the angle grinder is one tool I don't let my son touch.
I've seen more serious bodily damage done by those stupid little things than any other tool I know of.
It may always be related to user error and letting one's guard down - but that's the problem, it's so easy to do that when using one.
In fact - that reminds me - I've got an old Milwaukee that has a little flip tab lockout to protect the on button from being pressed accidentally.
A friend of mine just bought a newer version of mine - and instead of the tab, it's got a button that protects it - but ALSO works like a lock to hold it powered ON.
Am I crazy in thinking that's the worst feature EVER for an angle grinder???
Or is that common on them? I've had mine for so long I can't remember how others have worked.
(maybe his is broken?)
I won't touch the thing. I like mine where you just loosen your grip and it's off. Even THAT isn't always quick enough.
