Size: 1/4" Shank-1-1/4" Cut Dia. (2 Inserts)
The media could not be loaded. Flattened my first end grain cutting board with this. Can't speak to the longevity but I had no issues with both sides of this board. Cut was pretty fast and the finish was good quality. Came packaged with this wax coating that was shed on the first cut.

Size: 1/4" Shank-1-1/2" Cut Dia. (2 Inserts)
I purchased this 1 1/2 inch spoil board surfacing bit out of curiosity, knowing 1/4 shaft may be a little small to sling that big of bit. I run a trim router on my CNC and so not high performance to start. The bit I got cut nicely in knotty alder but had a lot of vibration and was extremely loud. I reached out to the company asking a few questions and they replied back almost instantly. We exchanged question and answers and prior to me asking or them telling me I got notification they had refunded my money. I wondered if there was a factory issue and would gladly taken a replacement. I ended up taking the refund and purchasing a second identical bit to give it another try. I now know my trim router was most of the issue and contacted them again to let them know what I found and their first bit was fine, offering to pay for it because of the refund. They denied payment, thanked me for the update and hoped I continue to buy from them. Customer service like that now days is unheard of in my experience and this company has secured my business as long as I can use the consumables they offer. Thank you for being good to your customers.

I had a customer that wanted a 11’-6” live edge oak office table, I was able to find a 20’ X 8’ slab of 127 year old oak, dried in a warehouse for 5 years so it was rough and very uneven. I am making the entire desk out of this one piece and have been milling it myself, I have used this bit the entire project so far and it is still cutting perfectly flat and not one burn yet and I still have yet to rotate the knives. This bit is absolutely worth the money!!

just used this in my router sled and the extra cutters, old one has 4, really make a difference. So much smoother on the cuts with the direction your traveling not really mattering to much beside weather the router wants to run or not. Spins nicely with little vibration and is really worth the money spent on it.

Oh how sweet this tool is to use. Cuts a wide area reliably and smoothly. Minimizes cleanup. I’ve been working on a live edge slab table top. I tried using planes and sander’s to get a flat surface and wound up with the surface equivalent to the ocean. This tool has completely changed my approach. Thanks technology for your contribution to bolster my skills! BTW, thanks to Amazon for providing this seller the opportunity to introduce me to their products.

I ordered 2 because you should have a back up, right? Both of the shafts bent under light cutting - taking like 1/8 off. One of them went flying, luckily toward a wall and not me. Dangerous.
