This is the Milwaukee m-12 pex expansion tool. With this tool you can do hours of pex work on a single charge and have the confidence it will hold up. More suited to the professional plumber due to the cost, it can also work well for the seasoned diy expert or official neighborhood plumbing expert.

Pex is a great material and has passed many states epa standards including California’s which is very strict. It has better insulation properties than copper and is less noisy when water hammer is a concern for you. There is also substantial cost savings over copper, so ask your plumber how this can be applied to your project.

The Milwaukee M12 ProPEX Expander features an extended dual-actuating trigger for better access in hard-to-reach areas. It also comes with an auto-rotating head for quick and uniform expansions. You also get a built-in LED light—something we almost take for granted now on the newest cordless tools.

Clearly the new ProPEX Expander Heads with Rapid Seal and brushless M12 FUEL motor top the charts on what’s new here. We also can’t help but note the handy belt hook—we always like seeing those. We look forward to getting this tool into the hands of one of our Pro plumbers to see the improvements over the former M12 model. We’d expect reasonable speed improvements and certainly more run-time. In the end—this looks like a great indicator that Milwaukee remains committed to maintaining and expanding its hold on the world of cordless PEX plumbing tools.
