Micro 100 IT-230750 Internal Threading Tool Solid Carbide

Product Description

The MICRO 100 IT-230750 is a solid carbide single point internal threading tool designed for cutting internal threads on CNC lathes and manual turning centers. It handles a minimum thread diameter of 0.23 inches and covers a thread pitch range of 20 to 48 threads per inch (TPI) with a 60-degree profile angle, making it suitable for unified and metric-profile internal thread forms. The 0.75-inch cutting depth allows access into deeper bores without requiring a tool change. Machinists and toolroom technicians use this tool when precision internal threading is required in tight-diameter applications.

This tool is suited for internal threading operations in production and job-shop environments where consistent thread form and dimensional accuracy are critical. The bright, uncoated finish keeps replacement cost low for general-purpose use in non-abrasive materials. 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 commonly found on manual and CNC turning equipment.

Key Features

• Solid carbide construction provides rigidity and wear resistance for internal threading operations
• 60-degree profile angle covers standard unified thread forms
• 20 to 48 TPI range handles fine and coarse pitch internal threads in a single tool
• 0.75-inch cutting depth allows threading into deeper bores
• 0.055-inch projection from edge for clearance in confined bore entries
• Bright/uncoated finish for general-purpose threading without coating-related diameter offset concerns

Compatibility

Designed as an OEM-style single point internal threading tool for use in standard 5/16-inch shank boring bar holders and quick-change tool blocks on CNC and manual turning centers requiring 20 to 48 TPI internal thread capability.

Installation Notes

Installation is performed by a qualified machinist or toolroom technician. Secure the tool in a compatible 5/16-inch shank holder and confirm tool centerline height before threading. Power down and lock out the machine spindle before changing or adjusting the insert. Follow the machine manufacturer guidelines and applicable shop safety standards when setting thread depth and feed parameters.
