Can an Oscillating Multi-Tool Blade Cut Metal Safely?
Can a multi tool blade cut through metal?
Yes—an oscillating multi-tool blade can cut through metal, as long as you use the right blade type and match it to the metal you’re cutting. Standard wood blades will dull almost immediately on metal, but bi-metal or carbide-tooth oscillating blades are designed to handle nail-embedded wood, sheet metal, screws, bolts, and other tough materials.
What kind of metal can it cut?
With a quality metal-cutting blade, a multi-tool can slice through thin sheet metal, aluminum, copper pipe, small steel brackets, and protruding fasteners. Thicker steel stock is possible, but it’s slower and puts more heat into the blade—carbide tends to hold up better than basic bi-metal when the job is abrasive or extended.
How to get a clean cut (and avoid burning up blades)
Choose a blade labeled for metal (bi-metal for general use, carbide for harder or longer cuts). Run the tool at a moderate speed, keep steady pressure without forcing it, and let the teeth do the work. If the cut area is getting too hot, pause for a few seconds—heat is what kills blades and can discolor the metal.
When an oscillating multi-tool is the best option
Multi-tools shine when access is tight: flush cuts near walls, trimming a nail or screw head, cutting metal in place without removing surrounding material, or making controlled plunge cuts. For long straight cuts in thick metal, an angle grinder or reciprocating saw can be faster, but the multi-tool offers precision and control.

FAQ
What is the best blade type for cutting screws and nails with an oscillating tool?
Use a bi-metal blade for most screws and nails, and switch to carbide if you’re cutting hardened fasteners or doing lots of cuts where heat and wear build up quickly.
