The Bosch 18V X-LOCK Lithium-Ion Brushless Cordless 4-1/2" – 5" Connected-Ready Angle Grinder Kit w/ CORE18V 8.0 Ah Performance Battery (GWX18V-50PC) features a tool with the X-LOCK mount, offering a wheel change interface that's up to five times faster than conventional interfaces. There’s an audible snap when mounting an X-LOCK Wheel on an X-LOCK grinder. The wheel mounts properly without the need for a spanner wrench or flange nuts. The wheel is released from the grinder with the pull of a lever. The grinder’s brushless provides greater efficiency that maximizes runtime and productivity. It has power equivalent to a 10-amp corded grinder.

The grinder provides an X-Brake, which helps provide a rapid stop of the wheel when the switch is turned off. It also includes other advanced electronics, such as drop control, KickBack Control, restart protection and soft-start technology. The grinder has connected-ready capability, supplying an interface that works with the optional Bosch Connected Tool Module to link to the free Bosch Toolbox app.
