Vargus 80216 Thread Mill 2-56 3-56 Internal Solid Carbide

Product Description

The VARGUS 80216 is a straight flute thread mill designed for cutting internal threads in the 2-56 and 3-56 size range. Built from solid carbide, it delivers the rigidity and wear resistance required for precision thread milling in ferrous and non-ferrous materials. The tool features 3 flutes, a 1/4 inch shank diameter, a cutting diameter of 0.065 inches, and an overall length of 2.244 inches. With a bright, uncoated finish and 56 teeth per inch, this thread mill is suited for shops and machinists producing small-diameter internal threads to UNC and UNF standards.

The 80216 is used in CNC machining centers for internal thread milling operations requiring fine-pitch, small-diameter thread forms. Its 0.197 inch length of cut accommodates shallow to moderate thread depths in the 2-56 and 3-56 ranges. This tool is appropriate for production environments and job shops where thread milling is preferred over tapping for improved thread quality, tool life, or access in blind-hole applications.

Key Features

• Solid carbide construction for rigidity and extended tool life in thread milling applications
• Cuts internal threads in 2-56 and 3-56 sizes to UNC and UNF thread standards
• 3 straight flutes with 56 teeth per inch for consistent thread form generation
• 1/4 inch shank diameter for compatibility with standard collet and toolholder systems
• Bright, uncoated finish suitable for use with cutting fluids across a range of workpiece materials
• No coolant-through design; external coolant or flood coolant recommended during operation

Compatibility

Designed for use in CNC machining centers capable of helical interpolation, with toolholders accepting a 1/4 inch shank. Suitable for producing internal UNC and UNF threads in the 2-56 and 3-56 size range.

Installation Notes

Thread milling with this tool requires a CNC machine with helical interpolation capability. Secure the 1/4 inch shank in a precision collet or toolholder to minimize runout before operation. Ensure the workpiece is rigidly fixtured and apply appropriate external cutting fluid, as this tool does not include coolant-through capability. Follow machine tool manufacturer guidelines and applicable shop safety procedures when setting up and running thread milling cycles.
