Die Grinder with chuck instead collet

[bushwhaker]

Came across this two die grinders in bay.

First one with collet, but other have keyed chuck.
Is not it a dangerous use bits wit 28 000 rpm? Never got something like that.

Bits? I assume you mean drill bits? You wouldn't normally use drill bits in a die grinder.

I don't see why, any bit that is dangerous in a chuck will be dangerous in a collet.

I have a collet die grinder but also modified a chuck to fit it so I can use small dremel type bits or non standard size bits (the collets are only 1/4 and 1/8)
