I intend to purchase the socket because it will make my collection of tools more versitle, still need to know the size. I have everything you can imagine in standard, metric, impact, 6 point, 12 point, deep well, torx, allen, even whitworth (for when I get around to collecting RRs!). But my sizes stop at 1 1/4 inch. This includes 1/4, 3/8ths, and half inch, 34 extensions, 6 rachet, 2 torques units, 3/8ths, and 1/2 air drive. Needless to say is I am a tool freak!??
