Micro 100 IT-3601000 Internal Threading Tool Solid Carbide

Product Description

The MICRO 100 IT-3601000 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 threading diameter of 0.36 inches with a cutting depth of 1 inch, covering a thread range of 11 to 28 TPI. The 60-degree profile angle suits Unified National (UN) thread forms commonly used in general machining work. With a bright, uncoated finish and full solid carbide construction, the tool delivers consistent performance on ferrous and non-ferrous materials. Machinists and tool-and-die tradespeople rely on this geometry for bore threading where rigid setup and precise insert positioning are required.

This tool is suited for internal threading operations in production and job-shop environments. The 3/8 inch shank diameter fits standard boring bar holders and quick-change tooling systems on lathes in that size range. At 2.5 inches overall length, it is sized for moderate bore depths without excessive overhang. Typical applications include threading hydraulic fittings, valve bodies, couplings, and other components requiring machined internal thread forms in the 11 to 28 TPI range.

Key Features

• Solid carbide construction for rigidity and wear resistance in threading operations
• 60-degree profile angle compatible with Unified National thread forms
• Covers 11 to 28 TPI range in a single tool geometry
• 0.36 inch minimum threading diameter suits small to mid-range bore work
• Bright uncoated finish - no coating buildup to affect thread profile accuracy
• No coolant-through requirement simplifies setup on standard lathes

Compatibility

Designed as a direct-fit replacement or standard tooling selection for lathes and CNC turning centers accepting a 3/8 inch shank boring bar or threading tool holder.

Installation Notes

Installation is performed by qualified machinists or toolroom personnel. Secure the shank firmly in the tool holder and verify center height alignment before threading to avoid thread form errors. Ensure the spindle is fully stopped and the machine is in a safe state before changing or adjusting the tool. Follow machine manufacturer guidelines for tool overhang limits to minimize chatter during internal threading passes.
