You can make this flattening process buttery smooth if you are equipped with the right tools.
All edges of carbide inserts can be used. Replace the carbide inserts when needed, instead of replacing the whole bit.
2.2mm insert thickness will prevent marring，provide a long using life.
It works great. I am building a 27 X 27 X 12 chopping block out of hickory. It is leveling the segments easily. The fit is very good.
Great tool to have when you need to flatten a warped board. Fast work if you have a powerful router. Only negative I could find is the 'fan effect' . It would blow chips several feet away. You can feel the wind quite a distance from the router head. At least you can see what is going on. Recommendable! Should not have to buy a replacement because the carbide teeth are replaceable. Excellent.
Used on solid walnut to flatten a slab, didn't skip a beat!
Cuts clean, is very sharp, therefore low pressure on the spindle. Able to increase IPM and get's the job done quickly. Minimum sanding to finish. (Helps to tram the spindle!)
Seems to work well, very aggressive wood removal, runs true.
