Accupro Acc -T490750 Single Point Threading Tool

Product Description

The ACCUPRO ACC -T490750 is a solid carbide single point threading tool designed for internal thread cutting operations on CNC lathes and manual turning centers. It handles a minimum threading diameter of 0.49 inches, a cutting depth of 0.75 inches, and covers a thread range of 8 to 32 TPI. The 60-degree profile angle makes it suited for standard unified and metric-profile internal threads. With a 1/2-inch shank diameter and a 3-inch overall length, it mounts securely in standard boring bar-style holders. The bright/uncoated solid carbide construction provides rigidity and edge retention in ferrous and non-ferrous materials.

This tool is used in precision machining environments where internal threads must be cut to tight tolerances in bores at or above 0.49 inches in diameter. It is appropriate for job shops, production machining cells, and maintenance machine work where a single point insert-style or solid threading tool is required. The 0.12-inch projection from the edge allows controlled engagement in confined bore geometries. Machinists and CNC operators performing thread milling or single point threading passes on turning equipment are the primary users of this tool.

Key Features

• Solid carbide construction for rigidity and edge life in demanding threading operations
• Internal thread cutting with a 60-degree profile angle for standard thread forms
• 0.49 inches minimum threading diameter suits a wide range of bore sizes
• 8 to 32 TPI range covers coarse and fine unified thread series
• 0.75 inches cutting depth allows threading of deeper internal features
• Bright/uncoated finish with no coolant-through requirement simplifies setup

Compatibility

Designed as an OEM-style single point threading tool for use in standard 1/2-inch shank tool holders on CNC and manual turning equipment capable of single point threading cycles.

Installation Notes

Installation is performed by qualified machinists or CNC operators. Ensure the machine spindle is fully stopped and the tool holding system is de-energized before mounting or removing the tool. Secure the 1/2-inch shank in a rigid tool holder to the manufacturer torque specifications for that holder. Verify tool projection, TPI setting, and depth-of-cut parameters in the control before initiating a threading pass.
