Dorian Tool 73310122610 Internal Machine Knurler

Product Description

The DORIAN TOOL 73310122610 is an internal machine knurler designed for creating straight knurl patterns on the inside diameter of workpieces. Built for use in CNC and manual lathe applications, this tool accepts a 1/2-inch shank and is engineered to knurl bore diameters starting at 9/16 inches. The overall tool length is 4 inches, with a knurl diameter of 1/2 inch and a face width of 1/4 inch. One knurl wheel is required and is included with the tool. This unit ships as a single piece and is suited for machinists and toolroom professionals working on precision internal features.

Internal machine knurlers are used in machining environments where a textured grip surface is needed on the inside bore of a component. Common applications include threaded inserts, press-fit sleeves, and mechanical parts requiring controlled friction on an internal surface. This tool is appropriate for job shop, production, and toolroom settings where lathe or CNC turning equipment is in use. The 1/4-inch hole diameter accommodates standard knurl wheel mounting configurations.

Installation Notes

Installation and operation of this tool should be performed by a qualified machinist familiar with lathe or CNC turning equipment. Ensure the machine spindle is fully stopped and the tool holder is properly torqued to manufacturer specifications before beginning setup. Confirm workpiece bore clearance is sufficient for the 9/16-inch minimum inside diameter before engaging the knurler. Follow standard shop safety practices including eye protection and chip management procedures.
