Micro 100 IT-290750 Internal Threading Tool Solid Carbide

Product Description

The MICRO 100 IT-290750 is a solid carbide single point internal threading tool designed for cutting threads inside bores and through-holes on CNC lathes and manual turning centers. It handles a thread range of 14 to 40 TPI with a 60-degree profile angle, making it suitable for unified and metric-compatible thread forms across that pitch range. The minimum threading diameter is 0.29 inches, and the tool reaches a cutting depth of 0.75 inches. Built from solid carbide with a bright, uncoated finish, it delivers rigidity and wear resistance in ferrous and non-ferrous applications. Machinists and toolroom operators working in precision production and job-shop environments will find this tool a reliable choice for internal thread generation.

This tool is suited for internal threading operations in both production and prototype machining environments. It fits standard 5/16-inch shank toolholders and boring bar setups common on CNC turning centers, engine lathes, and Swiss-style machines. The 0.07-inch projection from edge keeps the cutting geometry close to the holder centerline, reducing deflection in tight-bore applications. It is appropriate for threading aluminum, steel, stainless, brass, and similar materials within its rated TPI range.

Key Features

• Solid carbide construction for rigidity and extended tool life
• 60-degree profile angle compatible with unified thread forms across the 14 to 40 TPI range
• 0.29-inch minimum threading diameter for small-bore internal threading
• 0.75-inch cutting depth for threading deeper internal features
• 0.07-inch projection from edge minimizes deflection in confined bore geometry
• Bright, uncoated finish suitable for a broad range of workpiece materials

Compatibility

Designed for use in 5/16-inch shank internal threading toolholders and boring bar systems on CNC turning centers and manual lathes capable of single point threading operations.

Installation Notes

Installation and setup should be performed by a qualified machinist or toolroom technician. Power down and lock out the machine before inserting or removing the tool from the holder. Ensure the shank is fully seated and clamped to the toolholder manufacturer's specified torque using appropriate hex wrenches. Verify tool centerline height and clearance angles before initiating a threading pass.
