Accupro FAT180750-16 Threading Tool 16 Tpi Internal Carbide

Product Description

The ACCUPRO FAT180750-16 is a single point internal threading tool ground from solid carbide and designed for CNC lathes and manual turning centers. It handles internal threads starting at 0.18 inches minimum thread diameter, cuts to a depth of 0.75 inches, and runs at 16 threads per inch (TPI) with a 29-degree profile angle. The 0.25 inch round shank and 2.5 inch overall length suit compact boring bar setups common in production and job shop environments. Machinists and CNC operators install this tool when threading blind or through bores where a solid carbide grade is preferred for rigidity and wear life.

This tool is suited for internal threading operations on ferrous and non-ferrous materials in both production and prototype turning work. The bright, uncoated finish makes it a practical choice when thread geometry precision matters more than coating-related rake modification. The 0.045 inch projection from edge and 0.021 inch flat width support consistent thread form on fine-pitch internal profiles. It fits standard 0.25 inch bore threading tool holders used across a wide range of turning setups.

Key Features

• Solid carbide construction for rigidity and extended tool life in internal threading applications
• 16 TPI cutting capacity with a 29-degree profile angle for accurate thread form
• 0.18 inch minimum thread diameter suits small-bore internal threading
• 0.75 inch cutting depth accommodates deeper internal thread lengths
• 0.25 inch shank diameter fits standard threading tool holders
• Bright, uncoated finish preserves as-ground geometry without coating buildup

Compatibility

Designed as an OEM-style replacement or direct-fit threading insert for standard 0.25 inch shank internal threading tool holders used in CNC and manual turning applications.

Installation Notes

Installation is performed by qualified machinists or CNC setup technicians. Power down and lock out the lathe spindle before seating or adjusting the tool in the holder. Verify shank clamping torque against the tool holder manufacturer specification and confirm tool centerline height before threading. Do not exceed the rated cutting depth of 0.75 inches per pass without validating rigidity of the setup.
