Tunnel Rat

I'm a licensed plumber working in commercial construction, and for the past couple weeks I have been experimenting with a set of my personal 12V Max tools (impact, drill, pivoting recip saw, light) to see how they hold up when the norm is mostly 18v and 20v on our job sites. So far, they have held up really well and my co-workers are amazed at how well they perform considering their size. I will say that the impact driver has been getting the most workout as I have been running no-hub cast iron for quite some time and that has really put that little tool to the test. Luckily, I have combined two different kits and have four of the 1.5Ah batteries and they seem to hold a charge fairly well...but it sure would be nice if Dewalt would come out with a 3.0Ah battery. Now I understand that the 12v line of tools probably weren't meant for commercial construction but they're so light weight that it's almost effortless to wield them on a daily basis.

I see... Then thats probably the problem. I'm used to just spinning the chuck forward on to my bits, using the Rohm. With the Jacobs, I have to actually ratchet the chuck? I'll give it a try. Thanks!!

Hello, New member and first time poster here. I just recently purchased a DeWalt combo kit that included a DC988 hammerdrill, impact driver, as well as 2 18V XRP batteries and charger. Just out of curiosity, I went and looked at the chuck and it's a Jacobs 700. I happened to look at the chuck on my DeWalt drill at work, and it's a Rohm. I have had my personal drill for maybe a couple weeks at the most, so I'm curious as to how I ended up with the Jacobs chuck if DeWalt went to using Rohm in their new hammerdrills? Last weekend, I was working on a project at home and needed to drill a few 1/4" holes. So naturally, I whipped out my trusty DeWalt drill, and on the first hole... the drill bit slipped out of the chuck. Needless to say, I was a bit perplexed. My company supplied drill on the job has never done this. Then again, it has the Rohm chuck. How would I go about getting a Rohm chuck for my drill? Thanks in advance.
