Vargus 80314 Helical Flute Thread Mill 1-12 Internal 4 Flute

Product Description

The VARGUS 80314 is a solid carbide helical flute thread mill designed for cutting internal UN threads to a 1-12 size specification. Built from micrograin solid carbide and coated with TiCN for extended tool life, this mill features 4 right-hand flutes and a cutting diameter of 0.7460 inches. It delivers a length of cut of 2.0420 inches with an overall length of 4.0160 inches. Coolant-through capability supports chip evacuation and thermal management during deep or tight-tolerance threading operations. This tool is intended for use by machinists and toolroom professionals in production and job-shop environments.

The 80314 is suited for internal thread milling applications requiring UN thread form at 12 teeth per inch. It is used in CNC machining centers where helical interpolation is employed to produce precise internal threads in a single tool pass. The right-hand flute direction and TiCN coating make it well-matched for a range of ferrous and non-ferrous workpiece materials. A 3/4 inch shank diameter provides rigid tool holding in standard milling chucks or collet systems.

Key Features

• Micrograin solid carbide construction for rigidity and wear resistance
• TiCN coating extends tool life in abrasive cutting conditions
• Coolant-through design aids chip evacuation and heat control
• 4 right-hand helical flutes for smooth thread form generation
• Cuts internal UN threads at 1-12 (12 TPI) with a 0.7460 inch cutting diameter
• 2.0420 inch length of cut accommodates deeper thread engagement

Compatibility

Designed as an OEM-style replacement thread mill for CNC machining center applications requiring internal UN thread form at 1-12 specification with a 3/4 inch shank interface.

Installation Notes

Installation and use of this tool should be performed by qualified machinists operating CNC machining centers with helical interpolation capability. Ensure the spindle and tool holder are fully powered down and locked out before inserting or removing the tool. Verify shank runout and holder clamping torque per the machine tool manufacturer specifications before cutting. Always confirm programmed interpolation parameters match the thread pitch and cutting diameter of this tool before engaging the workpiece.
