With new advances in technology constantly being developed by Ingersoll Rand, it’s important to keep in mind the strong legacy of professional tools that we here at Ingersoll Rand have been providing to professional technicians year in and year out. Ingersoll Rand invented the impact in 1934, and one of our longest-standing tools is the Classic 231C Impactool. Over the years, advances in technology and changes in industry standards gave us the opportunity to expand our product offering and develop new tools. However, the Classic 231C is still the most popular tool in its class. Introduced over 25 years ago and continuously refined, it offers the sheer power and performance features to tackle the toughest jobs with ease - as well as proven durability and economy. Some of the features of the 231C include an adjustable power regulator, pressure-feed lubrication, and an easy to service two-piece construction.
