Did you know that copper pipe has been used for water supply since ancient Egypt? Pharaohs used copper to channel water for bathing, long before oscillating tools were even a fantasy. Today, we’ve traded bronze chisels for lithium-ion batteries, but the goal remains the same: a leak-free, beautiful pipeline.
Pop culture holds a soft spot for the oscillating tool, too. It’s the secret weapon of every home renovation TV show star, from Mike Holmes to the Property Brothers. When they need to cut through a stubborn copper line without damaging the tile, that little rectangular blade is their quiet hero. It’s the ninja of the toolbox—unassuming but deadly effective.
Fun fact: The oscillating tool was originally invented in the 1960s by a German company, but it didn’t become mainstream until the 1990s with the Fein MultiMaster. Now, it’s so cheap that you can buy a decent cordless version for the price of a good dinner—which you should probably treat yourself to after the plumbing project.
12 DIY Projects That You Can Do With An Oscillating Tool
Safety and Style
Don’t forget your safety glasses and a dust mask. Cutting copper produces tiny, sharp flakes that can become embedded in your skin or eyes—not a chic look. Also, the blade gets hot; let it cool for 30 seconds between cuts if you’re doing a production run.
For a professional finish, debur the inside and outside of the cut pipe with a deburring tool or a simple file. A ragged edge can cause turbulence in water flow and premature corrosion. A quick swipe with 220-grit sandpaper removes the last burr and leaves a surface ready for soldering or pressing.
