CENYB CNC Spoilboard Surfacing Router Bits,4 Teeth 1/4 inch Shank 2 inch Cutting Dia with Router Collet for Woodworking Tools

One of the four blades was sharpened slightly off-skew. The perpendicular edge was straight, just not the face edge. Itll still work for me, but its a hit against quality control.

This is a decently sharp bit that planes surfaces reasonably well. I have no complaints!

Good router set. I have a router but these need something more stable like a router table or something like that.

Please stay away from this bit. Spend a little more for Freud which is a top tier brand. Notice many of these reviews are people who received it for free. This could have ended a lot worse than just a damaged router (not to mention my wood piece). I will say, though, that I was refunded but still - a product like this shouldn’t be on the market

It flung off and nearly killed me

Muy buena calidad

I wanted this to be a good product, but am slightly disappointed. I ran a few test blocks through to make a tongue and groove board. The end product wasnt bad, but it was a little looser than I would like to see for a tongue and groove joint for say...cabinet doors. The router bits that I received made a groove that was 200ths of an inch bigger than the tongue. Slightly perplexed by the extra slop, I checked the bits cutter heads with a digital caliper and found that each head was a different size making the groove wider than the tongue ( which I think was the problem). The tongue cutter heads were also each different sizes which was interesting... Im sure it would work great for some things, just not cabinetry. I would probably invest in a higher end router bit set to avoid the inconsistency. Pictures will show the numbers that I was looking at on the bits.

These work but not what I expected.

Im flattening a very large white oak slab and this thing is making it so much easier. I have it on my router sled that I built and its leaving a very clean surface.

Do not try this buy a 1/2 inch shank bit this one bent and is dangerous .
