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

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 .

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

Using this bit to grind out material from a butcher block. Figured after how much material I was digging out that the blade would soon dull. Didn’t happen. Still running strong.

Muy buena calidad

I ordered this for using with my CNC. Works great for waste boards. Better than my way more expensive bit for the same job. I recommend it.

Could be me, but this bit grabbed my project and threw the bit out at me. I don’t know if the bit is too wide for the equipment it’s made for or if my cut depth was too much, but please use caution

I received this item for review, I was not paid to review it. The product shipped quickly and was well packaged. It even had a spacing washer included. That will be help later when the blades have worn a little. On the first pass the blades did pretty well. There was a little burning on one of the layers but I was cutting cheap plywood to get a feel for the set. The fit of the joint very clean, tight, and fit perfectly. The blades are very sharp and held up well for the 16 cuts I did. The bits are solid and should hold up well as long as they have a chance to cool a little between cuts. There is enough metal to keep the heat down but they are cutting a fair amount of material. That is the nature of this type of bit. The spacing washing may come into play as the blades wear a little. It is nice to have it in the package. These blades did a great job of making a clean. Just make sure the nut on top stays tight. After heating and cooling form use I had to snug it up a little.

Absolutely awesome product. This pair of router bits very cleanly cuts tongue and groove joins that fit well but not too tight. The joint itself isnt a friction fit and allows the boards to slide freely so its best used foe glue joints. After the initial re-tightening of the keeper screws on the bits, everyrhing works as advertised. I dont have many joints cut with these so I wont comment on the longevity of the blades, but my initial impression is very good.

I built my own flitting sledge. And flattened 2 2×12 boards. Always wanted to do that.
