Money-saving plastic pipe reamers (also known as socket savers and/or hub savers) 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 standard 1/2 in drills. PPR socket savers work great for vent lines, drain lines, PVC unions and water lin. Carbide cutting insert on socket saver provides a cutting edge on each side. Rotate the socket saver's cutting insert before replacement and receive three additional cutting edges.
