6 Professional Uses of Dewalt Multi-Tool Blades

Estimated read time 5 min read

Multi-tool blades have various professional uses due to their increased versatility. Considered to be the best power tool by many professionals, oscillating multi-tools are popular among remodeling contractors, DIY handymen, construction specialists, and woodworkers.  

These flexible, portable, and compact power tools are compatible with various interchangeable blades. This perk allows you to use a multi-tool for various applications, such as polishing, grinding, scraping, cutting, sanding, etc.  

The tool oscillates or vibrates the blade back and forth at high speeds to get the job done. Since it relies on oscillation, a multi-tool is much safer than conventional tools like jigsaws, reciprocating saws, and circular saws. 

Multi-tool blades will cut through virtually anything, including building materials like fiberglass, plastic, mortar, cement, drywall, metal, and wood. They can also access specific places, including awkward angles, tight corners, and narrow spaces.  

Let’s discuss the top six professional uses of multi-tools to see how they can help with everyday jobs.  

1. Trim door casings

You often need to trim door jambs and casings to install a new floor and accommodate the new flooring. Dewalt multi tool blades are perfect for this job. Since they are interchangeable, take a flush-cutting wood blade and attach it to the tool.  

Plunge-cut through the door casing by taking the blade to the flooring piece. Dispose of all severed pieces of wood and let the new flooring slide beneath the door casing. 

2. Sand wood smooth

One of the best things about multi-tools is the range of blade attachments. There’s an attachment for every application you can think of.  

When it comes to sanding, Dewalt offers various sanding attachments for uses like clearing topcoat finishes, polishing wooden surfaces, and smoothing wood fillers and wood. The attachable accessories are compatible with hook-and-loop abrasives, making it simple to change sandpaper.  

3. Cut plumbing pipes 


Dewalt offers multi-tool blades for effectively cutting through galvanized metal, plastic, and copper pipes. The blades are adjustable to various angles making the multi-tool a compact solution for handling jobs in tight spaces, including under floors, ceilings, behind walls, inside cabinets, and more. 

4. Remove old paint 

Multi-tools are so versatile when removing old, blistered, and loose paint quickly and effectively. Attach a steel scraper blade and apply it to the surface where you need to remove old paint. After you remove the paint, switch to a sanding pad to polish the metal or wooden surface. 

5. Salvage room moldings  

Many people have faced the problem of damaged wood moldings since it’s virtually impossible to pry them off without leaving permanent damage. Thankfully, a multi-tool can make that trouble go away.  

Take a fine-tooth metal-cutting blade and install it on your multi-tool. Make a clean cut by slicing through multiple layers of finishing nails, old caulking, and dried paint to salvage your room moldings without leaving a mark on them. 

6. Grind out grout  

Multi-tool manufacturers provide an assortment of attachable accessories, such as a carbide-grit grout-removal blade. Install it on your tool and apply it to the joints between wall tiles and floor tiles to grind out grout from them.  

Since multi-tool uses back-and-forth oscillation instead of a spinning mechanism, you won’t have to clean grout dust after you finish the job. 

Additional multi-tool applications 

Here are additional uses for a multi-tool to consider.  

Cut drywall openings 

The Dewalt multi-tool allows you to accurately and efficiently make holes in ceilings, plaster walls, and drywall. Outline the cutting surface and use a metal or wood-cutting blade to bore a hole in the surface.  

A multi-tool can plunge through the surface with extreme precision, allowing you to leave the wires or pipes buried behind intact.  

Grind away mortar 

With the multi-tool, removing hardened cement-based mortar from surfaces like subfloors is as easy as possible. Use a triangular-shaped carbide-grit rasp to grind away rock-hard adhesives, cement, and mortar.  

The carbide-grit rasp is super coarse and provides enough power to pulverize the rock-hard mortar and turn it into dust.  

Get rid of the old caulk.  

Removing hardened, old caulk is every contractor’s nightmare. However, the multi-tool provides a sharpened steel scraper blade that can cut through the most stubborn, hardest caulk you’ve ever seen.  

You can use the multi-tool to remove old caulk from various surfaces, including doors, windows, backsplashes, counters, sinks, and tubs. 


 As its name suggests, the multi-tool is a multipurpose power tool you can rely on in many situations. These professional uses are just the tip of the iceberg, as there are many more applications where the multi-tool excels. Buying an oscillating multi-tool is a long-term investment that gets you a grinder, sander, scraper, cutter, and saw in one compact power tool. Aside from multiple purposes, the multi-tool also offers access to inaccessible places, allowing you to save time on completing complex projects without exceeding deadlines. 

Finally, whenever you are working with potentially dangerous equipment, be sure to take the necessary safety precautions. Having a safe working environment is the most important thing.
