Nozzle seems sharp enough but even with the cleaner running at full power the wood doesn't come out of the cut. Also, with the same cut as my original cutter, the cutter motor was put under a lot more stress. It makes sense if the engine has to deal with mud all the time. It just seems like the architecture of this bit doesn't lift the cuttings enough for the vacuum to suck them out. This is for Shaper Origin, so a regular router might not have these issues.
