I've looked unsuccessfully at all the stores for years for longer drill bits. Sometimes you just need them. I ended up buying single/expensive ones over the years as I needed them. When I placed my firstc Grizzly order for some machine spare parts I saw this set of long bits in their catalog. The price was fantastic and because of the other items I bought, Grizzly didn't charge me any more for shipping of these bits. I couldn't be happier. This product is highly recommended for DIY and light-duty usage. The small ones look they will be easy to break but at this price, I'll just get another set eventually.
