Slab Flattening Router Bits 1/2 Shank, 2-3/8" Cut Diameter, 12*12*1.5mm Carbide Insert, for CNC Spoilboard Surfacing/Planing/Flycutter/ Slab Leveler/Rabbeting

This thing is a beast. Well made and works very well as long as you don't get too aggressive. I love the multi-sided cutter heads. I've used it for about 4 hours so far and it still cuts as smoothly as it did out of the box. Definitely a good value for the money

Very sharp and works great.

Very smooth running, the shank is long enough to allow for a variety of uses. The surface quality is excellent . When the time comes I will definitely buy another one of these, they are an excellent value.

This is an extremely well made bit for the price. It handled my project incredibly well. Took 1/4 inch off a table slab. Was very impressed with it

New to slab flattening. I made the mistake of purchasing a cheap 15 bit at first. I wasnt pleased with it at all. But this bit is awesome. It flattened walnut like butter. I ran 4x slabs thru it back to back. Towards the end I think it got a little hot but it performed well. Its worth the money to buy this bit. Very happy.

I’m using this bit to flatten oak wood cookies and it works great in my 2 1/2 hp fixed base router. I’ve flattened about 100 cookies so far (4’ to 12 inch diameters) on both sides and the bit is as sharp as when I flattened the first cookie. I have not replaced or rotated any of the carbide inserts yet. The surface is not perfectly smooth but the router marks are easily removed with a random orbit sander.

Update.... this bit will not seat all the way to the line in a Triton T001 router! The triton collet is only 1 1/4" deep and the bit requires 1 1/2"! I have been buying the Binstak 3 blade from Amazon for $17, it's fine but thought I'd try this upgrade. I just flattened a 7' epoxy river table , here is my experience. I have a Bosch 1617 2 1/4 hp router and I will say it's not quite enough power for this bit imo. It's fine as long as you don't take off more than 1/64 or 1/32 max. It handles the wood at that depth fine, but started to bog down on the epoxy at the 1/32 depth. I will say that it cuts very smooth, no vibration and leaves a lot less marks than the cheaper Binstak one. I flattened both sides and it still had sharp enough blades that I think I can keep using it on the next slab. Summary, I like it better for sure, but may need to upgrade to a 3 hp router if I want to get more aggressive and take off 1/32 to 1/8 at a time. Or I may use the Binstak for initial aggressive passes and then switch to this one for finishing passes.

The picture shows the aftermath of creating a 1/2" slot against a 2x4 framing to secure the 1/2" PVC bead & board panels for the front steps I'm building currently. Because this panel design was an afterthought, some of the 2x4 pieces were too secured to use the table saw to create the channel. With that said, I took out some wood screws where I had to make the channel and by accident, I missed a few and instead of the cutter head getting demolished, it ate through the screws heads that weren't taken out. So there were some chipping that occurred on the blades, but this is after zipping through 4-5 epoxy coated screws. I was very pleased with the results. I also love this design like the spiral head cutter on a planer as I can rotate it. And the cutters are replaceable so it's well worth the money. I'm using this also on Bosch router. Important: I'm not sure how people are destroying the cutterheads fast but I made 3-4 passes to reach the 1/2" depth. You never want to cut anything deeper than 1/8" at a time as it can grab the piece hard or make it go in different directions. Speed was at the maximum (7 on my Bosch). Considering this was relatively wet pressure treated wood, I'm very satisfied with the results! Very durable router bit 👍

That thing looks mean for a reason....it is. Put it on my router and did test passes on some Amarone and walnut. For a 1/4" pass it didn't so much flinch going through it. the cut is super clean and precise. would take 75% cut width with almost no feedback from the router. It just eats the wood likes its his last meal. the bit is well balanced and didn't vibrate, or at least I could't detect any bad vibrations. Get yourself 12$ worth of spare inserts for good measure and just flatten away. That thing is a steal with similar items going for 50$ more.
