I’m looking to drill holes in my TE for a 24mm button and a Neutrik jack, and I’ve found the hole saw I need, but then i came across something called a shank mandrel. Is a mandrel necessary for using a hole saw? Can i attatch either of these to an electric screwdriver or do I need a power drill?
EDIT: My TE is gutted and I plan on using an MC Cthulhu until the PS360’s come back in stock. This is my first time doing any kind of modding outside of button swapping.
