Micro 100 IT-2901750 Internal Threading Tool Solid Carbide

Product Description

The MICRO 100 IT-2901750 is a solid carbide single point internal threading tool designed for precision thread cutting on CNC lathes and manual turning equipment. Built with a 60-degree profile angle, it cuts internal threads with a minimum threading diameter of 0.29 inches and handles a thread pitch range of 14 to 40 TPI. The 1.75-inch cut depth allows access into deeper bores without tool interference. The bright, uncoated carbide construction holds a sharp edge on a wide range of workpiece materials. Machinists and tool and die professionals reach for this tool when thread form accuracy and bore clearance are both critical to the job.

The IT-2901750 is suited for internal threading operations in production and job-shop environments. It mounts via a 5/16-inch diameter shank, making it compatible with standard boring bar holders and quick-change tooling systems on CNC and manual lathes. With an overall length of 2.5 inches and a 0.07-inch projection from edge, the geometry is configured to reach internal thread features while maintaining tool rigidity. This tool is appropriate for threading passes on bores in steel, aluminum, brass, and similar machinable metals.

Key Features

• Solid carbide construction for rigidity and edge retention in internal threading applications
• 60-degree profile angle for standard unified and metric-compatible thread forms
• 14 to 40 TPI range covers a broad spectrum of common internal thread pitches
• 1.75-inch cut depth provides access to deeper internal bore features
• 0.29-inch minimum threading diameter supports smaller bore work
• Bright, uncoated finish - ready to run as delivered, no break-in required

Compatibility

Designed for use in standard 5/16-inch shank boring bar holders and quick-change toolpost systems on CNC and manual lathes. Suitable for internal threading operations requiring a 60-degree thread profile.

Installation Notes

Installation is performed by a qualified machinist. Secure the 5/16-inch shank firmly in the toolholder to the holder manufacturer's specification before beginning any threading pass. Ensure the spindle is fully stopped and the machine is in a safe state before tool changes. Do not exceed the tool's stated minimum bore diameter, as doing so risks tool deflection and thread form error.
