Pros: 1/2" shanks Multiple size options Bearings work without problems Cons: I didn't expect tool quality from Freud or Whiteside, but I got it expected it to work better. These tips were more of a proof of concept calibration. I ended up making six passes, each about 5" long, in various hardwoods, and at the end of the last pass it spat out burnt chips. The cutting edge is worn much more than expected and doesn't seem to last long I think it would be fine with softer wood and/or multiple passes but if it can't push a 3/8" shaft through multiple 5" cuts, it doesn't fit.
