Grinders with X-LOCK fastening system

X-LOCK fastening system

— an advanced attachment system used on some angle grinders (see "Type"), predominantly manufactured by Bosch and Makita.

This system is somewhat more expensive than the traditional 22mm nut or washer mount, but has a number of advantages over it. Firstly, X-LOCK provides the easiest and fastest installation: no need to fiddle with additional parts or tools, just put the disc on the spindle and press it until it clicks; in turn, to remove the working nozzle, just press the button that turns off the latch. Secondly, you can install the nozzle with only one, correct side to the tool — the mounting design will not allow otherwise. The main disadvantage of machines with this system is incompatibility with cheaper and more common discs for a standard 22 mm mount; and equipment for X-LOCK is not yet available in every hardware store.
