Overview
The Milwaukee 2830-20 is an 18-volt cordless saw specced with an 8-inch cutting capacity and a high speed steel blade, running at 5800 RPM. The combination of blade material and speed points toward metal-cutting duty rather than wood framing.
Milwaukee's M18 lineup includes several saw formats, and the spec mix here (a high speed steel blade, 8-inch capacity, and RPM rather than strokes-per-minute) lines up with a metal-cutting circular saw rather than a reciprocating saw or band saw. At 270 watts of motor power and a listed weight of 4.5 kilograms, it reads as a job-site tool meant to be carried, not bench-mounted. The listing does not spell out bare-tool versus kit weight, so buyers should confirm whether a battery and charger are included.
- 8-inch cutting capacity
- High speed steel blade material
- 5800 RPM rated speed
- 18-volt M18 battery platform
Who it's for
Suited to tradespeople who need to cut metal stock such as conduit, angle iron, or strut on site without running a cord. Less relevant for general wood carpentry, where a standard circular saw with a carbide blade is the usual choice.
Strengths and trade-offs
Drawn from this product's published specifications.
- Cordless 18V metal-cutting capability
- 8-inch cutting capacity
- Kit contents not specified
- Not intended for wood framing cuts
Performance notes
Running at 5800 RPM with a high speed steel blade, the saw is geared for cutting through metal without the sparks and heat buildup of an abrasive cutoff wheel. The 18-volt M18 battery platform trades some runtime for the convenience of cordless operation on jobs where a power outlet is not close by.
