Does it come with a battery and charger?

No. The XAG04Z is a bare tool, so you need a Makita 18V LXT battery and charger, or an existing LXT kit.

Can it use both 4-1/2-inch and 5-inch wheels?

Yes. It accepts both wheel sizes, with a 5/8-inch-11 spindle for standard accessories.

How does it compare with a corded grinder?

It trades some sustained power and runtime for cordless freedom. For heavy continuous grinding, a corded grinder still has the edge.

What is Automatic Speed Change?

It is electronics that adjust speed and torque as load changes, helping the tool keep working instead of stalling.

Which batteries give the best runtime?

Larger-capacity LXT packs give the longest runtime. Compact packs make the tool lighter but drain faster.

Is it good for cutting rebar and pipe?

Yes. With the right cut-off wheel it handles rebar, pipe and threaded rod well, which is a common use owners report.

About the Makita XAG04Z 18V LXT Lithium-Ion Brushless Cordless 4-1/2" / 5" Cut-Off/Angle Grinder

The Makita XAG04Z is an 18V LXT brushless cordless cut-off/angle grinder for grinding, cutting, and sanding metal, masonry, tile, pipe, and conduit. It is sold as a tool only, without a battery or charger. It works with Makita 18V LXT slide-style batteries that have the Star symbol.

An electronically controlled brushless motor matches torque and speed to the job and uses battery power more efficiently. Automatic Speed Change adjusts speed and torque as the load changes. Star Protection Computer Controls let the tool and battery communicate to help protect against overloading, over-discharging, and overheating.

Active Feedback-sensing Technology shuts off the motor if the wheel is suddenly forced to stop. Soft start reduces startup snap, and anti-restart protection helps keep the tool from powering on when a battery is inserted with the switch locked on. The grinder has a slide switch with lock-on and a rubberized soft grip. Spiral bevel gears transfer power, internal cooling helps performance, and wire mesh intake covers help keep debris out of the motor.
