This is a nice set of standard and specialty driver bits. It includes not only standard bits but security bits as well. It also includes several #2 Philips bits (the ones that strip out the most and are the most common Philips). Also included are 1/4" socket adapter, magnetic bit extension, 1/4" socket, and a molded clamshell storage case. Purchased individually, these bits would cost over $100 at our local hardware store, for $12 this is a very good deal! The set will come in very handy around the house and we are very happy with the purchase.
