This is a specialty tool for me I think most of you that don't work in guitar pedal shops or anything. However, it does not have to be the most durable product. It only needs to be available when I need to make sure I'm drilling a large hole of the exact size. I'm sure if you tie this to a very powerful tool and drill through metal with it all day you can probably mess it up, but I really don't see any reason why the average Joe would need parts like this to have any more imagination than that is, unless you use them in a particularly long or intense way. I use them to drill holes in metal boxes to install a button for music devices.
