5 Types of Jobs a Multi-Tool Makes Easier

By Fran J. Donegan

If you’re like many people, you won’t know you need a multi-tool until you actually have one. They have dozens of uses for all sorts of odd jobs, some of which won’t be apparent until you have the tool in your hand.

Multi-tools are hand-held, corded or battery tools that have oscillating heads. The head moves back and forth in a very tight arc. Fit a cutting blade or some other attachment to the head and you can cut, shear, grind and sand in a very small space. Its small size is one of the reasons it is so useful: It can fit in spaces where larger tools cannot. And the tools can cut through most materials, including wood, drywall, PVC, foam insulation, carpeting, metal and more. If you have a favorite tool manufacturer, there is a good chance they make a line of multi-tools.

Here are some situations where you will find a multi-tool useful.

Removing Hard-to-Remove Materials

When it is time to re-grout a backsplash or a tub surround, use a multi-tool fitted with a grout blade to remove the old material. The thin, rigid blade will fit between tiles, and the mild vibration of the tool makes it easy to control.

To remove carpet adhesive or any hard-to-remove adhesive, use a multi-tool with a scraper blade. They also come in handy for digging hardened caulk from joints.

Working in Tight Spaces

The small handheld design of multi-tools can give you cutting or grinding power in cramped quarters. With a metal cutting blade you can trim copper plumbing lines with ease. You can also use the tool to loosen corroded sink nuts that you can’t get to budge with a wrench. The tools also do a quick job of cutting through the nuts that hold toilets to the floor, as well as the nuts that attach the tank to the bottom part of the toilet.

The compact size of a multi-tool combined with its aggressive cutting action makes it a great choice for cutting pipes beneath sinks.

Making Plunge Cuts

Whether you need to cut through drywall to install an electrical receptacle box or hardwood flooring to install a vent for ductwork, you can make clean cuts without marring the surrounding surface. By plunging the blade right through the face of the material (rather than approaching from an exposed edge), you’ll save material, have less mess to clean up and fewer repairs to make.

The ability to make plunge cuts means a multi-tool saves time, reduces waste, and makes less of a mess than other cutting tools.

Trimming Door Casings and Baseboards

Adding a new floor often means it is necessary to trim the door casings and baseboard to get a professional looking fit. Use a sample of the new flooring as a guide to make the cut. The varying size of the accessory blades gives you the option of using a broad blade to make larger cuts or using a narrow blade for more intricate notches. Blades are available for cutting softwood, hardwood, and a wide range of other materials.

Flooring installation typically requires cutting door jambs to allow for the thickness of the floor material. A multi-tool can make flush cuts quickly—just use a scrap of the flooring as a thickness gauge.

Sanding Detailed or Awkward Areas

You would not use a multi-tool on large surfaces, but you can accomplish detail sanding in very tight spaces. They are also good on narrow areas like window mullions. You’ll find the same range of abrasive grits for multi-tools as you will for other sanding tools.

For detail sanding, the narrow size of a multi-tool can access tight spaces, and the triangular points can sand inside corners.

They’ve earned the name “multi-tools” for the versatility they bring to any number of jobs. A multi-tool probably will not replace your other tools, but in some situations, you may find it is the best tool for the job.
