Accupro SAT2901250-12 Threading Tool 12 Tpi Internal Carbide

Product Description

The ACCUPRO SAT2901250-12 is a solid carbide single point threading tool designed for internal thread cutting on CNC lathes and manual turning centers. It features a 29-degree profile angle and cuts threads at 12 TPI with a minimum threading diameter of 0.23 inches and a cutting depth of 1.25 inches. The bright, uncoated carbide construction provides a sharp edge suitable for threading ferrous and non-ferrous materials. With a 5/16-inch shank diameter and 2.5-inch overall length, this tool fits standard boring bar-style holders used in production and job shop environments. Machinists and tool-and-die professionals typically spec this style of insert for precision internal threading passes.

This tool is suited for internal threading operations in residential and industrial machine shop settings, including production turning, repair work, and custom thread form generation. The 0.07-inch projection from edge and 0.033-inch flat width make it appropriate for fine-pitch internal threads in tight-bore applications. It is sold individually and is a practical choice for operators needing a dedicated single-point threading tool without coolant-through requirements.

Key Features

• Solid carbide construction for rigidity and long tool life in internal threading applications
• 29-degree profile angle for accurate thread form geometry
• 12 TPI maximum threads per inch capacity
• 1.25-inch cutting depth accommodates deeper internal threading passes
• Bright, uncoated finish maintains sharp edge geometry out of the package
• No coolant-through requirement simplifies setup on standard holders

Compatibility

Designed as an OEM-style single point threading tool for use in standard 5/16-inch shank boring bar holders on CNC and manual lathes performing internal threading operations.

Installation Notes

Installation is performed by qualified machinists or toolroom technicians. Ensure the machine spindle is fully stopped and the tool holder is securely clamped before inserting or removing the tool. Confirm shank diameter compatibility with the holder bore before tightening. Follow shop-standard tool stick-out and runout procedures to maintain thread accuracy and avoid tool deflection during the threading pass.
