Accupro FAT1801000-16 Threading Tool 16 Tpi Internal Carbide

Product Description

The ACCUPRO FAT1801000-16 is a single point internal threading tool ground from solid carbide for use on CNC lathes and manual threading operations. It cuts internal threads starting at a minimum diameter of 0.18 inches with a cutting depth of 1 inch and runs at 16 threads per inch (TPI). The 29-degree profile angle suits standard unified thread forms. The tool ships bright and uncoated, which suits machining operations where coating is not required or where the operator will apply their own surface treatment. Machinists and toolroom technicians install this tool in a 1/4-inch shank holder for precision internal thread work on ferrous and non-ferrous materials.

This threading insert tool is intended for internal thread generation in production and job-shop environments. The 0.045-inch projection from edge and 0.021-inch flat width support controlled chip formation and accurate thread profile reproduction. It is suited for light-duty internal threading passes on small-bore workpieces where rigidity and dimensional accuracy are critical. Typical applications include threading small hydraulic fittings, instrument housings, and fluid-system components requiring consistent 16 TPI internal threads.

Key Features

• Solid carbide construction for rigidity and wear resistance in internal threading operations
• 16 TPI capacity with a 29-degree profile angle for standard unified thread forms
• Minimum threading diameter of 0.18 inches for small-bore internal applications
• 1-inch cutting depth and 0.045-inch projection from edge for controlled thread engagement
• 1/4-inch shank diameter and 2.5-inch overall length for compatibility with standard boring bar holders
• Bright/uncoated finish — ready to use as supplied or suitable for operator-applied coatings

Compatibility

Designed as an OEM-style solid carbide threading tool for use in standard 1/4-inch shank internal threading tool holders on CNC and manual lathes performing 16 TPI internal thread operations.

Installation Notes

This tool is installed by a qualified machinist or toolroom technician. The machine spindle must be fully stopped and the toolholder secured before inserting or adjusting the tool. Confirm shank diameter compatibility with the boring bar or toolholder before mounting. Follow the machine manufacturer guidelines and applicable shop-safety procedures when setting tool projection and running threading cycles.
