Plumbing — FAQ
What size tubing cutter do I need for home plumbing?
A 1/8-inch to 1-1/8-inch cutter handles most residential copper and PEX. For whole-house repipes, get an adjustable model up to 2 inches. If you only cut 1/2-inch and 3/4-inch pipe, a two-cutter set saves adjustment time.
Can one cutter handle both copper and plastic pipe?
No—metal wheels crush plastic, and plastic wheels dull instantly on copper. Use a dedicated copper cutter for metal and a plastic-specific cutter for PEX, PVC, and CPVC. The Mutt Tools cutter handles all plastics but won't cut copper.
How often should I replace the cutting wheel?
Replace wheels every 200-300 cuts on copper, or when cuts require excessive force. On PEX and PVC, replace every 100 cuts. A sharp wheel cuts in 3-5 rotations; a dull one takes 10+ turns and deforms pipe.
What's the difference between standard and compact tubing cutters?
Compact cutters measure 3-4 inches long and fit tight spaces but require more rotations. Standard cutters are 6-12 inches, providing leverage for faster cuts. Use compact models between joists; standard models for open work.
Are quick-release tubing cutters worth the extra cost?
Absolutely for professionals. They cut setup time by 50% and allow one-handed operation. DIYers doing under 10 cuts per year can save money with standard screw-adjust models. The Reed TC3QP proves the value on large jobs.
How do I maintain my tubing cutter for maximum life?
Clean debris from rollers after each use, lubricate the feed screw monthly, and store in a dry place. Never force a dull wheel—replace it immediately. Check for frame cracks quarterly if used daily. Keep the wheel alignment true to prevent pipe scoring.
