Looking for some suggestions/confirmation here.
The work is mainly tightening bolts from M6 to 1" and drilling a few holes in tight spaces. Repetitive work, daily use - the below list once/day for assembly and about half that for disassembly.
8) 1" bolts ~600 ft-lbf
2) 7/8" bolts ~400 ft-lbf
8) 3/4" bolts ~300 ft-lbf
12) 5/8" bolts ~200 ft-lbf
10) 1/2" bolts ~100 ft-lbf
16) 3/8" bolts - tight
3) 5/16" bolts - tight
2) M6 bolts - tight
The torques are very approximate minimums - all the fasteners use crimped lock nuts so you typically run them down until they seat then let the impact rattle for a few seconds, longer on the biggest bolts.
Drill
1) 1/2" hole + 1/8" pilot
3) 3/8" holes + 1/8" pilot
2) 5/16" holes + 1/8" pilot
Shop is currently using all Snap-On tools
1)
PT850 1/2" pneumatic impact (for 1/2" and larger)
2)
CT8810A 18v cordless impact wrenches (for 3/8" and smaller)
1)
CDR8815DB 1/2" 18v cordless drill
The biggest thing that I want to try and improve on is the inefficiency of having to use the 1/2" pneumatic impact on the majority of the bolts, dragging the air hose from one side of the vehicle to the other and back/forth. The other is the drill doesn't really fit in a couple of the spots causing the hole to have to be drilled at a slight angle.
Here's my proposal
1) Milwaukee 2767 or 2863 High Torque M18 with HO6.0 battery
1) Milwaukee 2852 Mid Torque M18 with HO6.0 battery
1) Milwaukee 2503 1/2" drill M12 with 3.0 battery
Might still need to use the pneumatic impact on the 1" bolts, but can probably use cordless for everything else and/or use both if there are multiple people working on the same vehicle without having to wait.
There is not room for the big 1" drive (the pneumatic barely fits with an 1-1/2" socket length wise.) The length of the 2767 is 1.19" longer than the PT850 but can go with a shallow socket instead of a deep to make up the length difference.
Thoughts/opinions/comments/suggestions welcome...
