They aren't as sophisticated as some of the other big brands. BUT - that's 33% of the cost with 90% quality. So you can count. You work very well in the CNC environment. I've ordered a few dozen over the year and have no problem running this at 100, 200, 250 IPM. It wears out a little quicker but the cut quality is great when it's sharp and again that's great quality. As the price goes up (and they are), they become less impressive. Hope this helps the next guy!
