I had a project that required lots of branch conduit and lots of 1-5/8 and 7/8 strut. I don't mind using a hacksaw for smaller projects but when making a lot of cuts all the time I want something to speed up the process. Well, I have always been a big fan of metal cutting circular saws, but they make a mess and cost a lot. Since I was looking to cut strut, rod and small conduit neatly and quickly I started looking at the M18 bandsaw... already had the M12 batteries and driver so I decided to give the little tiny 12v a try for 1/2 the price (or so). This thing is the best tool I bought all year, possibly the best value for the money I have ever gotten from a cordless tool. The first day I had it I made cuts all day for 3/4 EMT, deep strut and 3/8" rod. Battery lasted the whole day and into the next! And I was using the standard M12s, not the 4 AH fuel ones. I love this thing and highly recommend it. Its so small and light it looks like a joke. I assure you it's not!
