Scientific Cutting Tools TT4902000A Threading Tool Internal

Product Description

The SCIENTIFIC CUTTING TOOLS TT4902000A is a solid carbide single point threading tool designed for internal thread cutting operations. It produces 60-degree unified thread profiles and handles thread pitches from 8 to 32 TPI with a minimum threading diameter of 0.49 inches. The tool features an AlTiN+ coating for improved wear resistance and heat tolerance in demanding machining environments. With a 2-inch cutting depth and a 1/2-inch shank diameter, it fits standard CNC lathe and mill-turn toolholders. This tool is installed and used by machinists and toolroom professionals working in precision manufacturing and production environments.

The TT4902000A is suited for internal threading operations on CNC lathes, turning centers, and mill-turn machines. It is appropriate for both production runs and job-shop applications where consistent thread form and tight tolerances are required. The 60-degree profile makes it compatible with standard unified and metric thread forms that share that included angle. Its 2-inch cut depth accommodates threading in deeper bores where shorter tools would not reach.

Key Features

• Solid carbide construction for rigidity and wear resistance in internal threading
• AlTiN+ coating extends tool life in high-temperature cutting conditions
• 60-degree profile angle for unified thread form compatibility
• 8 to 32 TPI range covers a broad selection of common thread pitches
• 2-inch cutting depth allows threading in deeper bore applications
• 0.12-inch projection from edge for clearance in tight internal geometries

Compatibility

Designed as a replacement or production single point threading insert tool for CNC lathes and turning centers using 1/2-inch round shank toolholders requiring internal threading capability in the 8 to 32 TPI range.

Installation Notes

Installation is performed by machinists or toolroom technicians on CNC turning or mill-turn equipment. The machine spindle must be brought to a full stop and all axes must be at a safe home position before changing or setting tooling. Confirm shank clamping torque meets the toolholder manufacturer specification and verify tool projection and runout with a dial indicator before cutting. Do not exceed the tool's stated minimum bore diameter to avoid deflection or chatter.
