Money-saving reamers are designed to clean out the old or broken pipe and leftover solvent cement from a fitting so the fitting can be reused. In this era of green living and recycling, try these reamers on PVC, CPVC or ABS to save time and material costs. Plastic Pipe Fitting Reamers fit into ½” electric or cordless drills. PPR reamers work great for vent lines, drain lines and water lines. The carbide cutting insert provides a cutting edge on each side. Rotate before replacement and receive three bonus cutting edges.
