Portomatic #500 keyless chuck
« on: January 24, 2020, 09:54:25 PM »
I am at a loose for the JT size for this chuck, it measures .652 at the top of the female taper I don't know what the bottom measurement is I have no way to measure this.
I"m looking at a #6JT but the measurement for this is .6760.
Any help much appreciated.
