Review on HQMaster 3 175Mm Straight Milling Tungsten by Justin Butler

I used these to cut and mill some purple hearts for a new knife block I was making and needed at least a 3/4 inch height of cut. Most of the work involved cutting out shapes, but there were also 4 slots and 9 knife slots that needed to be milled out. One part was cut very early in the process, but the second part completed the rest of the project with no problems. (and no change to the CNC settings) so I'm guessing the first one had some kind of material shortage. I've bought other HQMaster bits and had similar experiences, so I'll stick with the general use ones. .
