Micro 100 QIT-180750X Internal Single Point Threading Tool

Product Description

The MICRO 100 QIT-180750X is a solid carbide internal single point threading tool designed for cutting internal threads on CNC lathes and turning centers. It handles a minimum thread diameter of 0.18 inches and covers a thread pitch range of 27 to 56 TPI, making it well-suited for fine-pitch internal threading operations. The tool features a 60-degree profile angle, a 0.75-inch cutting depth, and a 0.25-inch round shank with an overall length of 2 inches. An AlTiN coating improves heat resistance and wear life in dry or semi-dry cutting environments. Machinists and CNC operators use this tool when threading small-bore internal features that require consistent geometry and tight tolerances.

This threading tool is intended for internal thread-cutting applications on small-diameter bores in ferrous and non-ferrous workpiece materials. It is a strong fit for production turning environments where fine-pitch threads are common, such as hydraulic fittings, medical components, and precision instrument housings. The 0.04-inch projection from the edge and solid carbide construction provide rigidity and predictable tool life in repetitive cycle operations. No coolant-through capability is present, so external coolant or air blast should be used to manage chip evacuation and heat at the cutting zone.

Key Features

• Solid carbide construction for rigidity and long tool life in demanding threading applications
• AlTiN coating provides elevated heat resistance and reduced wear in high-speed dry cutting
• 60-degree profile angle covers standard unified and metric-style thread forms
• Minimum thread diameter of 0.18 inches enables threading in tight small-bore applications
• Wide TPI range of 27 to 56 allows flexibility across fine-pitch thread specifications
• 0.25-inch shank diameter is compatible with standard collet and toolholder systems

Compatibility

Designed for use in CNC lathes and turning centers equipped with 0.25-inch collet holders or compatible toolholders that accept a 0.25-inch round shank single point threading insert-style tool.

Installation Notes

Installation and setup should be performed by a qualified CNC machinist or tooling specialist. Ensure the machine spindle is fully stopped and the turret is in a safe index position before mounting or removing the tool. Verify shank seating and runout before commencing threading cycles. Chip evacuation is critical on internal operations with no coolant-through capability, so confirm external coolant or air blast is directed at the cutting zone prior to running production cycles.
