Klein Tools 66070 – Frequently Asked Questions

1) What socket sizes come in the Klein 66070 flip impact socket set?
Five flip sockets cover ten sizes: 3/8 x 7/16 inch, 1/2 x 9/16 inch, 5/8 x 11/16 inch, 3/4 x 13/16 inch, and 7/8 x 15/16 inch. Each socket is double-ended, so you flip it on the adapter instead of carrying a second socket. That range covers the common nut and lag sizes on panel mounting, strut and conduit support hardware, and pole line hardware.
2) Will the Klein 66070 sockets work on my 1/2-inch drive impact wrench, or only on a 1/4-inch hex impact driver?
Both. The set ships with two nested adapters covering 1/4 inch hex and 1/2 inch square drive, so the same five sockets run off a cordless hex impact driver or a 1/2 inch drive impact wrench. Pick the adapter that matches the tool in your hand, seat the socket on it, and go.
3) Are the Klein 66070 sockets actually impact rated, or are they chrome hand sockets?
Impact rated, made from 4140 steel rather than the chrome alloy used on hand sockets. 4140 is a chrome-moly grade that takes the shock loading from an impact driver or impact wrench instead of cracking. Don't substitute chrome hand sockets on an impact tool.
4) Why does this Klein set say 7 pieces when there are 10 socket sizes?
The seven pieces are five double-ended flip sockets plus two nested drive adapters. Because each socket carries a different size on each end, five sockets give you ten sizes. The carrying case comes with it and isn't counted in the piece total.
5) Are these Klein flip sockets 6-point or 12-point?
6-point. The six-point opening puts the drive faces flat against the flats of the nut, which is what you want under impact because it reduces slipping and rounding on square-shouldered and already worn fasteners. If you need to catch a fastener at 30-degree increments, a 12-point is the wrong call here since these are 6-point only.
6) Will the socket fall off the adapter when I'm working overhead on a bucket or a tower?
The adapter and socket use a cross hole design that locks them together and keeps them from separating unintentionally during high-impact work. That matters on tower and pole hardware where a dropped socket is a lost socket at best. The socket still pulls off by hand when you want to flip it to the other size.
7) What is the Klein part number to order this flip impact socket set?
Klein Tools model 66070, the 7-piece flip impact socket set. That single number covers the five sockets, both adapters, and the case.
8) How much does the Klein flip impact socket set weigh and how big is the case for a truck drawer?
The full kit in its case runs 2.9 lb (1.3 kg) and measures 8.25 inches long, 4.9 inches wide, and 2.8 inches high. That footprint drops into a van drawer or the bottom of a tool bag without taking the space a 10-socket tray would.
9) How do the crews tell the sizes apart quickly with the Klein 66070 set?
The sockets are color coded, so on a dark panel room floor or up in a bucket you pick by color instead of reading stamped numbers. For a fleet or MRO crib, that's the practical argument for this set: one small case, ten sizes, and less time hunting for the right socket.
10) Does the Klein 66070 set include a case, or do I need to buy storage separately?
A carrying case is included along with the five sockets and two adapters. Nothing else is needed to store or transport the set. You do need to supply your own impact driver or impact wrench, since no drive tool comes with it.
