I'm backing up Cherrybomb on the Proto chrome splined ratchet combination wrenches as they are my go-to tools for a big part of my job tasks (aircraft maintenance).
I manage to use them in some awful tight spots cramped with metal parts, tubes and wire bundles, and they do a VERY nice job...
These came in a couple of days ago, the finish is stunning and the ratcheting action sound made a grumpy old coworker smile. I'm really impressed of the way the splines grip a 12 point engine bolt.
I don't know if this product is available in the US but at the base maintenance facility I work at we use a lot of Motip Penetrating oil. A couple of days ago I managed to stir a couple of stuck link bearings on the V2500 eng aft mount. Hope that helps.
Some quality bits I've used recently with a pneumatic screw buster and hold up pretty good:
Apex
PB Swiss
Wekador
And some to stay away from:
Bahco
Beta
A320 Family mech here, working as well on MD 82/83. Used to turn wrenches on BAE 146/Avro RJ's and ATR 42/72's. I'm scoping Long Haulers - A330 and B777 will be my next type training courses.
Italian manufacturer GT Line (and Explorer cases) makes the portable tool cases for Stahlwille, Bahco and Facom, in Italy the product can be found at around 300 EUR, in UK 300 GBP, the rest of Europe sells it for around 500~800 EUR.
Zkling, please do mention the brand here if you remember it someday. A cheap alternative is an "US Pro" toolbox, but I highly doubt it that it's gonna make it through airline luggage handlers' excellent service.
Don, below is a link to a thread I've started on these boxes, I still need one, I'm a start-up aircraft mech, soon to be contractor. Finky is 100% percent correct - those boxes are bulky, heavy, cannot hold many tools and are really expensive, so think twice before jumping for one. Anyway...
Hey guys, I'm looking for a certain type of plastic trolley tool box - rugged, waterproof, with drawers as it is one of the most convenient methods of tool organizing and transportation I ever saw.
My choice narrows down to these:
Peli Case 0450
Stahlwille 13217
Snap-on KMC 18062...
