When you need high feed, don't go deeper than half the width! If you need a deep cut, get ready to work very slowly! I don't mean it's a bad thing, but it doesn't tolerate bugs and breaks very easily. Watch your feed and depth and the cutter will work great. Excellent chip evacuation and seems to be holding its edge well. Very few thin end mills have that much cutting length, so this is one of those must-have tools in your toolbox, but it also demands a lot of respect.
