Vargus 80315 Thread Mill 5/8-11 Internal 4 Flute Carbide

Product Description

The VARGUS 80315 is a helical flute thread mill designed for cutting internal 5/8-11 UN threads in a single helical interpolation pass. Built from micrograin solid carbide and coated with TiCN, this tool delivers extended tool life and resistance to wear in ferrous and non-ferrous workpiece materials. It runs 4 right-hand flutes with 11 teeth per inch and features through-coolant capability, making it well suited for deep or blind-hole threading operations where chip evacuation and heat management are critical. Machinists and CNC operators in production and job-shop environments are the primary users of this tool.

This thread mill is intended for internal threading applications on CNC machining centers using helical interpolation. It produces 5/8-11 UN threads to standard inch thread specifications. The through-coolant design supports consistent performance in harder materials and in setups where flood coolant alone is insufficient for chip removal. It is appropriate for both prototype and production threading work where solid carbide tooling is specified.

Key Features

• Cuts internal 5/8-11 UN threads in a single helical pass
• Micrograin solid carbide substrate for rigidity and edge retention
• TiCN coating for wear resistance and extended tool life
• 4 right-hand helical flutes with 11 teeth per inch
• Through-coolant capability for chip evacuation in deep or blind holes
• Overall length of 3.6220 inches accommodates standard toolholder setups

Compatibility

Designed for use on CNC machining centers capable of helical interpolation, producing internal 5/8-11 UN threads per standard inch thread specifications.

Installation Notes

This tool is installed by a machinist or CNC setup technician into a compatible toolholder sized for the 3.6220-inch shank diameter. Confirm spindle direction and interpolation path are programmed for right-hand thread cutting before running. Through-coolant should be activated prior to the cutting pass to maintain chip flow and thermal control. Inspect the cutting edges before use and replace the tool at first sign of edge wear to avoid thread-form error.
