Vargus 80301 Internal Thread Mill 3 Flute Solid Carbide

Product Description

The VARGUS 80301 is a solid carbide, helical flute thread mill designed for cutting internal threads in a variety of workpiece materials. With three right-hand flutes, a 0.1920-inch cutting diameter, and a 0.5250-inch length of cut, this tool generates UNC, UNF, and UNEF thread forms in a single helical interpolation pass. The bright, uncoated finish keeps the tool ready for use as received or compatible with post-treatment applications. Coolant-through capability supports chip evacuation and heat management during threading operations, extending tool life in production environments.

This thread mill is suited for machining centers and CNC milling machines capable of helical interpolation. It is used in job shops, production machining, and toolroom applications where a 1/4-inch shank and 20 TPI specification are required. The 2.2440-inch overall length provides adequate reach for standard internal threading setups. Machinists working with tapped holes in ferrous and non-ferrous materials will find this tool appropriate for thread forms ranging from fine to extra-fine pitch on the UNF and UNEF standards, as well as standard UNC applications.

Key Features

• Solid carbide construction for rigidity and wear resistance in threading applications
• Three right-hand helical flutes for efficient chip removal during internal thread milling
• Coolant-through design aids chip evacuation and thermal control at the cutting zone
• Compatible with UNC, UNF, and UNEF thread standards in a single tool
• Bright, uncoated finish suitable for use as received or post-coating processes
• 1/4-inch shank diameter fits standard collet and toolholder systems on CNC machines

Compatibility

Designed for use on CNC machining centers capable of helical interpolation with a standard 1/4-inch shank toolholder or collet system; thread standards supported are UNC, UNF, and UNEF at 20 teeth per inch.

Installation Notes

This tool is installed by a machinist or CNC setup technician into a compatible 1/4-inch collet or toolholder on a CNC milling machine programmed for helical interpolation. Ensure the spindle is fully stopped and the machine is in a safe state before toolholder changes. Verify runout within acceptable tolerance after installation to prevent premature wear or thread form error. Coolant-through connections should be confirmed active before production threading begins.
