Bosch metal-cutting and grinding abrasive wheels with the X-Lock mount feature a wheel change that’s three times faster than conventional interfaces, the company says. X-Lock wheels are ejected with a lever pull and firmly connected without the need for a spanner wrench or flange nuts. An audible snap tells the user that the wheel is installed securely on the tool. The X-Lock accessories are designed to provide faster change-out for grinders with X-Lock mounts, and most are backward compatible with standard 7/8″ mounts. High-quality wheels are designed to cover core grinding applications including but not limited to bonded discs, flap discs, wire wheels, and diamond blades.
