Looking at buying a 4 point square key socket (male) to be used in place of my chuck keys. Does such an item exist ? Where can one fine one ?
Thanks.

Well of course if you have a mill it's easy, you just make one.
But I remember when I didn't have a mill, a 3/8" drive extension was too small and 1/2" drive was too big.
So I used a cheap 1/2" drive extension, layed out the dimensions on the drive that I wanted, roughed it in with a grinder, and then finished it up to final dimension with careful use of a file.

get a sliding t-bar of the appropriate size and cut of the bar or look for a reducer say 3/4 to 1/2 or 1/2 to 3/8, can be found in socket sets.
But easier on the mill

What size of square bar will fit into the hole in the chuck? Maybe you can find a piece of suare section key steel taht's a nice fit. Then, take the square key to a tool supplier, find a 12 point socket that fits (or can be persuaded to fit).

Loctite or epoxy the key in the socket, job done.

Put 2 sockets together with a short piece of hex stock. The socket that is on backwards will have the square hole facing out.

"Put 2 sockets together with a short piece of hex stock. The socket that is on backwards will have the square hole facing out."

But then you will be "offering up" a "female-to-a-female" won't you?

What am I missing?

TR, What advantage do you expect to gain over your standard chuck keys? I'm just curious.

I would assume he wants more torque. In a few months you will see a broken or worn out chuck on E-bay. And he will need a new size "socket" to fit his new chuck.

Amazingly, even chuck keys get lost or broken. Also, truing in a 4-jaw chuck can be much more quickly and conveniently done if you have two keys and use them on opposite sides. Maybe he wants a #2?

May I suggest the use of calipers to measure the ID of the "socket" hole....and make one to fit..

Sears Craftsman has THESE (http://www.sears.com/shc/s/s_10153_12605_Tools_Auto+%26+Mechanics+Tools_Socke ts?filter=Socket+Depth%7CStandard%5EContact+Points %7C8+point&viewItems=24&sbv=Craftsman&sbf=Brand) 8 point sockets available for square drive heads. You would still need to make the square piece to fit your chuck.

I use a automobile cross type lug wrench with the sockets removed and the four ends ground to square. One tool to fit the D1-3 spindle and chucks.

I missed something. I thought the OP was talking about a chuck key. All my chucks have square female recessed drives for the pinion and my keys are male square drives.

I have a set of Male square sockets for pipe plugs.
1/16" increments from 1/4" up to 3/4". Larger are available.
Available from your Snapon or Mac tool dealer.

I made 2 keys to fit my 4 jaw because the one that came with it was junk and I wanted the 2-key option for centering.

New keys:

Original key:
It's funny about this Chinese stuff. The chuck seems well made and well finished but the key looks like an afterthought. Obviously the chuck has shortcomings but it's head and shoulders above the key.

Closeup of the square end that measures .260 across flats, the new ones fit nicely at .280. It's in the bin now, not sure what it'll be used for.

I got the same problem with my lathe.. I got 2 or 3 chuck keys of verious lengths with it, All have that lame flat knurled center on the bar.. And all allow the bar to slip right outta the shaft. Tempting to locktite it or something...

Sound like a good idea. I will have to give it try - after I make another key.

Although the OP specified he wanted a male 'socket' to fit his chuck. I have seen chucks with male adjusters and matching female keys. I seem to recall that they were fairly large old 4 jaw chucks.

Ok, a quick Google search for Pipe Plug Sockets returned these SK Pipe Plug Sockets (http://www.mytoolstore.com/sk/sk03221.html).

Until I read the response from terry_g, I had never heard of them.
