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 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.

Works pretty well. Requires a lot of sending after flattening .

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.
