I needed to surface my CNC’s spoil board and I’m making some end grain cherry and maple cutting boards. This tool worked great for both projects.

Works well but the inserts aren’t very well aligned. Will need to be adjusted for flatness

It worked great for the spoil board, smooth finish and it is very sharp.

I've had a number of surfacing bits for my CNC and this one is by far the best. Super smooth cuts. Did a great job on some really hard wood. Better than my planer (no snipe). And the bonus of having 4 sharp edges that you can rotate around when one gets dull. Price was great, too.

The Genmitsu Surfacing router bit with carbide inserts is fantastic! I am an avid woodworker both professionally and by hobby. I have found on occasion the need for a wide router bit for various reasons. I find the straight flute cleanout router bits are ok but are more for cleaning up edges and flush routing and not for surfacing (maybe making a dado or rabbit joint tho). This router bit is perfect. My Bosch 2.25hp router took this like a champ. I swapped the collets out and this slid right in. I have in the past found off brand router shanks too loose or too tight for my router collet, but this is an accurate 1/2in shank (0.4997in according to my digital caliper). I set the depth to about 1/32 and did a little dance on the top of some old rough douglas fir. The surfacing bit did an amazing job. I had no catches even going over the knots. The bit seams to be rather well constructed and balanced. I experienced no awkward vibrations while using it. It did NOT come pre oiled with that sticky nasty protectant that I often see on tools coming from overseas. I plan on purchasing a router/cnc machine in the future and I will be very glad this piece is on hand! Pros: 4 inserts that can be rotated before changing them out completely. Accurate 1/2in shank Includes torx head insert removal tool. Con: No protective case. I refuse to use the large box it came packaged in (product package not shipping package), I will have to make a small protective box for it.
