Micro 100 IT-290500 Internal Threading Tool Solid Carbide

Product Description

The MICRO 100 IT-290500 is a single point internal threading tool machined from solid carbide for use in CNC lathes and manual turning centers. It handles a threading range of 14 to 40 TPI with a minimum thread diameter of 0.29 inches and a cutting depth of 0.5 inches. The 60-degree profile angle suits Unified National thread forms. The bright, uncoated finish keeps the cutting edge geometry consistent and works well in a wide range of ferrous and non-ferrous materials. Machinists and toolroom operators select this tool for precision internal thread cutting where rigidity and dimensional accuracy are critical.

This tool is intended for internal threading operations on bore diameters at or above 0.29 inches. The 5/16-inch shank fits standard toolholders used in production turning, job shop, and maintenance machining environments. A 0.07-inch projection from the edge provides clearance at the bore entrance. With a 2.5-inch overall length, the tool fits compact toolpost and gang-style setups without excessive overhang. Suitable for residential and industrial shop applications wherever repeatable thread form accuracy is required in internal bores.

Key Features

• Solid carbide construction for rigidity and wear resistance in internal threading
• Covers 14 to 40 TPI range with a single tool, reducing changeover time
• 60-degree profile angle compatible with Unified National thread forms
• Minimum thread diameter of 0.29 inches suits small-bore internal threading
• Bright/uncoated finish preserves sharp edge geometry across material types
• No coolant-through design simplifies setup in standard toolholders

Compatibility

Designed as an OEM-style single point threading insert for use in toolholders accepting a 5/16-inch round shank, suitable for CNC and manual lathes configured for internal threading operations.

Installation Notes

Installation is performed by qualified machinists following standard lathe toolsetting procedures. Secure the shank fully in the toolholder and confirm center height before engaging the workpiece. Power down the machine and lock out all energy sources before changing or adjusting tooling. Verify thread pitch and direction settings on the machine control before cutting to avoid tool or workpiece damage.
