TIDEWAY V Groove Router Bit 90 Degree Double Flute Chamfer and Bevel Bit Carbide Tipped Woodworking Tool Engraving Router Bit 7/8" Dia x 1/2 Inch Shank

I needed to cut a v slot into some thick Ultra High Molecular Weight Polyethylene Sheet that needed to have some of the base hollowed out. So I tried this router bit on some softwood first. It cut okay but seemed to heat up and discolor a little too fast compared to my many other bits. It did a good job on the polyurethane piece, however, and the angle it created was 45 degrees as needed. So I can recommend this bit for occasional special usage.

This bit cuts a very clean V groove. Due to the fact that there is no real chip clearance with this kind of cut a second pass was done to clean up the initial cut followed by sanding the V groove to remove the final fuzz that remained. Also like the fact that it is a 1/2" shank. I prefer the bigger bits for stability, grip in the collet and overall performance.

Finally a nice simple method of creating perfect fitting 45 degree cuts

used to cut 3/4 inch wood to get that perfect 90 degree fit. And the price is right. Still has good sharp edge, running at 16000 on my cnc, only slowed done to 80% of full rate. Will buy again and keep an eye on other cutters of the same brand.

Where the tip meets there is a pretty large gap that's filled with braze. Also it's been ground to a 1/32 diameter on tip, so definitely not something great if you are trying for crisp lines. The gap that's filled with braze with either dull within a foot of cutting, or break out.But, it's a cheap bit, and I'm sure it'll work great as a side chamfering bit.
