I walked in and started looking through the Mac Tools truck the other day and one of the techs I work with walked in to pick up an order. He had ordered a Mac Tools 1/2 impact (AWP050) and I laughed and told him that was a funny looking gun. Then he said go ahead and laugh this is the strongest 1/2 air impact on the market. I asked if it was stronger than Snap-On's since I own one. He said yes
and he showed me the torque specs on the box which were 1250 ft lbs.
When I saw that I felt like I got ripped off thinking I bought the best. As of now I'm looking to get a 3/8 air impact I was thinking Ingersoll Rand 2115TiMAX but Mac's 3/8 impact (AWP038) has 525 ft lbs
That's pretty insane for a 3/8. I'm looking for the best in class power and reliability. If anyone has good advise to give to a brother about the Mac Tools AWP 3/8 (AWP038)1/2 (AWP050) or 3/4 (AWP075) Titanium series impacts it would greatly be appreciated. Because I couldn't find reviews or customer report information elsewhere. Thank you

shop around for the best deal. 
But seriously, both ARE made by SBD (Stanley Black & Decker) 6 vs 1/2 Dozen.
