I resurfaced my CNC Router Spoil Board with cutter. I ran at 120 fpm with a .010" depth cut. It came out smooth as a silk.

Perfect for my task and I can truly attest to the durability now. I had to reduce the thickness of some pine planks to fit for a project. Instead of spending a lot on an electric pass-through planer, I tried this surfacing router bit. I set the depth on my router to 3/16" and went over my boards twice to reduce their thickness by 3/8" inches. These were 8x 5 foot planks and each one needed about 10 passes to complete. My router is cordless and I had a battery cycle running laps through 4 batteries but I got through the task and this sturdy little bit held up and was still making clean cuts. I literally put about 40 sq ft of wear and tear on this bit over the 3 days it took to finish.

Use this to level my spoilboard on a Longmill Mk2, works great. With the head trammed, no visible marks on my MDF spoilboard. Only caveat is there were "fuzzies" left behind on the outer perimeter with a .5mm depth of cut @ 1500mm/min. I am very new to this so it could be used error but could also be sharpness if the bit. Could've spent more on potentially a better bit but for the money, I am happy with this. Also levelled a slab of walnut with this bit and had no fuzz but had step over beyond the perimeter of the cut. All in all I would say I would purchase this bit again. 1.5 month update: Have been using this bit more to flatten reclaimed hardwoods and pine slabs. It's been working excellent so long as I make sure to cut outside the slab on the final pass. I messed up big-time in a hurry and collided with one of my aluminum hold-downs. Took 1/8" off the top before I hit the e-stop and shut it down. Have surfaced a few pieces since and it's still milling strong. No marks/ lines after a cut. Maybe I got lucky but I will grab another one of these when this one is done being abused by this novice.

Size: 1-1/2" Cut Dia-4 Wing
I surfaced a 24" by 30" slab of oak with this bit and a forty year old Craftsman router. It did the job with no problem with fantastic results. Yes the bit is bit short because it's a 1/4" shank but I knew that going in and when I made my surfacing jig table I compensated for that. Within a couple of minutes of my learning curve I was amazed by the results. I bought two bits just in case but the first one is still sharp. I only took off maybe an eight of an inch every time and let the router do the work without forcing it too hard. Very happy with the performance. Very happy with the purchase!

I bought it to use in my router sled for milling a piece of rough-sawn oak and a cutting board I built with multiple hardwoods. It got the job done, but it dulled quickly, burned the wood, and began smoking after less than an hour of use. I just bought this bit and already I've had to go online and order a more reliable brand. I should have just done that the first time.
