Here a few photos

The Armstrong tool holders are 3/4" to 7/8" for small lathes you can mill down to fit a Aloris AXA 1/2" tool bit holder. Now you can adjust the Armstrong tool holders and not need the American tool

Aloris use to make a holder for threading back 1970's. But most use carbide today or just sharpen HSS tool bits. Dave

The ABEC rating mostly refers to tiny differences in runout, with higher numbers being microscopically more precise & astronomically pricier. <

20 bucks gets ya a 4" digital at Harbor Freight a couple bucks more gets ya the 6"
