I have a Milwaukee multitool and I use these aftermarket blades that I bought on Amazon in a pack of 50. In the stores they are more expensive, you will pay about $34 for a pack of three. Even if you buy it at Harbor freight it’s still expensive for a blade that will burn out pretty quickly on a job.I use the tool to cut through drywall trim work such as door jams, door casing baseboards. The blades last just as long as the name brands that you find in the store.
