        When you add “Free Battery Online Only” it is confusing exactly how you get this battery. Must you explicitly add a battery to cart or do they automatically include when they package your shipment?

        Answer This Question

        Choose "Tool Only." Afterward, a section should say "Free Gift with Purchase," then add the battery.

              Answer This Question

              Hello Brian, Yes, the M12 12-Volt Lithium-Ion XC High Output 5.0 Ah Battery Pack is compatible with Milwaukee's heated gear. This battery pack is part of the M12 system, which powers over 125 M12 cordless solutions, including heated jackets and vests. We do want to preface that this battery style will not be as comfortable as a compact M12 battery.

                  This Milwaukee M12 battery works as advertised. I use it with a 5?" saw and for the month I've been using it I'm pleased with the performance.

                  Don't know how I ever got by without it!
                  This is a tool that once you start using it will make you wonder how you ever did without it! I am simply amazed at how much thought went into the design of this tool. Believe it or not the Milwaukee Insider is so low profile it can get into places where my conventional rachet/socket can't. This tool can also be used manually and is solid enough to break stubborn nuts and bolts loose. Sockets up to 15mm and 9/16 are pass through which makes it great for working with longer bolts or all thread. The brushless motor delivers 60 ft-lbs of torque. But the speed is what I really love - its like having all the benefits of an assembly line tool right in the palm of your hand.

                  Works as advertised
                  i have tried many ratchet wrench so far for our trailer assembly job, at first i thought its limited torque will soon make me put it on the shelf as a backup tool, but i was wrong, using it more frequently because, first of all, it is safer, never hurt the wrist from recoiling, and light weighted, make work enjoyable. one hope is in the future version maybe add a gyroscope function as the Milwaukee precision drill driver, so that you don’t struggle when you try and switch direction when you have gloves on.

                  It works as it should.
                  I honestly do like the tool and it’s every bit of the Milwaukee quality I am use to. It has plenty of power and the reach is great. The only issue I’ve had is it doesn’t work as well in narrow spaces, by that I mean the sockets stick out and the fact that they are open ended is a plus as well. For tight mechanic work I’ve found my Milwaukee 3/8 cordless ratchet gets into tighter spaces. Having both is the way to go.

                  Solid ratchet
                  I picked up this ratchet to see how it would do with certain automotive tasks where room was an issue. While it does work well and has good power, the proprietary sockets and adapters make it tough to tackle all tasks needed with the ratchet. It does have the length to reach areas your hands can’t. One important thing to remember it is more slimline with the 2.5 HD batteries instead of the larger 5.0

                  Heavy duty tool
                  I have been purchasing Milwaukee products for a long time. They have always proven to be of great quality. The Milwaukee M12 FUEL INSIDER 12V Lithium-Ion Brushless Cordless 1/4 in. - 3/8 in. Extended Reach Box Ratchet (Tool-Only) is another great product. Very powerful ratcheting, and it was an added bonus that they included a set of ratches and although it stated tool only I also received an M12 battery and a charger. As I stated the torque on this tool is awesome. This is another item that I received over a year ago, I already left a review, but you are asking me for one again, so here it is.

                  Awesome ratchet!
                  I appreciate having this ratchet when working on the cars. It provides some great power for tough bolts. Box Ratchet is a versatile and powerful tool that excels in tight spaces, offering impressive torque and speed. I appreciate its pass-through socket design and the ability to switch between 1/4 and 3/8 drive, making it a valuable addition to my tool box. The only thing I did notice was the anvil adapters can be prone to detaching when changing sockets, which can be slightly inconvenient. Overall, the rachet is awesome!
