I use this in my desktop CNC machine for machining spoiler boards and also for cutting grooves on the edges of signs. So far so good, cuts at the same speed as my other identical major brand W tool. So far the carbide seems to be holding. I'm happy because he's humble compared to him. I'm excited to see how it holds up over time and will add more photos as soon as I see it. It doesn't have the best packaging, you should put it in a bit holder as it will just float in the box, but given the strength of the carbide it doesn't look like it needs any better packaging.
