2PCS Flush Trim Router Bit 1/2 Shank for Woodworking Trimming, Double Bearing Spiral Trimmer 3-7/8" and 4-7/8" Size, Spiral Flush Trim Router Bit 1/2 Shank for Solid Wood Panels

Sharp and aggressive. Used to route a guitar body. It cut very quickly and left a surface that required little sanding. Overall, a good value.

It worked a lot better than the two blade bit it replaced. I used it on about 100 pieces of white oak. It is fantastic as long as you’re not asking it to cut more than about 1/8”. More than that it needs multiple passes.

I was skeptical of this bit, but it works great! It is not a finish-ready cut, but for shaping aggressively, you couldn't ask for a better price. I used it for making a guitar body. Using a template, I trimmed it to about 1/4 inch away from the template and went to town. It was just under 2 inches thick of a piece, and this bit handled it like a champ.I still have more work to do on the piece, but this saved me tons of time by being able to route that much in one pass.

I tested this out on a 1.25 inch redwood panel to trace out a circle. My circle jig could only cut to a depth of about half an inch. I did a rough cut with a jigsaw, then cleaned it up with the flush bit. It came out smooth and cut easily. I am very much an amateur woodworker so take it for what it's worth, but it worked well for me.

Made the purchase with cutting length a priority. The bit leaves lines. There is no overlap between cutter surfaces and the bearings aren't the same diameter. I would not recommend.

When these bits arrived I was skeptical. They looked more like parts out of a chipper truck than precision woodworking tools. But I gave them a try, template routing an African mahogany guitar neck. They produced a very smooth finish and followed the template around the end grain without blowing out any splinters. There was a little burning on the end grain, but only on the butt end, not the headstock where the wood was thinner. I appreciate the long length and double bearings. Plenty of versatility. And the half inch shank means they won't break or vibrate. These are a good addition to my arsenal.

Nice sharp cutter and seems to be well balanced. The cutter teeth stay clean and unclogged.

I made some cutting boars that I wanted to put some feature strips in, and in the past I ran into problems with standard flush trim bits grabbing the material and causing tearout that wasn't repairable.So far with this segmented bit I achieved muchbetter results without any problems.
