This kit provides all of the necessary bits one would need to install or remove any type of screw head. They are perfect for quick change, especially the driver. Great price too.
This is a product I was wanting to get for myself all through the previous Christmas Season but couldn't justify at the time. It finally went back on sale at $19.99. When I first looked in the seeing the drill bits and the speedlock connector my first thought was "cheap". The black oxide bits at least looked like they'd last. Then I looked closer, and I quickly noticed there were doubles (or more) of every bit. So I counted. There are 16 of the 1 inch P2 bit. There are a total of 54 different pieces, less if you don't count the 2 inch bits, because they are same sizes as 1 inch. I gave this two stars solely because of the speed lock quick connector, while cheap feeling does work, which is why I bought this set over 100-PC Accessory Kit (00931639000P ). If you don't want the speed lock get the other set, it's usually on sale at $15 and does have the same magnetic bit holder. Also NO part of either set counts towards the Craftsman Lifetime Warranty.
