CNC Spoilboard Surfacing Router Bit 1/2" Shank, Slab Flattening Router Bit Carbide Planer Router Bits Wood Milling Cutter Planing Tool Woodworking Tools by BINSTAK

I flattened a large white oak slab cookie with this bit. The one I used before was $80 and worked fine but got dull quickly. I tried this one out for a fraction of the price and it actually performed better! Clean cuts and still sharp against that hard oak is pretty impressive!

Cut epoxy and wood well, with no chipout for either material.

Used this for slab White Oak. Eats through wood. Take a small skim cut and take your time. Get your RPM right wiht the router. Leaves the surface smooth and ready for a planner cut.

Used for flattening live edge oak slabs on a router sled. I bought several of these bits and also a couple of bits from another company that were 4x more expensive. I found all the bits had similar cut quality and lasted about the same amount of time (no point buying the more expensive bits). I also tried the 3 blade bit but found the cut quality wasnt as good as the 4 blade bit. Very happy with these bits

Husband really uses these a lot so we are so happy to find them on Amazon.

I have used this bit for flattening very rough hybrid poplar. The bit works great on this extremely soft material. I can't say how it functions on something like white oak. You will have to try things for yourself.I would rate this inexpensive Chinese made bit highly--it has worked great for me.

The blades aren’t perfectly flat so I get swirl marks.

I got this for surfacing slabs and end-grain cutting boards with a router sled. It spins true with no vibration and works well, but dulls very quickly with end grain maple. Fortunately the carbide cutters are quite thick, and I just touch them up with a few strokes from a small diamond hone between cutting boards... takes about 10 minutes.If you don’t plan to spend the time to sharpen it, you’ll probably be disappointed. This works fine for hobby use, but does not hold an edge long enough between sharpenings for production work on hardwood.
