BINSTAKCNC Spoilboard Surfacing Router Bit, 1/4" Shank, 1-1/4" Cutting Diameter, 3-Flute Carbide Wood Surfacing Router Bit

I just used this to flatten a 4-sq-ft rough-edge slab, for a table top. It worked fine and at the end of the job was still plenty sharp. That's excellent performance for the price.

Been using it to flatten oak slabs at work & after the first few it dulled down, I use diamond paddles to hone it which works if you do it right, I also bought 2 of these so I switch up after 2 slabs as the bit gets hot & found that it works great when it’s cooled down so it works better & cuts quicker rather than burning the wood & struggling from being too hot… only takes a few minutes to hone these as well so no biggy… would buy again on a cheaper note & 2 or even 3 of these to switch up is a great way to keep them less stressed out & last longer if you’re doing a lot of flattening hard wood

I use this with cnc router and it has been an amazing bit. Easily surfaces boards for a perfectly flat surface to engrave.

I used this to router plane a small walnut side table with some epoxy. I probably won't be able to get anymore use out of it. It has burnt the wood a few times.

Ordered to surface and plane slab maple wood. Bit cut very good. Still very sharp after surfacing two slabs.
