Review on Ingersoll Rand 115 Standard Minute Pneumatic: Enhancing Efficiency and Performance by Tom Beland

I've used this recently to rip off frozen nuts and bolts and snap a few rivets. He did his job. It's only rated for 2 cfm which my little 1hp 3 gallon supercharger can supply. (2.4cfm at 90psi). Most other air hammers require about twice that airflow to work at or near their capacity. The IR 115 air hammer allows me to do some housework, including car chores, without having to invest in a larger air compressor. Its short stroke allows it to work with less airflow but with less impact. It may take you a bit longer to get the job done and it may not work with anything that requires very hard hits. On the plus side, it has 5,000 BPM, which is much higher than most air hammers, and its shorter-than-typical length lets you get into tighter spaces. It's sold as a standard air hammer and if you're a casual user and currently own a smaller air compressor (but at least 2cfm at 90psi) this is the tool you need. In its category, this is a good deal and Ingersoll Rand quality. Be sure to use at least 3/8 inch diameter air hose.
