The Sperzels come with a template for locating the hole you have to drill.
You use the sleeve nut in the tuner hole to locate the template - then you mark or center punch the hole location.
Get the proper sized bit, tape it off to mark the depth you want to go (don't have to go very deep) and carefully drill.
It's a 5 minute job. But if you're just really nervous about using a drill on your guitar, I suppose I can understand that.
