Osg 1662502117 Thread Mill 3/4-10 Unc 5 Flute Solid Carbide

Product Description

The OSG 1662502117 is a solid carbide helical flute thread mill designed for cutting 3/4-10 UNC threads in both internal and external applications. With 5 right-hand flutes and a cutting diameter of 0.461 inches, it delivers precise thread geometry in a single helical interpolation pass. The EgiAs coating provides wear resistance for extended tool life in demanding materials. The 0.5 inch shank diameter suits standard milling chucks and collet holders. This tool is installed and operated by machinists and CNC programmers in job shop, production, and maintenance machining environments.

This thread mill is suited for use on CNC machining centers capable of helical interpolation. It handles both internal and external 3/4-10 UNC thread profiles, making it a versatile single-tool solution when threading blind holes or external bosses where tap-style tooling is impractical. With a length of cut of 1.7 inches, it accommodates threads in deeper features without requiring a secondary operation. Typical applications include aerospace, industrial, and general metalworking setups where thread quality and tool life consistency are priorities.

Key Features

• Solid carbide construction for rigidity and dimensional stability
• EgiAs coating for enhanced wear resistance and reduced friction
• 5 right-hand helical flutes for smooth chip evacuation
• Cuts both internal and external 3/4-10 UNC threads in a single tool
• 0.461 inch cutting diameter with 1.7 inch length of cut for deeper thread engagement
• No coolant-through design — external coolant or mist lubrication applies

Compatibility

Designed for use on CNC machining centers with helical interpolation capability and standard 0.5 inch collet or end mill holders; compatible with 3/4-10 UNC thread specifications per standard UNC thread form requirements.

Installation Notes

Installation and operation should be performed by a qualified machinist or CNC programmer familiar with helical interpolation toolpaths. Secure the shank in a properly sized collet or milling chuck and verify runout before cutting. Consult the machine tool manufacturer and OSG application data for appropriate cutting speeds, feed rates, and depth of cut — do not estimate these values from general end mill guidelines. Inspect the tool edge condition before each run, as carbide tooling is brittle and susceptible to chipping if dropped or improperly stored.
