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.

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!

It works verry well for a cheap bit, my only real complaint is dulls out quickly and leaves burn marks verry easily little to easy. But in camparison to the high end bits and their price its verry cost effective and works for couple projects

So far so good using this bit for flattening surfaces of my slabs. Seems to keep an edge and makes clean passes. Be sure to not take too big a bite since this bit has a smaller diameter shaft and would tend to bind during use.

Just received this bit, used it on a few pieces of walnut and maple. it left a very nice surface finish! The tolerances are spot on and its a great bargain for the price. The extra width allows it to remove more material quicker for the larger areas and pockets. Its nice that it has a 1/4 shaft so I don't need to switch collets between router bits. Works well, easy to use!

They are so many spoil-board cutters out here where majority claim to have the best with their features. Give real CNC operators it's only a cutter, you're not making license plates. Buy cheapest to do the job, if breaks not much loss, but break a $70. bit that's going sting.
