Is the Milwaukee 2990-20 worth it over a corded chop saw?

If you cut steel away from power or move between floors, yes. It matches a 15 amp corded saw on RPM and removes cord and generator hassles. If you cut in one shop spot all day, a corded saw costs less and never needs a battery.

What battery does it need, and how long does it run?

It takes any M18 REDLITHIUM pack, but High Output packs give the best runtime and power. Expect noticeably shorter cutting per charge on compact 2.0 or 3.0 Ah packs than on 8.0 or 12.0 Ah High Output.

What comes in the box?

The 2990-20 is tool-only: the saw and its standard accessories, with no battery, charger or case. You supply an M18 battery, a charger and a 14 in. abrasive wheel.

Up to 5 in. with the correct abrasive wheel installed. Depth depends on wheel diameter and wear, so a worn wheel cuts less than a fresh one.

Does it use standard 14 in. abrasive wheels?

Yes, it takes standard 14 in. abrasive cut-off wheels. Match the wheel to the material, such as metal or stainless, and check the wheel's max RPM rating against the saw's 4,000 RPM.

Watch for Milwaukee promotions and bundle deals that pair the bare tool with a High Output battery, which often beat the tool-only price per usable setup. Prices move with seasonal sales, so compare across stores before buying.

Our take on the M18 FUEL 18-Volt Lithium-Ion Brushless Cordless 14 in. Abrasive Cut-Off Saw (Tool-Only) - 2990-20

The Milwaukee 2990-20 is a cordless 14 in. abrasive chop saw built on the M18 FUEL platform. Its brushless POWERSTATE motor spins up to 4,000 RPM, which Milwaukee rates as equal to a 15 amp corded saw, and REDLINK PLUS electronics guard against overload, overheating and over-discharge. It cuts up to 5 in. deep with the right abrasive wheel and runs on M18 REDLITHIUM batteries sold separately. It is a tool-only kit, so budget for a battery and charger if you are not already on the M18 system.

What reviewers say

Owners treat the 2990-20 as a genuine corded replacement for rebar and steel work, praising the power and cut speed on M18 High Output packs. The main complaints are runtime on smaller batteries and the weight of the bare tool.

Pros

Near-corded cutting speed on steel and rebar
Solid build and smooth, controlled cuts
REDLINK shutdowns protect the tool in heavy use

Cons

Short runtime unless you use High Output batteries
Heavy for one-handed carrying
Sparks and grit spread widely without a stand or guard setup
