1 1/2" Surfacing Bit w/ Replaceable Cutters 1/2" Shank

The bit works great, but for the additional cost for replaceable blades a solid bit would have worked for my applications. I won't be using it enough to have the bit dull and need resharpening enough times for blades to be replaced. Bit it works very well!

It made our project go way faster. It did such a nice job.. way less sanding than other bits we have used. Stayed sharper you.

This is by far the best bit I have found for flattening wood slabs. It has replaceable cutter heads and comes with extras so its pretty cheap to keep running long term.
I use it in a router sled. I'm thinking it can be used on a CNC machine too.
