Re: [AFMUG] Battery operated impact wrench

[Roland Houin]

I've used my makita 1/2" impact to remove tower bolts in for 40 years.. works as well as a 1/2" air impact. a single battery removed the all of the base bolts (1 1/8" socket) from a tower,   Roland   > That’s an actual impact wrench, so it’s possible. I think what I have is the DCF886B, the specs say 125 ft-lbs. Both probably have their place. The impact driver uses smaller impacts at a higher rate. I will tell you the 20V lithium ion batteries are awesome. Basically you buy whatever tools you already have batteries for. Unless they are Ni-Cd in which case I’d switch to Li ion. By sector bolts are you talking about ~13mm size, or are these more like 3/4 or 7/8” on pipe-pipe clamps? If they are big suckers, you might want to bring a cordless sawzall as well.

I just looked at a 20v DeWalt (DCF889M2) that said "400 ft lbs maximum torque" in the specs. ...but maybe it's a matter of how creative they are at measuring torque. Are you looking for an actual impact wrench like an auto mechanic would use? Or an impact driver? We use a DeWalt 20V impact driver for driving lags at installs, it’s a very useful tool. But if you are doing the equivalent of lug nuts or rusted exhaust clamps, you would need something huskier.

We are retrofitting a lot of towers and some of the sector bolts are pretty stuck. Yes, we can cut them off, but we are hoping that there is amore “elogent solution” to QUICKLY get the bolts off. Even if with an impact wrench, they break, then it still solves the problem. What do you think guys? Paul Paul McCall, Pres.
