[Shop-talk] 1/2 socket drive adapter for power auger?

Excuse the metrication, comes with being the other side of the Pond.

Just been out to the shop to look at a set of impact sockets, metric not 
imperial, and I wonder if you could make up a 7/8 inch bore sleeve to 
take the socket or a 1/2 square adapter. 7/8 inch equals 22.225mm. My 
13mm socket (pretty close to 1/2 inch) is 24mm o.d. and a 1/2 inch 
extension bar is 22.1mm o.d.

I have a feeling tool dimensions are pretty similar worldwide so it 
could be worth your while checking some measurements. Looking at the 
Snapon catalogue I see that a 1/2 inch thin wall impact socket has an 
o.d. of 7/8 inch so should fit ok. You would have to drill and pin the 
socket or extension with a 1/4 inch ht bolt or similar.

Cheapest way round the problem I can see. Maybe not the Snapon component 
but possibly some research will turn up a cheaper alternative. The thin 
wall aspect makes the difference.

Good luck.

Rather than buy a corded impact wrench that I will likely never use again, a friend has offered to loan me his Harbor Freight power auger he bought for post hole digging. It has a 7/8" round shaft with a pin through it that drives the auger. I'd like to adapt that to the impact socket but I can't find an adapter. Am I Googling wrong or is that something that likely doesn't exist?
