Vargus 80044 Thread Mill 3/8-16 Internal Solid Carbide

Product Description

The VARGUS 80044 is a straight flute thread mill designed for cutting internal 3/8-16 UN threads in a single helical pass. Built from micrograin solid carbide and coated with TiAlN for heat and wear resistance, this tool is suited for high-speed threading operations in ferrous and non-ferrous materials. It carries a 1/4 inch shank diameter, a cutting diameter of 0.236 inches, and a length of cut of 0.562 inches. With 3 flutes and 16 teeth per inch, it produces clean, accurate thread forms with reduced vibration. Machinists and CNC operators in production and job shop environments rely on this geometry for consistent internal thread quality.

This thread mill is used for internal 3/8-16 UN threading in CNC machining centers capable of helical interpolation. Typical applications include threading operations in tool steel, stainless, aluminum, and cast iron where tap breakage is a concern or where a single tool must serve multiple thread sizes in the same diameter range. Its compact 2.244 inch overall length suits standard tool holders in vertical and horizontal machining centers. No coolant-through capability is present, so external coolant or minimum quantity lubrication is the standard approach for chip evacuation.

Key Features

• Micrograin solid carbide substrate for superior edge retention and rigidity
• TiAlN coating extends tool life in elevated-temperature cutting conditions
• 3 straight flutes with 16 teeth per inch for smooth internal thread formation
• Cuts 3/8-16 UN internal threads via CNC helical interpolation
• 1/4 inch shank diameter fits standard ER and precision collet chuck systems
• No coolant-through design - compatible with external flood or MQL delivery

Compatibility

Designed as an OEM-style thread milling tool for CNC machining centers capable of helical interpolation and programmed for 3/8-16 UN internal thread profiles.

Installation Notes

Installation and operation of this thread mill is performed by qualified CNC machinists or tooling engineers. Secure the 1/4 inch shank in a precision collet or milling chuck and verify runout before cutting. Program the machining center for helical interpolation at the correct pitch and thread depth per the workpiece drawing. Always confirm spindle speed and feed rate are appropriate for the workpiece material before engaging the cut.
