Air Chisel

Hi all,
I am in the stone masonry buisness. As some of you may know, stacking rock requires a decent amount of chiseling. As i was chipping away this afternoon, i look at my partner, and tell him, "well, you know what we need, is an air chisel!" So I am researching it, and trying to find out if it is the proper tool for the aplication, and also what's a good buy, and what is not.

Looking for something pretty industrial strength, or commercial grade. For all types of stone. I've looked on Ebay, and they seem pretty reasonable. If i were to buy a package deal with 4 chisel bits, whould those chisels that ussually come in those packages hold up for chiping stone? If not, i can go with just a single piece set, with the air hammer, and find a supplier for the bits i need.

NEXT...and most important....If i were to get an air chisel, i would need an air compressor. It seems a good average for CFM on this type of tool is 4 CFM. On that note, what kind of specs do i look for in a compressor? I am not familiar on the sizes of tanks needed, or the CFM. Basically looking for somehting that is suitable for the job, and also would be able to run a Framing gun.

Anyway, thanks in advance. (chip chip)

If you look at different air compressors you would be best to pick the one that produces the highest CFM while being able to be used on a normal 15 amp 120 volt circuit.
This would likely be around 5 or 6 CFM.
This size would be enough to run most air nailers as well.

I wouldn't be too concerned about the size of the air tank as the tank only determines how often the compressor cycles and does not affect the unit's capacity.

I personally use an air chisel quite a bit on metal but can't say how it would work on brick. It has quite a forcefull effect but most chisels have an adjustment for the airflow.

You might want to buy an inexpensive one to see how well it works for you.
