Vargus 80541 Thread Mill 3/8-24 Internal 4 Flute Carbide

Product Description

The VARGUS 80541 is a helical flute thread mill designed for cutting internal 3/8-24 UN threads in solid carbide tooling applications. Built from micrograin solid carbide and coated with TiCN for extended tool life and heat resistance, this four-flute mill produces right-hand internal threads at 24 teeth per inch. With an overall length of 2.9920 inches and a cutting diameter of 0.2910 inches, it is sized for tight-tolerance thread milling on CNC machining centers. Licensed machinists and CNC operators install this tool in precision metalworking and manufacturing environments.

This thread mill is suited for internal thread milling operations on CNC mills and machining centers where a single tool must produce clean, accurate 3/8-24 UN internal threads. It is typically used in aerospace, automotive, and general manufacturing settings where thread quality and tool longevity are critical. The helical flute geometry promotes chip evacuation during cutting. Coolant-through is not supported on this tool, so external coolant or air blast is the standard approach.

Key Features

• Micrograin solid carbide construction for rigidity and wear resistance
• TiCN coating extends tool life and reduces friction at the cutting edge
• Four helical flutes promote efficient chip evacuation during internal thread milling
• Right-hand flute direction for standard CNC thread milling programs
• Cuts 3/8-24 UN internal threads at 24 TPI
• No coolant-through channels - compatible with external coolant or air blast setups

Compatibility

Designed for use in CNC machining centers capable of helical interpolation for internal thread milling operations in the 3/8-24 UN thread standard.

Installation Notes

Installation and operation of this tool is performed by qualified CNC machinists or tooling specialists. Secure the shank in a precision collet or tool holder rated for the shank diameter before use. Verify spindle speed and feed rate settings in the CNC program against the material being threaded before running the tool. External coolant or air blast should be directed at the cutting zone since this tool does not support coolant-through delivery.
