The Makita XAG09Z is an 18V LXT brushless 4-1/2 in. / 5 in. cut-off/angle grinder with a slide switch and electric brake that stops the wheel in 2 seconds or less upon release, improving jobsite safety. The Makita-built brushless motor delivers 8,500 no-load RPM and runs up to 50% longer than brushed models. Automatic Speed Change technology continuously adjusts speed and torque under load for consistent performance across grinding, cutting, and sanding tasks.
What is the benefit of the electric brake on the XAG09Z?
The electric brake stops the grinding wheel in 2 seconds or less when you release the switch, versus 8 to 15 seconds for a wheel coasting to a natural stop. This reduces the window where an uncontrolled wheel can cause injury, and it speeds up disc changes on busy jobsites.
Does the XAG09Z use a paddle switch or a slide switch?
The XAG09Z uses a slide switch with lock-on for sustained operation. If you prefer a paddle-style dead-man switch that requires constant grip pressure, look at the XAG11Z, which is the paddle-switch variant of this same brushless 18V LXT platform.
What is Active Feedback-sensing Technology (AFT) on the XAG09Z?
AFT is an electronic safety feature that detects sudden wheel stalls or kickback events and automatically cuts motor power before the situation escalates. It is a layer of protection in addition to the electric brake and is standard on the XAG09Z.
Can I use cut-off wheels on the XAG09Z?
Yes, the XAG09Z accepts both grinding and cut-off wheels up to 5 in. diameter with a 5/8 in.-11 arbor. Use the cut-off wheel guard (sold separately or included with kit versions) whenever cutting to contain debris and protect the operator.
How does the XAG09Z compare to the XAG04Z?
The main advantage of the XAG09Z over the XAG04Z is the electric brake, which stops the wheel in 2 seconds or less for improved safety. Both share the same brushless motor, 8,500 RPM, 5 in. maximum disc capacity, and 18V LXT battery compatibility.
