CNC Spoilboard Surfacing Router bit, 1/4 Shank, 1-1/4 Cut Dia, 1/4 Cut Length, 3 Wings, Professional Woodworking Tools by KOWOOD PRO

Good quality and smooth operation

Started off good and gave reasonably flat cuts for the price. However, by the second project it was burning the wood. All router bits get dull, but this was a little fast in the dulling department. Havent tried to sharpen it yet, but even at the cheap price, I wont buy it again.

I waited a few months to review. I used this bit for 4 slab flattrning projects so far and its still doing a great job. Would recommnd

Good lifespan on softwoods and the spoil boards. Holds its own on hardwood but definitely only has a few large cuts in it if you want full finish. I keep two. One for roughing and one just for super shallow pass finish. Been on the same two for a while.

Works as expected. Must be trammed well. Perfect for my project.

I had this for a handful of months. I used this to surface probably 3-5 of slabs and it worked great in the beginning. However on my last two slabs all I got was smoke and burning. I noticed the bit was now dull. I think of you use this for more than 1 or 2 slabs, carbide is probably the way to go.

Was sharp, straight, would buy another

Im using this to level out a log end. It does the job quickly as long as I take off a little at a time. I am happy with the results.

The first 5 or 6 pocket carves I did on the CNC using this bit worked like a champ. However, Im noticing burn marks in my wood. Im using maple and my router speed stays on 3 which is 18k rpm. Again great bit for the price, just keep a couple extra on deck.

Router bit seems a good value and seems to work well for resurfacing spoil board (HDPE plastic in my case) which is why I gave it four stars....except if you get a bad one. If purchasing I would check the carbide tips by place against a smooth surface like a 1-2-3 block or piece of glass (with a think piece of paper to eliminate the glare). Then look with some back light for the contact point of the carbide tips. Amazon did a good job at quickly replacing the one in question quickly.
