This is a free standing rod hone .
You will need what's called mandrel .
Which style I do not know .
Sized according to what your honing .
1" for one inch bore 2 for two etc .
I'm sure there is some overlap in sizing .
AN-600 honing head for most cylinders. Stones are a personal choice.
I have multiple ones for rods (big and small end) as well as carb bores. Just order the diameter and length you want.
