Osg 4120000913 Thread Mill 6-32 Unc 3 Flute Solid Carbide

Product Description

The OSG 4120000913 is a solid carbide helical flute thread mill designed for cutting internal 6-32 UNC threads in a single helical interpolation pass. With a cutting diameter of 0.103 inches and a length of cut of 0.094 inches, this tool handles tight-tolerance internal threading in ferrous and non-ferrous materials. The WXS coating provides added wear resistance and heat reduction at the cutting edge. A 0.25-inch shank diameter and 1.661-inch overall length make it compatible with standard CNC machining center toolholders. This tool is installed and run by machinists and CNC operators working in precision manufacturing, job shop, and production environments.

This thread mill is suited for internal 6-32 UNC threading operations in CNC machining centers with helical interpolation capability. The right-hand flute direction and right-hand thread direction follow standard UNC conventions. With 3 flutes and 32 teeth per inch, it produces a clean thread form in a single programmed pass, making it a practical choice for low-volume and high-volume production runs where thread quality and tool life are critical.

Key Features

• Solid carbide construction for rigidity and wear resistance in precision threading applications
• WXS coating reduces cutting friction and extends tool life in a range of workpiece materials
• 3-flute helical design enables single-pass internal thread milling via CNC interpolation
• 6-32 UNC thread profile with 32 TPI and right-hand thread and flute direction
• 0.25-inch shank diameter fits standard CNC toolholders without adapters
• No coolant-through design — suitable for external flood or mist coolant delivery

Compatibility

Designed for use in CNC machining centers capable of helical interpolation for internal thread milling of 6-32 UNC threads.

Installation Notes

Thread mills require CNC helical interpolation and must be programmed with the correct thread pitch, diameter offset, and helical lead before use. Ensure the toolholder and collet are correctly sized for the 0.25-inch shank and properly torqued before running. Verify spindle speed and feed rate parameters are set according to the material being threaded and the tool manufacturer recommendations. Always inspect the cutting edges for wear or chipping before each use.
