Vargus 80248 Thread Mill 7/16-14 3 Flute Solid Carbide

Product Description

The VARGUS 80248 is a straight-flute internal thread mill designed to produce 7/16-14 UN threads in a single helical pass. Built from micrograin solid carbide, the tool offers rigidity and wear resistance suited to production milling of internal threads in ferrous and non-ferrous workpieces. The 3/8-inch shank mounts directly in standard ER or milling collet chucks. A TiCN coating reduces friction and extends tool life in demanding materials. With 3 flutes and 14 teeth per inch, the 80248 generates clean thread forms at the 0.354-inch cutting diameter across a 0.214-inch length of cut. Machinists and CNC programmers working in job shops, aerospace, or general manufacturing will find this tool a direct-fit solution for UN internal threading applications.

The 80248 is suited for CNC machining centers executing circular interpolation thread-milling cycles on internal UN thread forms. It is appropriate for through-hole and blind-hole applications where a single-point tap presents chatter or breakage risk. The straight-flute geometry makes it practical in both climb and conventional milling directions. At 2.874 inches overall length, the tool reaches moderate-depth features without excessive overhang. It is used in precision manufacturing environments where thread quality and tool longevity are priorities.

Key Features

• Micrograin solid carbide construction for rigidity and extended edge life
• TiCN coating reduces heat buildup and tool wear in hard and abrasive materials
• 3 straight flutes with 0.354-inch cutting diameter and 0.214-inch length of cut
• 3/8-inch shank diameter fits standard ER collet and milling chuck systems
• 2.874-inch overall length accommodates moderate feature depths

Compatibility

Designed as an OEM-style thread mill for CNC machining centers capable of circular interpolation thread-milling cycles producing 7/16-14 UN internal threads.

Installation Notes

Installation is performed by qualified CNC machinists or tooling technicians. The tool should be seated in a properly sized ER collet or milling chuck and torqued to the chuck manufacturer's specification before use. Verify spindle direction, feed rate, and helical interpolation pitch in the CAM program or G-code before cutting. Coolant-through is not supported; use external coolant or mist where applicable.
