Model number
3601-20

The Milwaukee M18 Compact Brushless 1/2 in. Drill/Driver is a compact 18V cordless drill built for tighter spaces and overhead work while still covering a broad range of general drilling and fastening applications. Milwaukee rates it at up to 550 in-lbs of torque and 1,700 RPM, with a brushless motor, two-speed drivetrain, and 1/2 in. all-metal chuck. At 5.7 inches long and about 2.3 pounds without battery, it sits below heavier premium M18 models while preserving compatibility with the broader Milwaukee M18 battery system.

§ FAQ

Does the 3601-20 come with batteries or a charger?

No. The 3601-20 is the bare-tool version, so batteries and charger are sold separately. It is most useful to buyers who already use Milwaukee's M18 platform.

How compact is the 3601-20?

Milwaukee lists it at 5.7 inches long and about 2.3 pounds without a battery. That makes it easier to control in overhead work and tighter spaces than larger full-size drill platforms.

How much torque does the 3601-20 provide?

Milwaukee's product overview calls out 550 in-lbs of torque and up to 1,700 RPM. That places it as a compact general-purpose M18 drill rather than a top-tier heavy-duty model.

What chuck does the 3601-20 use?

It uses a 1/2 in. all-metal chuck. That keeps it versatile for common drill bits while maintaining durability for regular jobsite or shop use.

Is the 3601-20 a hammer drill?

No. This model is a standard drill/driver without hammer mode. Buyers needing masonry drilling should choose a hammer-drill version instead.

Who is the 3601-20 best for?

It is a good fit for buyers who want an M18 drill with better balance, tighter-space access, and lighter weight than larger premium models. It is especially practical for general drilling and fastening rather than maximum-output drilling.
