What blade fits the Milwaukee MX FUEL cut-off saw?

The MX FUEL COS350 takes a 14-inch diamond blade with a 1-inch or 20mm arbor — same as gas-powered cut-off saws.

Can I use non-Milwaukee blades on Milwaukee tools?

Yes — Milwaukee tools use standard arbor sizes. Any quality diamond blade in the correct diameter and arbor will work.

What diamond blade works best on Milwaukee M18 grinders?

Milwaukee M18 grinders take standard 4.5-inch or 7-inch diamond blades with a 7/8-inch arbor. A segmented blade is best for concrete.

Best Diamond Blades for Milwaukee: By Tool

MX FUEL Cut-Off Saw (14”)

The MX FUEL COS350 is Milwaukee’s flagship concrete saw — a battery-powered 14” cut-off saw that rivals gas performance. It takes standard 14” blades with 1” or 20mm arbors. The VA 14” Ultra Value is our top pick for general concrete cutting. For asphalt, use the VA BD Asphalt.

M18 FUEL Grinders

All M18 grinders use standard 7/8” arbor diamond blades. Use segmented for concrete and masonry, continuous rim for tile, turbo for general purpose. See How to Cut Concrete with an Angle Grinder for technique.

The 9” M18 FUEL grinder is particularly useful for deeper cuts — a 9” blade cuts approximately 3.5” deep, nearly double the 4.5” grinder’s depth. See Best Diamond Blades for Concrete for size-specific picks.

Milwaukee-Brand vs. Aftermarket

Milwaukee sells diamond blades, but they’re priced at a premium. For the MX FUEL saw, any standard 14” blade with a 1” arbor works. The best diamond blades for Milwaukee tools are the same blades that work on Stihl and Husqvarna — it’s all standard sizing. Save the brand loyalty for the tools, not the blades.

For other brands: Stihl, Husqvarna, DeWalt, Makita.
