Vargus 80292 Helical Flute Thread Mill 12-32 Internal

Product Description

The VARGUS 80292 is a solid carbide helical flute thread mill designed for cutting internal 12-32 UN threads. It features three right-hand flutes and a TiCN coating, making it well suited for high-wear applications where tool life and surface finish consistency matter. The cutting diameter is 0.1730 inches with a length of cut of 0.4530 inches and an overall length of 2.2440 inches. The micrograin carbide substrate supports sharp edge retention at elevated feeds. Coolant-through capability helps evacuate chips and manage heat during deep or tight-tolerance thread milling operations. Licensed machinists and CNC toolroom technicians are the primary installers of this tool.

This thread mill is intended for internal thread milling of 12-32 UN threads in machining center applications. It is a strong fit for shops working with small-diameter threaded features in ferrous and non-ferrous workpiece materials where a single tool must produce a finished thread in a helical interpolation cycle. The right-hand flute direction and TiCN finish make it practical for use in steel, stainless, and similar materials at appropriate surface speeds.

Key Features

• Solid micrograin carbide construction for edge retention and rigidity in small-diameter thread milling
• TiCN coating reduces friction and improves wear resistance in ferrous and stainless applications
• Three right-hand helical flutes for balanced cutting action and smooth chip flow
• Coolant-through design supports chip evacuation in blind-hole and deep-thread applications
• 12-32 UN internal thread form at 32 teeth per inch
• Cutting diameter of 0.1730 inches with a 0.4530-inch length of cut

Compatibility

Designed for CNC machining centers capable of helical interpolation; suited for cutting internal 12-32 UN threads in applications requiring a solid carbide helical flute thread mill with a 0.1730-inch cutting diameter.

Installation Notes

Thread mills of this type are installed and run by CNC machinists using standard tool holders appropriate for the shank diameter. Confirm runout and tool holder clamping before commencing a thread milling cycle. Coolant-through capability should be connected to the machine spindle coolant supply for best chip evacuation results. Follow the toolpath programmer's recommended helical interpolation parameters and do not exceed the tool manufacturer's specified cutting data for the workpiece material.
