This is a tool that has been in the Milwaukee M12 arsenal for a long time. I believe they have had this tool out since late 2008 or early 2009. Personally I think this is a must have tool. Not only will this help with getting in tight spaces, but it will also help with production. The Milwaukee M12 Copper Tubing Cutter will make your life easier, plain and simple.
This cutter uses a blade copper cutting wheel to make fast accurate cuts. The cutter has a 500 rpm motor which means you can cut pipe much faster than the traditional way. Even the head is well thought out. Place a pipe in the front and it will automatically adjust to any size pipe from 3/8″ to 1″ which pretty much covers all the major sizes. As you know copper pipes are filled with water and water can wreck metal parts. Milwaukee designed this with a stainless steel and sealed front end to prevent this tool from getting damaged from water.
The tool weighs about 3.2 lbs, so it's not heavy even when working overhead. As I said earlier, you can really get into tight spaces with this tool. While the length is 14″, you only need about 2″ of clearance for the front of the cutters to get into. As with the other Milwaukee tools, this has a built in battery fuel status gauge.
One item I would really like to see improved with this tool is the battery. Milwaukee has 2 Ah batteries available on the market. This kit comes with their old 1.5 Ah battery. You will still get 200 cuts per charge, but having the 2 Ah battery will easily increase the production of this tool.
Overall I have to say I still love this tool. I have talked with numerous plumbers who live by this tool. I always hear the same thing that this tool just makes their life much easier and who can argue with a pro?
