Ingersoll Rand has long provided professionals with tools that deliver the power, durability, reliability, and value needed to get the job done right. Our 259 3/4″ Impactool? is yet another example of this legacy ? offering impressive performance, value, and convenience not found in competitive models.;The 259 is smaller and up to 2 pounds (.91 kg) lighter than other 3/4″ impacts in its class. Together with its improved weight distribution, this makes the tool easier to handle. And, unlike most other 3/4″ impacts, the 259 doesn?t require an upgrade to a 1/2″ (13 mm) air line. This means lower shop costs and greater convenience of use ? all without sacrificing tool performance.
