This is the kind I have. You can’t fit it in a drill.

It came with no instructions.

This is driven by a square that goes in the end and is attached to a power drill. It is basically diy useless stuff.
It doesn’t have the strength and power to do much at all.

There’s no square in the end, just a very small philips screw. No mention of use with a drill. I think you’re just supposed to jiggle it around with the handle, which I’ve been doing.

Anyway I’ll finish this container of crystals, run some cold water down it, then have a shower and see what happens.
