Review on Bosch EX1006 Straight Shank Extension by Ian Bates

As an electrician I was hoping for this extension, I can say that as an electrician the standard drill bit size is 7/8. So if the head of this extension is 7/8 then the purpose of the extension will be defeated if the head of the extension barely goes through the hole. In my opinion this is a big mistake in planning this expansion so yes it will bear fruit but I really wonder how long it will take. In theory, if you just made a 12 inch auger, they would sell like hotcakes.
