Pattern Name: Surfacing Bit

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!!

This bit works great.had a piece of walnut that had been sitting out in the weather for a while. Had to make 3 or 4 passes to get it flattened. The bit did a great job. Would recommend this bit very highly.

The large 3' cutter makes routing a large slab a lot quicker, it is best to keep the depth of cuts thinner because you are cutting a lot more area at each pass. Like most large cutters it dulls quicker than smaller cutters and has to be cleaned more than small cutters. Great way to speed up processing and does the job well. Minimal sanding to remove cut lines when co0mplete.

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.

Pattern Name: Surfacing Bit
Size: 1/4" Shank-1" Cut Dia. (2 Inserts)
I will be honest, this was my first wood cutting bits with inserts. I thought it would be more economical as the Chinese surfacing bits with brazed carbide cutting tips didn't last long when cutting hard woods but now I am not so sure. I thought I'd take light cuts (.25 mm) to get the feel of the new bit but the tool chattered and gouged the workpiece. I thought maybe I needed to take deeper cuts so I tried taking a 1 mm cut on a piece of dark cherry. Not but a few minutes into the cut on my 3018 CNC router the tool chattered so bad it knocked my dust boot off, shattering it and sending pieces sailing across the room. Since losing my dust boot I have not used my router or this bit so I can't say much other than I wished I'd purchased a half dozen 1 inch surfacing bits from China instead of this bit with interchangeable inserts. Bad thing was I bought a box of inserts when I bought the bit. If I happen to find out I was not using his bit correctly in will update this review. As a retired machinist I am very familiar with metal cutters with replaceable inserts and thought I wouldn't have any problems. I ran the tool at high rpm and a low feed rate, maybe someone can tell me if I am doing something wrong? After upgrading to an 800w spindle motor the but no longer chatters and leaves a good surface finish so I raised my review from 3 to 5 stars.

this thing is not a toy a joke or anything else. it will hog though material at the rate of ten thousand samurai's across a rice field leaving no blade of wood fiber in its path. and its reusable wow just the 3in resurfacing bit I needed for all my flattening of table's and cabinet doors galore. I can't wait to use it, it makes such a mess so fast that you will be in saw dust heaven in no time. if wood chips are your fancy this is the product for you unless those wood chips are for fleas, it plows through walnut, ash, elm, oak, wood of all types shapes and colors, like butter and doesn't break a sweat. I won't say my feed's and speed's, i would wont anyone to assume that you could do it with any router and I'm doing it by hand so yeah slow and easy wins the not hospital visit cause it hogged a hole in your arm.

Size: 1/2" Shank-2" Cut Dia. (3 Inserts)
I bought this thinking it would be good for facing tenons. Unfortunately. the cutters don't align at a right angle to get a usable joint. They leave a small ridge that keeps the joint from fully closing. I tried to reset the cutters, but to no avail. The surface it left was gorgeous. So this bit is good for its intended use, but not for joinery.
