Review on Kodiak Cutting Tools KCT136442 Diameter by Bryan Covington

This is the first cutter I've bought. God, this thing exploded like there was no tomorrow. I've used it with both my rotary tool and my corded drill to carve two AR-15 receivers 80% deeper and there was no sign of wear on the chimneys. The jigs for the lower receivers came with chisels for drilling and milling and of course aren't that good. Performance quickly degraded and/or broke. I definitely recommend this company for two reasons: 1) As mentioned above. 2) Made in America. And if for any reason I can't get from this company I would stop looking for another US & Made company or NATO country (ever booming militarized China with its toxic crap production and enormously dominated flood of safety reminders NEVER include).
