Review: Solid choice for flattening slabs - and a few tips - I decided to give this router bit a try for flattening some slabs of cherry. I've had absolutely no problems with this bit so far - I suspect the reviewers who experienced burning or rapid dulling of the bit are overheating it. You must have a variable speed router to run this bit at the right speed. This bit can remove a lot of wood in a hurry, but it works much better if you take it slow. Here are the details I've found that will maximize your success with this bit: 1. MAX RPM IS 16,000 - I found this answer from the seller in the questions above. Slower works great too. 2. Make passes of only half (or less) of the cutting width - in this case 1" or less total for each cut. 3. Keep your cutting depth on the shallow side - 1/8" to 3/16" works best for me. I'm using a medium sized router (1-3/4HP), and it starts to bog down and overheat when I try to cut 1/4" or deeper. With a bigger router you might be able to make a deeper cut, but I suspect the bit will also last longer if you don't push it. 4. In retrospect this seems obvious, but it took me a while to figure it out - as the cut gets deeper, you can reduce the width of your cut and the load on the router/bit will stay the same. For example - cutting 1/4" deep and 1/2" wide removes the same quantity of wood as a cut 1/8" deep and 1" wide. When a warp in your plank forces a deeper cut, you can make narrower passes instead of adjusting your depth of cut.
Review: Stays sharp surprisingly well - I am very surprised how well this cuts. I have leveled about 20 board feet of red oak so far and it's still sharp. Money well spent, I will buy again when this gets dull.
