The Ingersoll Rand 125-A Air Needle Scaler is great for cleaning and removing paint, rust, dirt, or weld slag. Building on the foundation of the popular 125 model, the updated tool's needle spring has been re-engineered to provide a significant increase in durability. This highly versatile scaler can be used with 1/8-inch round needles (qty. 19) or with chisel attachments to match up with many of your surface preparation needs. The 125-A now delivers more blows per minute – 4800 - and more than double the work life of its predecessor, making it a great dependable and economical choice for prepping surface work.
