tool marks from the cut across the dowel bars are visible in the assessment photos.

In that same assessment, the drum carried 278 total cutting edges: 252 carbide teeth across 28 large 8.75-inch Rolling Wedge cutters, 18 across 2 small 2.50-inch cutters, and 8 carbide picks. After milling through the dowel bars and continuing into concrete, 3 cutting edges were damaged — 1.1% of the total. Two large cutters lost one tooth each (0.8%), the small cutters showed zero damage, and both affected cutters remained usable without replacement. The one carbide pick on the drum broke to the point of having no carbide left, a 12.5% failure rate on the pick population.

No cutting water is required. Because the tools are always turning instead of being impacted into the material, they do not build the heat that conventional systems manage with water. Water is only used where dust suppression is required on site.

Rolling Wedge tools typically need replacement every 1 to 3 months, compared to roughly twice a week for traditional carbide picks. A change-out takes about 20 minutes rather than 1 to 2 hours. That combination removes most of the maintenance downtime and tool-change labour from a high-volume milling operation.

Yes. Rolling Wedge milling drums and tools run on planer attachments fitted to both rubber-tire and track skidsteer loaders, as well as larger milling equipment including CAT and Roadtec machinery. Contractors can upgrade equipment they already own instead of buying new machines.

Rolling Wedge offers a two-week trial program for qualifying customers, so contractors and municipalities can run the system on real jobsites before committing. Contact Rolling Wedge directly at (309) 322-1600 to check eligibility and schedule a trial.
