Using triangle carbide inserts in a homemade cutter was a bad idea. || RotarySMP

Don't do this. Triangle inserts like these TCMT 110202 have two issues: 1/ being 60°, they always engage, or at least rub on the bottom 2/ there is only one edge to locate the insert in it's pocket, and that is not rigid enough. The inserts come loose after a couple of cuts, as you can see in the video I made when using it. https://youtu.be/dhZjZkwXvLw ____________________ If you enjoy my content and would like to support my channel...
