The image you posted is a M22520/1-01.
Daniels Manufacturing Corporation sells theirs as an AF8 Standard Adjustable Crimp Tool. They require specific "turrets" that are made for various connector series.
The turrets under the specification are numbered M22520/1-**. I know there are numbers 01 through 17. The Daniels version are also numbered with a THxx part number.
Other OEM manufacturers would be Astro Tool and Balmar. Daniels Manufacturing Corp. is the OEM for many of the connector companies like Deutsch, Amphenol, and VEAM.
The dial on the tool control the depth of the impression of the indentors. The turret controls the positioning of the contact.
