my mac is cast made in usa with global parts
Any idea who makes it?
Just a thought... They are quite nice.MAC maybeJust a thought... They are quite nice.

Any info on the COO of Astro, Nova, or Sioux air tools? What about their quality these days?
Are there any air tools still made in USA?
Which do you reach for the most?
I figured I'd just get 1/2"
Thanks.

I have been extremely happy with every Astro air tool I own, and I use them hard. My welding supply salesman sells the **** out of Astro air drills. He says they are very reliable. I plan to purchase one soon.
I like air drills for large silver and deming drills and hole saws, because when it snags, the drill stalls and your wrist lives, unlike a hole shooter which takes you for a ride.
I primarily use my air drills for aluminum at work. I use pan american, sioux , and avro. Several other guys have Dotco, Cp and astro. They all range in price, you get what you pay for, the more expensive ones are quieter which is really nice if you use it a lot. The manufactures offer different speeds for the different materials, just buy the speed for the material you will drill the most so you save your drill bits. I do have 1/4 inch, 3/8s and 1/2 inch sized chucks.
There are a few that have them. A lot of the time guys will get them to start with cause some of the drills can get pricey. I don't see why it wouldn't well for a home garage.

Anyone using an air drill for spot weld drilling on 60s cars. I'm thinking getting one to use with endmill style bits, and expect to have bunch to drill in my future. May also use for welding projects up to 1/4" mild steel. Looking Recommendations for RPM, brand. I want the torque, quieter is better and efficient air consumption. Thanks!
I've drilled a lot of spot welds with air drills. The best cutters are Rotabroach or Blair tools. They have a spring loaded pilot pin that will pilot on a center punch mark and cut around the outside of the spot weld. These need to be run at a slower speed, and a 3/8 capacity air drill works best. Do yourself a favor and look for one that has a real quality Jacobs keyed chuck. Anything else will eventually let you down, and a Jacobs can be rebuilt after long service. Top line tools would be Dotco, Sioux, IR, and CP. IR and CP have both inexpensive and heavy duty versions, so be careful with them.
I pm'ed the astro rep about buying the 3/8 one, thanks for the advice!![]()

Feebay is by far the best deal for all those looking at their 3/8 one, less than $50 shipped.![]()
Why air powered? I have never understood them. That being said, I own an older snap on one. I do not remember ever using it. Maybe I should try it out.
My air drill is probably rusted tight. By a good cordless and you will never use air again.
Man, so much air drill hate around here!
I have 12v, 18v & corded drills, but would still go for my air drill most of the time working in the truck shop (drilling frames for boxes, replacing fenders, drilling out rivets, etc). If it's a tight spot, you already have an air hose, and you know you're going to be there for a while, they are 10x better than holding a 18v battery over your head until your arm starts to fall asleep.
That said, I had an older IR 3/8 that worked great, but upgraded to a used reversible 3/8 Matco (not sure if IR or CP era) that has been a big improvement. Matco Model number is MT1789. There are a couple on ebay right now averaging under $60 used. For 1/2", I used a coworkers' MT1727 with the handle, and it was just a bigger version of mine. Both are made in Japan, parts are readily available online.
Reversible is the way to go, from bits getting stuck to reverse threaded bits, it is just a big help when you need it. I added an air regulator to the intake so I could slow it down and not burn up my step bits.
I would never hesitate to buy one used, just open up with an adjustable wrench, pull out the rotor, wipe down and check the vanes & barrel. Wipe off and throw some grease on the planetary gears, and if the bearings are smooth just toss it back together.

I think I have about 30 air drills. I bought them all used for about $10 to $15 each. They are all industrial brands like Cleco, Dotco, ARO, Soutter, Atlas Copco, Rockwell International, Jiffy, Buckeye, and IR (industrial version). I like Cleco and ARO best.
Here are my pneumatic drill collection. There are three more not shown. I gave them to my brother and BIL. The most expensive one in the lot is the HF angle drill on top right corner of the first image. Before I bought the angle drill to the left of the HF drill, I need an angle drill pronto to drill out a broken bolt in the engine bay. I didn't have a 20% coupon and it was not on sale, so I paid full price for the HF drill (~ $40). Right now, I don't want to sell them.
