Allen key to mount in drill

Jan 19, 2018 6 Replies

I'm looking for what is effectively an allen key that's been sawn off so it can be put into a drill chuck but I can't seem to find any online as I'm not sure what these are called, can anyone please advise me on what terms to search with


Hex bits? Normally 1/4in drive, and a set comes with an adaptor which fits the drill chuck. You then fit the size you need to that - just like screwdriver bits.

You'll find sets in any decent tool shop, or Ebay.

I wanted something similar - but in particular wanted long reach bits with a ball end (so you can drive them off axis). In the end I picked up a cheap set of keys like:

With the intention of chopping the short bit off with an angle grinder... as it turned out there were actually far better quality than I was expecting, so I kept them as a set! I will get a second set to convert for drill use.

They look exactly like the lidl ones a few weeks ago, £5 IIRC. I only bought one set.
