Will it cut 3x framing lumber in one pass?

Yes. It cuts up to 2-5/8 inches deep at 90 degrees, which covers 3x stock. Depth drops at bevel angles, so check the bevel scale for angled cuts.

What does AUTOSTOP do?

It cuts power to the saw during a severe kickback event. It is a safety backstop, not a substitute for proper technique and a firm grip.

What is ONE-KEY for on this saw?

ONE-KEY lets you track the tool and manage it remotely, including lockout. It helps on shared jobsites and with tool inventory.

Is it a replacement for a corded worm-drive saw?

For most framing and ripping it is. It gives up some raw torque to a large corded worm drive but removes the cord and adds kickback protection.

What comes in the kit?

The kit includes the saw, a 12.0Ah battery and a charger. Check the box contents for the blade and wrench before your first cut.

Does it take standard 7-1/4-inch blades?

Yes, it uses standard 7-1/4-inch circular saw blades with the correct arbor size. Pick a framing blade for ripping and a fine-tooth blade for finish cuts.

About the Milwaukee M18 FUEL 7-1/4-in. ONE-KEY Rear Handle Circular Saw 12.0Ah Kit (2931-21HD)

The Milwaukee M18 FUEL 7-1/4-in. Rear Handle Circular Saw with ONE-KEY is a cordless saw for framing, ripping sheet goods and other heavy-duty jobsite cutting. It has a rear handle layout and the blade on the left side. It uses a POWERSTATE brushless motor and runs at 6,000 RPM under load.

It cuts up to 2-5/8 inches deep at 90 degrees, which clears 3x material in one pass. The bevel capacity is 53 degrees, with bevel detents at 22.5 and 45 degrees. Depth detents are at 1/2 inch, 3/4 inch and 1-1/2 inches. The shoe and guard are made of magnesium.

AUTOSTOP kickback protection shuts power off during a severe kickback event. REDLINK PLUS protects against overload, overheating and over-discharge. An electric brake stops the blade after the trigger is released, and an LED light lights the cut line. The saw has a rotational dust port, an included vacuum adapter and VACLINK wireless dust control with compatible extractors.
