Micro 100 IT-180750 Internal Threading Tool Solid Carbide

Product Description

The MICRO 100 IT-180750 is a solid carbide single point internal threading tool designed for cutting internal threads on a lathe or CNC turning center. It handles a minimum thread diameter of 0.18 inches and covers a thread pitch range of 27 to 56 TPI, making it suitable for fine-pitch internal threading work. The tool features a 60-degree profile angle, a 0.25-inch shank diameter, and a cutting depth capacity of 0.75 inches. At 2.5 inches overall length and 0.04 inches projection from edge, it is compact enough for close-tolerance boring and threading operations. Machinists and CNC operators in precision machining shops are the primary users.

This tool is suited for internal threading applications in small-diameter bores on ferrous and non-ferrous workpieces where fine thread pitches are required. It fits standard 0.25-inch bore toolholders and is appropriate for production and job-shop environments running lathe or turning operations. The bright, uncoated finish makes it well suited for non-ferrous materials such as aluminum and brass, as well as plastics, where coating adhesion is not a priority and raw carbide edge performance is preferred.

Key Features

• Solid carbide construction for rigidity and wear resistance in threading applications
• Covers 27 to 56 TPI range, accommodating a wide range of fine internal thread pitches
• 0.18-inch minimum thread diameter for small-bore internal threading
• 60-degree profile angle compatible with standard unified and metric thread forms at this angle
• Bright, uncoated finish suited for non-ferrous and plastic workpiece materials
• 0.25-inch shank diameter fits standard toolholders without adapters

Compatibility

Designed as an OEM-style single point threading insert tool for use in 0.25-inch bore internal threading toolholders on manual lathes and CNC turning centers.

Installation Notes

Installation and setup should be performed by a qualified machinist or CNC operator. Secure the shank fully in the toolholder to the recommended engagement depth before beginning any threading pass. Ensure the spindle is stopped and all axes are at a safe position before changing or indexing the tool. Follow the machine manufacturer guidelines for feed rate and spindle speed when threading at fine pitches to avoid tool deflection or workpiece damage.
