Is it safe to use an angle grinder with wood cutting blades?
Bad idea...explained later. But yes, as long as you keep the blade guard on &amp; of course it will "work". Though, it's quite wild compared to a Circular Saw or a smaller Trim Saw. However, "safely" is a bad gamble.

You're talking about multiples of higher RPM's &amp; both accuracy &amp; control will then be largely out the window compared to proper devices. One big problem area is ever so slightly twisting your cut (which is normal &amp; not just common with grinders) &amp; that twist binds to instantly &amp; literally toss the grinder at you or any part of you or anyone else close by.

Grinders usually don't have a braking mechanism &amp; very slowly free-spin down to a stop, you don't want to be the braking mechanism.
