CNC Spoilboard Surfacing Router Bit, 1/4 inch Shank Carbide Tipped Surface Planing Bottom Cleaning Cutter Slab Flattening Router Bit, Wood Milling Cutter Planer Woodworking Tool

Used this bit to level a 50x50" wasteboard with 16ga. air nails holding it in place. Chewed through the wood and air nails like they weren't there. Easily worth the pocket change to get the wasteboard flat.

The bit arrived very fast. This is a high quality bit. I have resurfaced multiple spoilboards and the bit has done a great job and no signs of dulling.

The shank isnt long enough for a router sled. I have a 3/4" thick sled, this will protrude maybe 3/8 of an inch below. This is definitely a cnc bit. My mistake.

wish it had a 1/4 inch shank not a 1/8 inch that needs a 1/8 tp 1/4 collar

I loved the bit performance when I first started using it, but after 3 uses on mesquite, the blades are too dull to use, creating horrible burning on the wood surface. If the blades were a bit harder and resilient, this would have been the perfect for me. Now, I have to find someone to sharpen the bit.

I ordered this to remove the surface of a deeply scratched butcherblock tabletop. The Butcherblock top was 2'x4' of hard maple. I was able to use this to mill about 1/4" of the surface in 4 passes 1/16" at a time. The last pass was as clean and smooth as the first, leaving a finished slab that didn't need any planing and only a little sanding to complete. I would defiantly recommend this to anyone flattening slabs using a router and sled.

We purchased this router bit to cut the underside of a handrail. The tool is very high quality and does an excellent job. Can highly recommend!

I made a router sled and flattened a piece of maple that I cut from a tree. I will add hairpin legs and do an epoxy in the middle part but this blade worked well on my router. I think it’s getting slightly dull after how much I had to take off the piece of wood but I view this as a good value for the money. Now I can hit it with a palm sander and make it perfectly smooth.

Surfaced both sides of a 40"*12" slab of maple without a prob, but took it easy with 1/8" thick passes and only taking about half the cutting width on each pass. Leaves slight marks between the passes but nothing that can't be sanded off.

I was levelling a big table , and as I got to the 2 stage the blade started turning blunt and now I’m half way stuck levelling a table

This little flattener was a perfect choice for flattening our waste board and cutting boards....will most definitely buying another one.

Ideal for re surfacing spoil board

Perfect just what the hubby needs
