Sugelary CNC Spoilboard Surfacing Router Bit, 0.6cm Shank Carbide Tipped Surface Planing Bottom Cleaning Cutter Slab Flattening Router Bit, Wood Milling Cutter Planer Woodworking Tool

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.

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.

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.

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.
