I am new member and have not searched thorugh all the postings and any links or directions are welcomed. Please pardon the redundancy.

My first Impact wrench was a Mac Tools AW434M used on Ebay. It is a magnificent wrench From the weight and build to the sweet sound. Also the Proven Bullet Proof Twin Hammer Ingersoll Rand design. But when I could not remove a crank pulley bolt from a 1998 Toyota Tacoma 4 cylinder engine it was time for a new one.

The replacement is a Mac Tools 1/2" Composite Impact Wrench
Model Number AW480Q, which is a Nitrocat impact wrench. I have not gotten use to the feel and it doesn't seem as powerful as the AW434M. Which can be attributed to the noise and the twin hammer versus Twin clutch design. Again I have not come across a monster type of situation to test the impact.

The air compressor used is a Chicago Pneumatic (26 Gallon Tank) RCP-226VP with a Max Pressure: 130 PSI and 7.10 CFM @ 90 PSI. So the Impact wrench is getting enough air to work correctly.

Hope this is enough info.

:thumbup:I got rid of my Mac Tools AW480Q impact wrench and purchased a Snap On MG725.

I like the MG725, from the sound and feel of the tool. It honestly feels similar to the AW434M impact wrench, but more powerful.

Just like the twin hammer feel and sound, the combination seems more powerful and durable than the AirCat impact wrench.

There's two missing components to the "strength" of your impact wrenches.

You didn't specify what size hose you are using--you need a 3/8" or larger, but larger isn't necessary.

The other missing item is your couplings and fittings. If you want to maximize the strength of your gun, you need HVLP (high volume low pressure) couplings and fittings. Couplings are the largest (uh, should I say smallest) constriction in your hose--the smallest constriction in the course of your hose, and the largest thief of power. Milton type HVLP couplings are the most common that I am aware of. I use Milton type "V" couplings and fittings.

I didn't go into 1/4" NPT (National Pipe Taper) v. 3/8" NPT, but I suspect you figured that out already.

Oh, by the way, I use an Ingersoll Rand 2135TiMAX. IR is the definition of reliability and durability; you can easily rebuild them inexpensively, and if necessary, they're available cheap on eBay if you don't mind buying used. It's not uncommon to run these guns routinely at 120 to 150 PSI. Most two-stage compressors fill their tank at 175 PSI.

If you're gonna use it everyday, I'd get the 2135QTiMAX. They're not as quiet as the Aircats, but they're pretty close, and they're plenty quiet as far as I'm concerned. The 2135Ti or 2135TiMAX in the "Quiet" series are more difficult to find used.

I hope this helps.

Get an IR Ti series... I have a 2135QTiMAX as well, and it is a beast! IR is very durable, as well, and will last a good long time, to say the least.

Other make great stuff, but IR sets the standard, and they set it really high.

Thank you for your inputs:bounce:

My current hose assembly is: 25 foot 3/8" Legacy Flexzilla Hose and Couplers are Legacy ColorConnex Type D (industrial fittings) with a 1/4 in NPT. I use two couplers, one at the compressor and the other at the end of the hose.

Future plans are to upgrade fittings to Milton HVLP couplers for all my connections and a inline air filter system that has a desiccant dryer that will remove water and water vapors.

Can I use larger fittings on my MG725? Such as a 3/8 NPT?
