I purchased this drill, Milwaukee 299-20, July 8, 2021, serial number when the drill was first used (either that or the entire spindle was misaligned). In any case, the drill was scrap and I had to throw it away. It's possible that the drill bit I received was fake, but if it's a genuine Milwaukee drill bit, this drop in quality from a major manufacturer is extremely disappointing, not to mention they ripped me off for $150 . Of course, a drill needs to be tested to make sure it works properly…
