Pneumatic Die Grinder

[The Critic]

Need a pneumatic die grinder for cleaning hub flanges, rust, etc.

I am familiar with the AFF brand but was not aware they made pneumatic tools:

I never heard of the air tools, they may be great or not. I have the 205QL from Astro, it has been a good tool, no complaints with it. Not as powerful on paper but it doesn't dog out and cleans some pretty rusty stuff with little effort.

Never heard of that brand. I use a Husky I got from Home Depo and it has been very good. It replaced the H F ones that kept stripping gears in the head

I’ve heard of the brand as we had a press from them at school. Never knew they had air tools. I have a cheap Campbell Hausfeld die grinder from Walmart that does pretty good for what you listed needing it for. That’s all I really use it for.

Why not the Milwaukee M12?

Why not the Milwaukee M12?

Just wanted a cheaper secondary option. I already have a M12 die grinder.

Have you looked at Astro Pneumatic, While not Chicago Pneumatic quality...There pretty good if you keep them oiled & greased.

Grandfather had a AFF mig welder that never really worked right. I personally would pass. My preferences for air tools are Chicago Pnuematic, IR, Florida Pneumatic or my top choice of St. Louis Pneumatic


St louis Pneumatic makes those in the USA at an affordable price.

Another vote for the Astro Pneumatic 205QL a very good tool for the money, and their CS is second to none.

I have an IR that has been with me for over 10 years. Keep it oiled and it keeps going. It came from an Army tool room so who knows how old it actually is.

I have an IR that's been great.

HF ,, top of the heap quality wise.

I’m impressed with AirCat tools and would look at their offerings.

 

[JHZR2]

I guess it’s as good to ask here as anywhere, what would guide a decision between a 20k rpm and a slower variant (3500-4500RPM?)

 

[The Critic]

Was at HF this morning and saw a "Chief" branded die grinder. It is new to their line-up and had a speed adjustment knob that does not seem to be common either. $49 and Made in Taiwan. I bought the only one they had. Build quality seems decent, noise level is reasonable and air consumption was less than I expected. We'll see how long it lasts.

I think if you did a lot of wire brushing, the slower would be better. I turn the air down on mine as the wire brush wheels are rated about 4500.

Rolocs and most stones can go 20k rpm.

It's really important to wear eye protection with these!

 

[spasm3]

I use mine mostly for brake jobs, cleaning the hub and rotor, wheel faces.

Nice. Haven’t seen these yet.

Some attachments are not rated for 20K+ rpm, pinstripe removal wheels would burn a hole right through the paint if it didn't disintegrate first, wire wheels could throw wire bristles all over the place and they can really do you harm.

So do automotive shop users generally get the lower rpm units then? Or turn the pressure down? or is there any other way to limit speed on these?

I don’t own one, but am interested in buying one.
