Accupro FAT290750-12 Threading Tool 12 Tpi Internal Carbide

Product Description

The ACCUPRO FAT290750-12 is a single point internal threading tool ground from solid carbide for use on CNC lathes and manual turning centers. It handles internal thread forms with a minimum threading diameter of 0.29 inches and a cutting depth of 0.75 inches. The 29-degree profile angle suits standard thread forms, and the bright uncoated finish allows machinists to visually inspect the cutting edge before and after use. With a 5/16 inch shank diameter and an overall length of 2.5 inches, this tool fits standard boring bar-style holders used in production and job-shop turning operations. Machinists and tool-and-die professionals working in steel, aluminum, and similar machinable materials are the primary users.

This tool is suited for internal threading operations on lathes equipped with threading cycles, including both CNC and manual setups where single point threading is required. The 12 TPI maximum thread rate and the 0.07 inch projection from the edge make it appropriate for threading operations where precise depth and profile control are critical. It is sold individually and is a direct addition to standard tooling inventories for production threading work.

Key Features

• Solid carbide construction for rigidity and wear resistance in internal threading applications
• 29-degree profile angle for standard thread form compatibility
• 12 TPI maximum threads per inch capacity
• 0.75 inch cutting depth supports threading in blind and through-hole configurations
• Bright uncoated finish allows clear edge inspection and suits a wide range of workpiece materials
• 5/16 inch shank diameter fits common internal threading and boring bar holders

Compatibility

Designed as an OEM-style single point threading insert tool for use in standard 5/16 inch shank internal threading toolholders on CNC and manual lathes.

Installation Notes

Installation and use should be performed by a qualified machinist familiar with lathe tooling and threading cycle programming or manual thread-cutting procedures. Power down and lock out the lathe spindle before seating or removing the tool from the holder. Verify shank clamp torque per the toolholder manufacturer specification and confirm tool projection and centerline height before engaging the threading cycle. Do not exceed the rated cutting depth of 0.75 inches.
