Recommend me a compressed air drill

[Ross365]

I've never owned such a tool, but think it might be useful to do re-rusting under the cars - fast and compact?

Any comments on this rationale, and/or what to buy? My compressor is only 8 cu ft/min, with a 75 litre tank
Thanks

The fast ones are a tad gutless, the slow hi torque ones are going to be too slow and both are quite greedy on the air.

I only find a tool like that useful for wire end brushes to get into tight corners especially where 3 panels meet, then I would choose an electric drill. Everything else an angle grinder, electric die grinder or slower speed sander/polisher for less violent action and fewer flying wires.

i have a cp half inch chuck slow speed drill powerfull as hell. can easily snap a half inch drill bit .then a high speed desouter drill real nice both dont realy use much air the fast ones ideal for drilling loads of rivets etc . dont buy cheapo clarke or sealy not powerfull and consume a lot of air

Maybe really expensive ones are better, but my experience with them is they're absolutely crap, cordless is far better and you don't have to listen to a compressor running.

Drills are for drilling. You want a die grinder. They are designed to take sideways loads and run a damn site faster.

Electric or battery is my go to, but for air any of the ‘names’ will do what you want.

CP, desoutter, IR

Oil it before use

Edit. Probably not on your compressor though

maybe a die grinder may be of more use ,,,

snap ,,, die grinders are air hungry ,,, mighty tools and with decent burrs in them very very handy ,,, but it takes a big compressor , I was running dynabrade and snap on at the weekend and the compressor was hardly off from its run cycle. Ive never tried a battery die grinder and my 240v ones bulky in comparison . And if theres underseal you will need a small wire brush and a good supply of both brake cleaner and patience ,,,

these are the nuts for that https://www.cactusindustrial.com/mbx/

Wurth do one.

There are air and long neck / awkward access ones available

must look into one of those ,,, it looks the biz ,,, and the wurth guy calls in ,,, try their injectorex as a penetrating / release spray ,,, mighty good stuff

From personal experience yes they are.

Apologies OP

Back to drills

Whatever you do, put a box fan under one end of the car, to blow the rust and bits away from you.
I've spent several times at the eye doctor having rust pieces drilled out, even with wearing safety glasses.

Adding an air tool under their just compounds the mayhem going on.

 

[Ross365]

Well, over many years, I've worked with the angle grinder and electric drills. Then I bought a needle scaler (not used that much so far). All of these will do certain jobs, but around the suspension, access usually becomes an issue and I wondered whether a straight air-drill might be worth adding to the collection.

I've grown very conscious of eye protection over the years; usually wear the fully enclosed "skiers" googles when we start with high-speed brushes!

I find powdered abrasive, accelerated to high velocity pneumatically works best.....

yep, I have a blasting cabinet, but I've never tried taking the gun under the car. Perhaps I should consider buying a pot?

 

[brightspark]

unless you can get the car a fair way up it would be no joke getting underneath to do it and make tons of mess an airfed helmet would be the order of the day and there verry restrictive

Yes, I was being polite wrt Erie Fred's suggestion ( I find powdered abrasive, accelerated to high velocity pneumatically works best.....) , but won't actually be trying it out!

I had an air drill. Used a LOT of air. Very noisy drill + noisy compressor + freezing cold drill. Not fun.
