This is a nice starter set of accessories that will bring a lot of flexibility to your tasks. Instead of just driving nails and staples, you will be able to do tasks ranging from shop clean-up to filling tires and mattresses. This versatile tool kit has all that you need to inflate rafts, balls and tires. Light weight aluminum with solid steel construction makes it a convenient combination of durability and ease of use. As good as Porter Cable P17ACK but at a much lower price.
