Accupro FAT180350-16 Threading Tool 16 Tpi Internal Carbide

Product Description

The ACCUPRO FAT180350-16 is a single point threading tool designed for internal thread cutting on CNC lathes and manual turning centers. Built from solid carbide with a bright uncoated finish, it handles a minimum threading diameter of 0.18 inches and cuts to a depth of 0.35 inches. The 29-degree profile angle suits standard thread forms, and the 0.25-inch shank provides rigid, low-vibration tool holding. With a 2.5-inch overall length and a 0.045-inch projection from edge, this tool suits tight-clearance internal threading operations. Machinists and CNC operators working in precision job shops or production environments install and run this tool.

This tool is suited for internal threading applications on small-diameter bores in ferrous and non-ferrous materials. The 16 threads per inch (TPI) geometry targets coarse-pitch thread cutting in components such as hydraulic fittings, valve bodies, and precision mechanical assemblies. The solid carbide construction supports use at higher surface speeds compared to high-speed steel alternatives, making it a practical choice for production runs where consistent thread form and tool life matter.

Key Features

• Solid carbide construction for rigidity and wear resistance at elevated cutting speeds
• 16 TPI thread profile for coarse-pitch internal threading
• 0.18 inch minimum threading diameter for small-bore applications
• 0.35 inch cutting depth capacity
• 29-degree profile angle for standard thread form accuracy
• Bright uncoated finish — no coolant-through requirement

Compatibility

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

Installation Notes

Installation is performed by qualified machinists or CNC setup technicians. Power down and lock out the machine spindle before seating or removing the tool in the holder. Ensure the shank is fully seated and the tool holder set screws are torqued to the holder manufacturer specification. Verify thread profile alignment with a thread gauge before beginning production cuts.
