Vargus 80329 Thread Mill 1/8-27 Nptf 3 Flute Ticn Carbide

Product Description

The VARGUS 80329 is a helical flute thread mill designed for cutting 1/8-27 NPTF threads in both internal and external applications. Manufactured from micrograin solid carbide and finished with a TiCN coating, this tool offers high wear resistance and extended tool life in demanding threading operations. It features 3 right-hand flutes with a 0.3010-inch cutting diameter and a 0.3890-inch length of cut. Coolant-through capability supports chip evacuation and heat control during the threading cycle. With a 2.4020-inch overall length and matching shank diameter, the tool fits standard toolholders used in CNC machining centers.

This thread mill is suited for machining NPTF pipe threads in ferrous and non-ferrous materials where a single tool must handle both internal and external thread profiles. Typical applications include hydraulic fittings, pneumatic manifolds, and fluid-system components requiring leak-free tapered pipe thread connections. It is installed and operated by machinists and CNC programmers in job shop, production, and maintenance machining environments. The helical flute geometry and TiCN coating make it a practical choice for threading stainless steel, alloy steel, and hardened materials where tool longevity matters.

Key Features

• Cuts 1/8-27 NPTF threads to tapered pipe thread standard - no separate internal and external tools required
• Micrograin solid carbide substrate provides rigidity and edge integrity in difficult-to-machine materials
• TiCN coating reduces friction and improves wear resistance compared to uncoated carbide
• Coolant-through design supports chip clearance and thermal management at the cutting edge
• 3 right-hand helical flutes at 27 TPI with a 0.3010-inch cutting diameter and 0.3890-inch length of cut
• 2.4020-inch overall length with matching shank diameter for straightforward toolholder setup

Compatibility

Designed for use in CNC machining centers capable of helical interpolation; compatible with standard toolholders accepting a 2.4020-inch shank diameter. Thread standard is NPTF at 1/8-27 thread size.

Installation Notes

This tool requires a CNC machining center programmed for helical interpolation - it cannot be used in a conventional tapping cycle. Confirm toolholder runout is within acceptable limits before beginning the threading operation, as excess runout will degrade thread quality and shorten tool life. Follow the machine manufacturer and toolholder torque guidelines when securing the shank. Enable coolant-through flow before initiating the cut to maintain proper chip evacuation.
