Vargus 80295 Helical Flute Thread Mill 7/16-28 Internal

Product Description

The VARGUS 80295 is a solid carbide helical flute thread mill designed for cutting internal UN threads at 7/16-28 (28 TPI). The tool features a right-hand flute direction, three flutes, and a TiCN coating applied over a micrograin carbide substrate. With an overall length of 2.8740 inches and a cutting diameter of 0.3710 inches, the 80295 is built for precision thread milling in CNC machining centers where dimensional accuracy and tool life are critical. Coolant-through capability supports chip evacuation and heat management during operation.

This thread mill is suited for internal thread milling operations in production and job-shop environments where a single tool must generate clean, accurate 7/16-28 UN threads. The helical flute geometry and TiCN finish make it appropriate for harder workpiece materials where tool wear is a concern. It is typically deployed by machinists and CNC programmers working in aerospace, automotive, medical device, and general precision machining applications.

Key Features

• Solid micrograin carbide construction for rigidity and wear resistance
• TiCN coating extends tool life in difficult-to-machine materials
• Three right-hand helical flutes for smooth cutting action and chip clearance
• Coolant-through design supports chip evacuation and thermal control
• Cuts internal 7/16-28 UN threads in a single helical interpolation pass
• 0.8750-inch length of cut accommodates typical thread depth requirements for this thread size

Compatibility

Designed for use in CNC machining centers capable of helical interpolation; compatible with applications requiring internal UN thread form at 7/16-28, 28 TPI.

Installation Notes

Thread mills require a CNC control capable of helical interpolation. The tool should be held in a precision collet or shrink-fit holder appropriate for the shank diameter to minimize runout. Verify spindle speed, feed rate, and coolant flow settings in the CAM program before cutting. Do not use in manual milling machines or on controls that lack circular interpolation capability.
