[M12 Pro press vs. M18 version]

Got some answers from Milwaukee customer service - I'll post here in case anyone else is looking for the same info:

• M12 - copper up to 1.25"
• M12 - BIP/IPS/galvanized up to 3/4"
• M18 - 1,800 more PSI than the M12
• M18 - 8,000 more clamps between servicing

So, if you need to work with copper over 1.25" and or iron/galvanized pipe over 3/4", you will need to go with the M18.

Can any one give me a concise answer to the differences between the two? Use both platforms/batteries and debating on which to purchase. Primary uses would be copper and iron (gas) pipe up to 1"
