Micro 100 IT-2901000 Internal Threading Tool Solid Carbide

Product Description

The MICRO 100 IT-2901000 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 0.29 inches and covers a thread pitch range of 14 to 40 TPI, making it a versatile choice for a wide range of standard internal thread profiles. The 60-degree profile angle suits Unified (UN) and metric-profile threads. With a 1-inch cutting depth capacity and a bright, uncoated carbide blank, this tool is built for machinists and toolroom professionals who need consistent thread geometry in bores and through-holes.

This tool is suited for internal threading operations in production machining, job-shop turning, and toolroom work. The 5/16-inch shank diameter keeps the tool compact enough for smaller bore entries while maintaining rigidity during the threading pass. The 0.07-inch projection from the cutting edge and the 2.5-inch overall length are appropriate for typical lathe toolholding setups. It is commonly used in aerospace, industrial, and general manufacturing environments where precise internal thread form is required on steel, aluminum, and similar machinable materials.

Key Features

• Solid carbide construction for wear resistance and dimensional stability during threading passes
• 60-degree profile angle compatible with Unified and similar thread forms
• 14 to 40 TPI range covers a broad selection of standard internal thread pitches
• 1-inch cutting depth supports threading into deeper bores without tool change
• Bright/uncoated finish suitable for a wide range of base materials
• No coolant-through design - external coolant or cutting oil applied at the entry point

Compatibility

Designed as an OEM-style single point threading insert tool for use in standard 5/16-inch bore toolholders and compatible lathe or CNC turning toolholding systems accepting a 5/16-inch round shank.

Installation Notes

Installation and use should be performed by a qualified machinist or CNC programmer. Power down and lock out the spindle before mounting or removing the tool from the toolholder. Confirm shank clamping torque and tool overhang meet the toolholder manufacturer specifications before initiating a threading cycle. Apply cutting fluid or coolant externally at the bore entry to reduce heat and improve thread surface finish.
