Vargus 80565 Thread Mill 1-11-1/2 Npt 4 Flute Solid Carbide

Product Description

The VARGUS 80565 is a helical flute thread mill designed for cutting 1-11-1/2 NPT threads in both internal and external configurations. Built from micrograin solid carbide and finished with a TiCN coating, this tool is engineered for precision threading in tough materials. It runs a 4-flute, right-hand flute geometry with a cutting diameter of 0.6210 inches and a length of cut of 1.1310 inches. The 5/8-inch shank diameter and 4.0160-inch overall length make it compatible with standard milling setups. Machinists and pipe fitting fabricators working in metalworking and industrial environments will find this tool suited to demanding NPT thread milling applications.

This thread mill is built for NPT (National Pipe Taper) thread applications, handling both internal and external thread forms in a single tool. It is appropriate for use in machining centers performing pipe fitting, fluid system, and industrial assembly work where NPT thread forms are required. The minimum nominal diameter rating of 1.0000 inch establishes the smallest bore it is intended to thread. No coolant-through capability is present, so external coolant delivery should be planned accordingly in high-heat applications.

Key Features

• Cuts 1-11-1/2 NPT threads internally and externally with one tool
• Micrograin solid carbide construction for rigidity and wear resistance
• TiCN coating extends tool life in abrasive and ferrous materials
• 4-flute, right-hand helical geometry for efficient chip evacuation
• 0.6210-inch cutting diameter with 1.1310-inch length of cut
• No coolant-through design - external coolant delivery required

Compatibility

Designed for use in CNC machining centers capable of helical interpolation; suitable for cutting 1-11-1/2 NPT thread forms with a minimum nominal diameter of 1.0000 inch in internal or external configurations.

Installation Notes

Thread milling with helical interpolation requires a CNC machining center with three-axis simultaneous movement capability. Confirm spindle toolholding is rated for the 5/8-inch shank diameter and that runout is within acceptable tolerance before starting a cut. Power down and lock out the machine before installing or removing the tool. External coolant should be directed at the cutting zone throughout the operation since this tool does not support coolant-through delivery.
