Makita XAG03Z 18V LXT Li-Ion 4-1/2 in. Brushless Cut-Off/Angle Grinder (Tool Only)

Makita's newest cordless solution for metalworking is the XAG03Z 18V LXT Cordless Lithium-Ion 4-1/2 in. Brushless Cut-Off/Angle Grinder. It is powered by a brushless motor delivering 8,500 RPM for faster grinding with soft start to suppress start-up reaction for smooth start-ups and longer gear life. This grinder features Automatic Speed Change Technology, which is engineered to adjust speed and torque during grinding or cutting applications for optimum performance, even under heavy load. Additionally, the motor is electronically controlled to optimize battery energy use for up to 50% longer run time per charge than similar non-brushless tools. The XAG03Z also has a slide-switch with lock-on, a rubberized soft grip, a 3-stage LED gauge to indicate battery charge level, and a compact, ergonomic design to reduce fatigue during prolonged use.
  • Automatic Speed Change technology adjusts speed and torque during operation for optimum performance.
  • Brushless Motor eliminates carbon brushes, enabling it to run cooler and more efficiently for longer life
  • Brushless motor is efficiently and electronically controlled to optimize battery energy to match torque and RPM to the demands of the application, as well as increase run time by up to 50%
  • Rubberized soft grip provides increased comfort on the job
  • 3-stage LED gauge indicates battery charge level
  • Soft start suppresses start-up reaction providing smooth start-ups and longer gear life
  • Spiral bevel gears for smoother rotations and a more efficient transfer of energy

5 out 5 men would recommend!
I’ve had the old push style on switch, and then I got a newer one with a paddle style, and this is the latest for me (still have the others too). I mostly use it for fabbing metal stuff on vehicles, and this has become my favorite grinder. It has plenty of power for grinding and cutting, yet I don’t have to worry about plugging it in or accidentally nipping the cord. I’ll likely get another if these go on a holiday sale anywhere.

beats my corded one
put this to use first day, did a whole house with new baseboard, so had a lot of cutting to do, the cutting wheel lasted longer than a dewalt one I had used, easy to use and handle, was powerful and worked as you would expect a Makita tool would, great.

Happy cutting
I used it with a diamond blade to cut the mortar between my brick planter bed! Like butter!

Since it is BL, and since it is a Makita... the work is so smooth that you can actually do artwork with it!
Highly recommended
