Bull. Diamond wheel on an angle grinder is the wrong combination,
but not for that reason. Kickback has nothing to do with the wheel
on the grinder,

****wit.

Potty mouth.


A diamond disc will not cut wood due to the mimimal depth of the
cutting surfaces, it will instead burn through whilst spinning at
circa 10,000 RPM.

Don't use many angle grinders do you? Regardless of the 10,000 RPM, it
still does not approach the speed of a simple circular saw or a sawzall.


This is exactly how someone killed themselves with a diamond disc in
an angle grinder, it kicked back off a tree stump and embedded itself
in their neck severing an artery. Most likely a tabbed diamond disc
where the slots snagged on a particularly resilient group of wood
fibres so launching the grinder up into the victim's neck.

It's clear you don't use an angle grinder much. Any wheel in an angle
grinder is capable of kick back. All you have to do is contact the leading
edge of the rotating wheel. To my point - it's not a matter of the wheel in
use, it's a matter of where you contact it.
