CNC Spoilboard Surfacing Router Bit 1/2" Shank, Slab Flattening Router Bit Carbide Planer Router Bits Wood Milling Cutter Planing Tool Woodworking Tools By BINSTAK

I decided to give this router bit a try for flattening some slabs of cherry. I've had absolutely no problems with this bit so far - I suspect the reviewers who experienced burning or rapid dulling of the bit are overheating it. You must have a variable speed router to run this bit at the right speed. This bit can remove a lot of wood in a hurry, but it works much better if you take it slow. Here are the details I've found that will maximize your success with this bit: 1. MAX RPM IS 16,000 - I found this answer from the seller in the questions above. Slower works great too. 2. Make passes of only half (or less) of the cutting width - in this case 1" or less total for each cut. 3. Keep your cutting depth on the shallow side - 1/8" to 3/16" works best for me. I'm using a medium sized router (1-3/4HP), and it starts to bog down and overheat when I try to cut 1/4" or deeper. With a bigger router you might be able to make a deeper cut, but I suspect the bit will also last longer if you don't push it. 4. In retrospect this seems obvious, but it took me a while to figure it out - as the cut gets deeper, you can reduce the width of your cut and the load on the router/bit will stay the same. For example - cutting 1/4" deep and 1/2" wide removes the same quantity of wood as a cut 1/8" deep and 1" wide. When a warp in your plank forces a deeper cut, you can make narrower passes instead of adjusting your depth of cut.

I am very surprised how well this cuts. I have leveled about 20 board feet of red oak so far and it's still sharp. Money well spent, I will buy again when this gets dull.

Flattened a whole 1.5 m × 1.5 m slab of hardwood; did a decent job, but there are some tear-ups.

Excelente llegó en buen estado y en el tiempo esperado, llegó hasta Colombia!

Works great! Good value for the money. I used it to level a piece of exotic project wood (not my spoilboard) It worked as well as, or better than a planer! I was very surprised to see no machining marks at all.

I abused this bit while using on a router sled cutting endgrain maple. When I finished, it was dull but I cut both sides of that table and had enough shavings to fill a pick up truck. Good value. Hopefully you won’t abuse it and it will be just fine.

Used this for slab White Oak. Eats through wood. Take a small skim cut and take your time. Get your RPM right wiht the router. Leaves the surface smooth and ready for a planner cut.

Works well. I overloaded the cut, but it did not damage the tool. Very satisfied.

I recommend. Very nice cuts and well balanced.

Es de buena calidad y tiene buen filo me gustó mucho

Excelente bit para trabajar la madera

it does it's job, not the smoothest cut but also not a 80 $ router bit.

It came as advertised and in a timely matter. I used it to flatten a 38" maple cookie for a coffee table with a router sled.Worked excellent and held its edge.
