Electric brakes can stop a grinding or cutting wheel in less than two seconds so that you can work as quickly as possible.
If the wheel is suddenly forced to stop moving, active feedback-sensing technology (aft) turns off the motor to save power.
Automatic speed change technology adjusts speed and torque while the machine is running to get the best results.
It doesn’t have carbon brushes, so the BL motor runs cooler and more efficiently for a longer time.
A powerful BL Brushless motor is electronically controlled to make the most of battery power for up to 50% more run time per charge.
Makita’s 18V LXT Lithium-Ion Brushless 4-1/2″ Cut-Off/Angle Grinder with Electric Brake gives you the power of a corded grinder without the cord (XAG09Z, tool only, batteries and charger sold separately). It has a Makita brushless motor that gives it more power, speed, and run time. It also has a longer tool life. For the most difficult jobs, Makita’s unique Automatic Speed Change Technology automatically adjusts speed and torque to get the best results. The XAG09Z has an electric brake that stops the wheel in 2 seconds or less when the switch is released. This makes it even easier to get around. The XAG10Z can be used to grind, cut, and sand a wide range of materials, like tile, concrete, pipe, conduit, and more. It’s part of Makita’s expanding 18V Lithium-Ion system, which is the world’s largest cordless tool system that runs on 18V Lithium-Ion slide-style batteries, which are the most powerful batteries in the world. 18V lithium-ion batteries from Makita have the fastest charge times in their categories because they work more and don’t have to wait as long to be charged. For better tool performance and longer battery life, Makita came up with Star Protection Computer Controls. Star Protection is a type of communication technology that allows a Star Protection-equipped tool and battery to exchange data in real time and keep an eye on things while they’re being used to make sure they don’t get too hot, get too full, or get too low. For more versatility, the tool can also be powered by Makita 18V LXT and Compact Lithium-Ion batteries that have the Star Symbol on them. This means that the battery has Star Protection inside.
If you already have a Makita tool, this is the angle grinder to buy. XAG09 looks like their most recent brushless model, though.
These have electric brakes that stop the disc quickly after you turn them off. Another feature is that it doesn’t allow people to kick you back (electronic torque control).
A lot of people have written good reviews about the XAG03 model on Amazon, but it’s an older model that doesn’t have those two things.
