In “Oscillating Multi-Tool Tips and Tricks,” Stumpy Nubs dives into the functions, uses, and various blades for the oscillating multi-tool, a versatile power tool in woodworking and general construction.
The video begins with a historical note, explaining the explosion of multi-tool availability after the expiration of the original patent around 2008.
The Video Is Broken Into The Following Chapters:
1) Make Plunge Cuts
2) Plunge Blades
3) Wood Cutting Blades
4) Bi-Metal Blades
5) Sander Attachments
6) Turn The Blade Backwards For Storage

Stumpy emphasizes the importance of understanding the tool’s functions, highlighting that many users don’t fully utilize its capabilities.
The multi-tool is not just for small cuts; proper use includes starting cuts with the corner of the blade for control and using the blade to score before making deeper cuts, aiding in accuracy.
A key feature of the oscillating multi-tool is plunge cutting. Stumpy advises using a wood block as a guide for straight cuts, noting that the sandpaper on the guide block can help hold it steady.
The block also helps maintain a perpendicular angle for more precise cuts. Users should be aware that dust-filled teeth can lead to slower cutting and potential drifting if they force the tool, hence patience is essential.
For accurate cutting, Stumpy suggests marking the depth with tape on the blade as an alternative to using the scales provided on some blades.
He explains that some blades have extended wings that aid in making plunge cuts and can also be used for curved cuts, similar to using a jigsaw.
When it comes to cutting metal, slower speeds and less pressure are critical to preserving blade life.
The same principle applies when cutting hardwood versus softwood; a gentler approach will yield better results.
Stumpy also gives a brief overview of the types of blades:
- Wood cutting blades: Larger teeth and space between them for efficient sawdust clearance.
- Bi-metal blades: Suited for cutting both non-ferrous metals and wood with embedded metals like nails.
- Carbide tooth blades: Excellent for metal but also applicable for wood and plastic, with greater durability and heat resistance.
He also touches on abrasive style blades with carbide or diamond chips for tile and concrete, and scrapers, which are useful for removing glues and adhesives.
He suggests repurposing dull regular blades as scrapers.
Stumpy doesn’t recommend the sanding attachments for precision work due to their limited range of motion and tendency to leave marks.
However, they can be useful for rougher work such as paint removal. He concludes with a storage tip: turn the blade backward to prevent damage.
