Which screwdriver? When you say old dewalt 7.2 I picture my old dewalt like this that I really liked,
https://www.amazon.com/dp/B000051WQV/?tag=atomicindus08-20. The battery did and I don't have anymore dewalt tools so never replaced it. Was just looking for a milwaukee version not too long ago and didn't find anything. My m12 fuel hex impact does a decent job of replacing it since it's pretty small but still liked my dewalt flex screwdriver and would pick up a Milwaukee version if they make one. Used my dewalt for many years since it was one of the only options besides a bigger impact drill. They did have the cheapo black and decker type screwdrivers but they were junk. The dewalt was a nice little tool when needed. I used it for interior work on cars and also around the house.
Just found it,
https://www.homedepot.com/p/Milwauk...gclsrc=aw.ds&dclid=COPv5M22o9kCFUGvTwodn5cN-w. Is this something brand new because I have searched a few times for one and never saw it. Don't remember seeing it on the milwaukee posters listing all the m12 tools you get with new tools either.
The dewalt says 80 inch pounds of torque and the milwaukee says 44. That seems really low or the dewalt seems really high? My dewalt wasn't ever crazy powerful so not sure how the milwaukee at half the torque would do?
I think my m12 is the brushed version.. I just bought it off eBay or Amazon not long ago cause I was bored one night, and yes that's the same 7.2 Dewalt I have, which was great for its day.. the m12 is a little more powerful being slightly higher voltage. That m4 is less powerful than the dewalt I'd think..
Not sure why, but I just bought a cheap aftermarket Dewalt 7.2 battery for like $15 or something off eBay for the screwdriver last week. I'll probably never even use the thing again after using the m12 and it being a little stronger..
I've read that Dewalt screwdriver was hailed by electricians at one time.. honestly, a small extension on the m12 would probably give you more ability than the Dewalt, but the hinged Dewalt was a real nice feature.. I've thought about buying the m4 in the past, but I just couldn't bring myself to spend the money on a single tool battery platform when the m12 bare tool is so cheap online.
I'm sure the m4 is decent, but Dewalt has that dumb gyroscopic model now, and makita and hitachi both make similar screwdrivers to the old 7.2 Dewalt that "by themselves" are probably better than the m4. Doesn't make sense to me to buy it - if you are gonna need a separate charger, a different battery, the makita is probably a better choice over the m4 if you're set on that style of driver.
And actually, lol, I just looked.. the 7.2v makita articulating screwdriver is discontinued (but still available).. Makita has instead, redesigned and updated it into a 7.2v articulating IMPACT driver, but it keeps that articulating screwdriver body.. would be a nice feature if you could lock out the impact if desired. Gotta say - nice looking tool..
So yea, if you're in love with that old dewalt 7.2, and want a similar, updated, better, dual speed, led light, soft grip, 220 inch pound, Lithium version - brand loyalty aside - this is probably the best choice, in a 1 pound package. Pretty hard to deny that much... you need a different battery, and different charger for the M4 anyway - so **** it, get a better tool (sorry Milwaukee)

Makita has a pretty decent 12v line going.. better than Dewalt's at least.
