Ingersoll Rand IR231 Air Impact Wrench review

The Ingersoll Rand 231 air impact wrench is a classic tool that has been around for well over 20 years. This is a classic design that has largely been unchanged by Ingersoll Rand over the years. It is a twin hammer design (also, there is a fitting to grease the hammers) and is high speed. Only a small amount of grease is needed even with heavy use. Simply apply the grease through the pin greaser and away you go. Be careful not to over grease your tool, too much grease will slow the impact and its hammers.
Overall, the tool is well balanced and not overly heavy. It fits well into your hand and has a light trigger pull. (If your looking for a light impact, try the Ingersoll Rand IR2135Ti Titanium air impact wrench) This tool has the adjustable torque setting built right into the forward/reverse button. This feature allows the operator to adjust the torque with your thumb. Very handy.
To sum it up, the Ingersoll Rand 231 air impact wrench is a solid performing air tool. You can't go wrong with this one. It has surprising power and speed and is built like a small tank. The IR231 delivers 1200 blows per minute and develops an average of 390 foot pounds of torque on about 5 CFM at 90 PSI of air. Good, solid performer.
