I work on dmaxes everyday and my 4 top tools are....
1. IR 3/8" titanium air gun
2. Makita 14.4v Lithium 3/8 impact
3. IR 1/2" Titanium air gun
4. Makita 14.4v Lithium Drill
I have never had a better 3/8" battery impact that worked as well as this makita. I brought it over when helping pat with the dash. I believe he even commented on it
.
I don't like big things in my hands so the smaller the tool the better.
Air ratchets - i have not tried. they are still fairly new and are limited in designs. I don't feel they can match up with my snap-on ratchet so i haven't even tried.
The guys at american choppers use the cordless ratchets though. :baby::baby::baby:
