This pipe notcher is designed to notch tubing from 3/4 In to 3 In tubing. Use any 1/2 In hand drill to power this professional Tubing Notcher. This notcher accepts all standard hole saws and is adjustable up to 50 degrees with the loosening of the bolt. Polyvinyl chloride, or PVC, pipe fittings and flanges connect with pipe to transport potable water, corrosive liquids, and sewage in industrial and commercial applications. Pressure-rated fittings have a numbered schedule rating. The higher schedule number indicates a thicker, stronger wall to handle higher pressures.
