The hole is 5/16" square. You can use a brazed carbide tool bit with a 60 degree point. You probably need to shorten the shank.

I've used the Model C a number of times and wondering how you would set up to put a radius on the end of a 1/4 inch rod. Problem always is that you can't get the radius attachment close to the chuck. The rod has to hang out about 3 inches. Steady rest is not an option because the radius attachment is in the way. Are you supposed to take 0.001 cuts or what?

OK I should have said collet, bad enough, you are right with the chuck it would be totally hopeless.

That agrees with my experience. I found the shims to be a hassle. I used 3/8 square HSS tool blanks and took them down to 5/16 x 3/8 on a surface grinder. The top of the 3/8 high tool blank is in about the right spot, easy enough to grind down a little if needed. I wonder why Hardinge didn't use a 3/8 sq hole in the first place, maybe they had trouble with the part cracking and narrowed it up to 5/16 to resolve that.
