This is a super handy tool to have in your garage or car. Nice knurled aluminum knob that you can turn even when oily and greasy! Magnetic and will hold all standard 1/4 inch bits. Comes with no. 1 and 2 phillips bits, 2 straight screw driver bits and six torx (star) bits. You will love this tool when working in tights spaces (ie - getting your front dash or rear speaker cover off!)
