Bosch's X-LOCK Wire Wheels feature the X-LOCK mount and offer a wheel change 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. This stiff stringer-bead knotted wire wheel features carbon steel with extremely narrow tufted faces for confined areas such as cross-country pipelines and pipe fabrication, as well as brusing expansion joints and narrow grooves. Bosch cable-knotted, stringer bead and crimped wire wheels are ideal for deburring metal, bead weld prep, cleaning welds, edge blending and more. The precision-balanced wheel and robust construction allows for professional applications.
