What type of screwdriver and/or drill bit is best to use to change the mount?

A standard Philips screwdriver that's the size for the screws work just fine. FYI DON'T USE THE SCREWS THAT COME WITH THE METAL MOUNT. They will strip. Just reuse the black ones that come are on the lens

Is this for a canon 10-18 lens?

Yes, this is for the Canon EF-S 10-18mm lens. It will give it a EF metal mount. Don't use it with a Full Frame camera though.

Does the lens at 10mm clear the mirror? I wouldn't use it at 10mm but if I zoom wide my mistake, don't want to damage the mirror on my 5D

The mount works on crop sensor cameras. It will not clear the mirror on a full frame camera. It won't even focus on my 5D Mark III but works fine on my 90D.

Will this fit Canon EF-S 18-55mm f/4-5.6 IS STM lens also?

It should but I was trying to use it to mount onto a Canon Mrk 3 D. No success.
