Dorian Tool 73310122620 Internal Machine Knurler

Product Description

The DORIAN TOOL 73310122620 is an internal machine knurler designed for creating precise knurled patterns on the interior surfaces of workpieces. It features a 1-1/8 inch inside diameter and a 3/4 inch shank diameter, making it suitable for CNC lathes and manual engine lathes where internal knurling is required. The tool is 6 inches long with a 1 inch knurl diameter and a 3/8 inch face width. One knurl wheel is required and is included with the tool. The knurl wheel produces a straight pattern. This tool is intended for use by machinists and toolroom professionals working with metal or similar materials.

The 73310122620 internal machine knurler is used in machine shop environments where interior bore surfaces require a knurled finish for grip, press-fit retention, or cosmetic requirements. It mounts via a 3/4 inch shank into a standard toolholder on a lathe or turning center. The 1/2 inch hole diameter accommodates the knurl wheel mounting pin. This tool is suited for both production runs and one-off toolroom applications.
