The Micro-Cutter pneumatic cutter from Nu Flow can be used to clean and remove calcite and roots from the inside of a variety of pipes, including steel, cast iron and Orangeburg. The system rotates at approximately 2,000 rpm and will negotiate turns of 90 degrees in pipes down to 2 inches in diameter. It runs at 40 cfm and allows for multiple cutting heads to be attached that can cut through dense corrosion and root intrusion that is commonly found in drainlines. The drill tip has an adjustable spline available in various sizes to match different pipe diameters.
