Milwaukee Tool continues to wage a full out assault on all air tools. Coming later this year this M12 FUEL offers 20% more power than the leading pneumatic die grinders. With 4 speed controls set at 10,000, 15,000, 20,000 & 25,000 RPM you now have much better control over matching the right accessories with the right speed for the right application. Sounds like bare tool will launch around $160 range but they may tweak that slightly before Pre-Sales open up. Straight Die grinder, angled die grinder and extended die grinder with similar features are likely coming in 2020 as they continue to expand their cordless automotive lineup.
