Review on Uxcell 1 5Mm Shank TiN Coated Carbide by Gerald Reeves

I broke 2 bits trying slower feed speeds up to this point, best to use a 1/8" ball bit first. Results just need to figure out the magic number so I don't have to buy 6 dozen bits for 1 project ;-) I tried again, 2 more bits broke but I like where it went, maybe the bits will become dull, because they also start to grind, then they break.
