Great tool. Nice and compact. Fits into tight spaces well. Could use a little more power but that wouldn't stop me from purchasing it again. CPO has been great to deal with.

If you're looking for a high-RPM tool move on. With other M12 tools turning at up to 3,000 RPM, you'll immediately notice what "max 250 RPM unloaded" means. It gets in tight places, is very controllable and makes you want to skip using manual ratchets from now on. Keep it, and the 1/4" adapter ready for ANY/ALL home projects.

when I take a bolt off and I need to turn it harder than 35 foot lbs how hard can I turn it , using like a breaker bar in foot lbs before breaking M12 ratchet
Thomas Balch on Sep 8, 2015
BEST ANSWER: The Milwaukee 2457-20 is rated to 35 ft/lbs of torque
After you hit the maximum torque when tightening a bolt or nut can you then use the tool manually to tighten it further?
Can you use the tool manually to break bolts free?
T&D Electric on Apr 14, 2016
BEST ANSWER: Yes, you can. I use this ratchet on a daily basis. And I tighten the bolts like any other ratchet. Still going strong. I love Milwaukee.

New Vs. Reconditioned

What's the difference between New and Factory-Reconditioned?

Factory-Reconditioned products have been returned to the manufacturer and are restored to like-new operating condition; they go through a rigorous testing and inspection process. Plus, they offer a significant savings vs. new.
  • Reconditioned products may have minor cosmetic blemishes or scratches that do not affect item performance.
  • Reconditioned products may not come with all of the consumables the new version comes with (bits, sanding pads/papers, cases, etc.).
  • Both come with a manufacturer warranty and are covered by our Money Back Guarantee; New is 30 days, Reconditioned is 120 days.
