Micro 100 IT-2901750X Internal Threading Tool Solid Carbide

Product Description

The MICRO 100 IT-2901750X is a solid carbide single point internal threading tool designed for precision thread cutting in bores and internal features. It handles a minimum threading diameter of 0.29 inches and supports a thread range of 14 to 40 threads per inch (TPI), making it versatile across a wide range of internal thread profiles. The 60-degree profile angle covers unified and metric thread forms commonly encountered in machining work. A cutting depth of 1.75 inches allows threading in deeper bores without tool change-out. The AlTiN coating improves heat resistance and tool life in demanding materials. Machinists and tool-and-die professionals are the primary users of this tool.

This tool is suited for internal threading operations on CNC lathes and manual turning centers in job shops, production machining environments, and toolroom settings. The 5/16-inch shank diameter and 2.5-inch overall length make it compatible with standard boring bar holders and quick-change tooling systems. Its solid carbide construction provides the rigidity needed for consistent thread form in ferrous and non-ferrous materials. The 0.07-inch projection from edge allows the tool to engage the workpiece cleanly in tight bore conditions.

Key Features

• Solid carbide construction for rigidity and extended tool life in demanding machining applications
• Covers 14 to 40 TPI range for versatility across common internal thread specifications
• 60-degree profile angle suits unified national and comparable thread forms
• AlTiN coating provides elevated heat and wear resistance
• 1.75-inch cutting depth supports threading in deeper internal features
• 0.07-inch projection from edge for clean engagement in confined bores

Compatibility

Designed as an OEM-style replacement and standard fitment for CNC and manual lathe tooling systems accepting a 5/16-inch shank internal threading bar.

Installation Notes

Installation is performed by a qualified machinist or toolroom technician. Secure the shank firmly in the tool holder and verify runout before engaging the workpiece. Power down and de-energize the machine spindle before setting tool height or adjusting the holder. Follow machine manufacturer guidelines for feed rate and depth of cut when threading to avoid chipping the carbide insert tip.
