Overview
Milwaukee built the M18 FUEL Saw around its 18V battery platform, spinning an 8 inch blade at 3900 RPM inside a metal housing.
The M18 FUEL name points to Milwaukee's brushless motor line, which trades a cord for battery power without the RPM drop older cordless saws had. The 8 inch capacity and metal build suggest a tool meant for repeated job site cuts rather than occasional home use. Listed dimensions on this unit look like a data error rather than a real footprint, so they are left out here.
- 18V M18 FUEL power system
- 3900 RPM motor speed
- 8 inch blade capacity
- Metal housing construction
Who it's for
Fits tradespeople already invested in Milwaukee's M18 battery ecosystem who need an 8 inch capacity cutting tool without running a cord. Less useful for someone starting from zero on batteries, since the pack and charger typically cost extra.
Pros and cons
- Cordless 18V M18 battery platform
- 8 inch cutting capacity
- Durable metal housing
- 3900 RPM brushless motor
- Battery and charger likely sold separately
- Roughly 5.8 lb for extended one-handed use
- Listed dimensions appear unreliable
Performance notes
The brushless motor draws from an 18V M18 pack and spins the 8 inch blade at 3900 RPM, a combination aimed at cutting metal or similar material rather than deep ripping. The metal housing adds durability, and at roughly 5.8 pounds (92.49 ounces) the tool sits in the middle of the weight range for one-handed cordless saws.
