Osg 4100002211 Thread Mill 3/4-10 Unc 4 Flute Solid Carbide

Product Description

The OSG 4100002211 is a solid carbide helical flute thread mill designed for cutting 3/4-10 UNC internal threads in a single helical pass. With 4 right-hand flutes and an EXO coating, it delivers consistent thread form and extended tool life in ferrous and non-ferrous materials. The cutting diameter is 0.6200 inches with a length of cut of 1.2010 inches, making it well suited for through-hole and blind-hole thread milling applications on CNC machining centers. This tool belongs to OSG Series 41000 and is intended for use by machinists and tooling professionals in production and job-shop environments.

This thread mill is used in CNC milling operations where thread milling is preferred over tapping, particularly in hard materials, thin-walled parts, or applications requiring a single tool to produce a range of thread depths. The 3/4-10 UNC thread form and 0.7500 inch minimum nominal diameter make this tool appropriate for standard fastener hole applications in general machining, aerospace component work, and industrial manufacturing. The 5/8 inch shank diameter and 4.0000 inch overall length provide rigid tool holding in standard ER or end mill collet systems.

Key Features

• Solid carbide construction for rigidity and wear resistance in demanding thread milling operations
• EXO coating reduces friction and heat buildup, extending tool life in steel and alloy applications
• 4 right-hand helical flutes for efficient chip evacuation during thread milling
• Cuts 3/4-10 UNC threads with a 0.6200 inch cutting diameter and 1.2010 inch length of cut
• 4.0000 inch overall length with 5/8 inch shank fits standard collet and toolholder systems
• No coolant-through design simplifies toolholder selection and setup

Compatibility

Designed as an OEM-style thread milling tool for CNC machining centers capable of helical interpolation, compatible with standard 5/8 inch diameter collet chucks and end mill holders used in 3-axis and 4-axis milling applications.

Installation Notes

Thread milling with this tool requires a CNC machining center with helical interpolation capability programmed to the correct thread pitch and diameter. Verify toolholder runout before use, as excessive runout will degrade thread quality and reduce tool life. Confirm correct spindle speed and feed rate for the workpiece material prior to cutting. Always follow shop safety procedures and machine guarding requirements when changing or handling carbide tooling.
