I spent some money yesterday (cyber monday).
I've been thinking of a battery powered grinder for some time, I think it was L Ross that mentioned a black friday deal on a $79 Milwaukee.
I was himmin' and hawwin' all day...I won't get into ALL the details, as it'd be 20 paragraphs. I looked at Milwaukee's stuff, as well as other brands...and I was looking at a "off brand" (Einhell) pretty hard, great pricing on one with a Brushless motor. But, since I already have Milwaukee M18 Fuel Lith-Ion batteries and charger, that was really the only smart direction.
I just decided to buy once and cry once, going with the Milwaukee. I bought a 4.5" grinder, and "compact" 1/2" Impact wrench. During my research, I learned Milwaukee has at least 4 different models of the 4.5" grinder...and I just couldn't get on board going with the lesser models (brush motor), and opted for the Near $200 brushless unit (2780-20).
During my research, I learned Milwaukee (and other brands) have really "upped the game" on their impact wrenches, quite high torque ratings on them. I have always used air impact wrenches, but have wondered about the battery powered units. Milwaukee came out with this 1/2" "Mid-Torque" in a compact size, in the last year or so. It is rated with 650 FT-LBs, which is higher than the cheap 1/2" Air impacts I have. Since I was spending money, I decided to pull the trigger for the 2962-20 at the near $200 price.
Merry Christmas to me.
