Ingersoll Rand needle scalers are offered in either industrial production or vehicle service grade. When choosing a needle scaler for your application be sure to weigh into your decision how hard you need the needles to hit the surface in contrast to how many times per minute (BPM). Ingersoll Rand needle scalers with a shorter stroke hit faster, but lighter and are best suited to surface preparation, light rust removal and coating removal. Models with a longer stroke hit harder but slower, and are designed to remove welding spatter and penetrate more deeply into neglected surfaces. From heavy slag to delicate surface clean up, Ingersoll Rand has a scaler for you and we can help you choose the right one. Please call (800) 608-5210 for technical support.
