Mastercool’s E-Z tube cutters offer the latest “Reduced Friction” technology! Our reduced friction design incorporates ball bearings into the cutter wheel, tube rollers and a control knob. Reducing the resistance in these high friction areas allows the cutter to roll fast and easy as it slices through the tube. The “Reduced Friction” design is sure to save time and reduce fatigue! 72034: Replacement cutting wheel for 72035
