Where would one get a good Robertson bit? I get mine from McFeeleys and
Kreg.

I buy my driver bits in bulk from Lee Valley Tools. But, I use
magnetic type bits not the shanked ones. (Except for some I bought for
the Yankee Screwdriver clone I bought from them.) I don't know if LV
sells the shanked ones or not. I suspect they do.
