Vargus 80352 Thread Mill M16x2 Internal 4 Flute Solid Carbide

Product Description

The VARGUS 80352 is a helical flute thread mill designed for cutting internal M16x2 ISO metric threads in precision machining applications. Built from micrograin solid carbide and coated with TiCN for extended tool life, this four-flute mill delivers consistent thread geometry in a single helical interpolation pass. The 0.5350-inch cutting diameter and 1.2990-inch length of cut make it well suited for threading operations in rigid CNC machining centers. Coolant-through capability supports chip evacuation and heat control during deep or interrupted thread cuts. At 3.6220 inches overall length, the tool provides sufficient reach for most standard fixturing setups.

This thread mill is used in production and job-shop CNC milling environments where tapping is impractical or where a single tool must serve multiple thread sizes through interpolation. It is appropriate for ferrous and non-ferrous workpiece materials where TiCN coating provides adequate lubricity and wear resistance. Right-hand flute direction suits conventional climb-milling strategies on machining centers running standard G-code helical interpolation cycles. Solid carbide construction minimizes deflection in high-feed finishing passes.

Key Features

• M16x2 ISO internal thread profile for metric fastener applications
• Micrograin solid carbide substrate for rigidity and edge retention
• TiCN coating extends tool life and reduces built-up edge in steel and cast iron
• Four right-hand helical flutes for balanced cutting and smooth chip flow
• Coolant-through design aids chip evacuation in blind and deep-hole threading
• Single-tool helical interpolation eliminates the need for multiple tap sizes

Compatibility

Designed as an OEM-style thread milling tool for CNC machining centers capable of helical interpolation, accepting a 3.6220-inch shank diameter and running ISO M16x2 internal thread programs.

Installation Notes

Installation and use of this tool should be performed by qualified CNC machinists or tooling technicians. Verify spindle collet or toolholder bore matches the 3.6220-inch shank diameter before mounting. Confirm the machining center control supports helical interpolation (G02/G03 with Z-axis feed) before running the threading cycle. Inspect the cutting edges and TiCN coating prior to each use and replace the tool if chipping or coating wear is detected.
