Accupro Acc -T2901000 Single Point Threading Tool

Product Description

The ACCUPRO ACC -T2901000 is a single point threading tool engineered for internal thread cutting on CNC lathes and manual turning equipment. Built from solid carbide, it delivers the hardness and wear resistance required for consistent thread form in production and job-shop environments. The tool covers a threading range of 12 to 40 TPI with a 60-degree profile angle, a minimum thread diameter of 0.29 inches, and a cutting depth of 1 inch. The bright, uncoated finish makes it straightforward to inspect for wear. Machinists and tool-and-die professionals working in precision turning operations will find this a dependable single-point insert-style tool for internal threading applications.

This tool is suited for internal threading operations on bores measuring 0.29 inches and larger. It is typically used in CNC turning centers and manual lathes where a solid carbide, fixed-point tool is preferred over an indexable insert system. The 5/16-inch shank diameter fits standard boring bar holders and quick-change tooling systems. The 2.5-inch overall length allows reach into moderate-depth bores without excessive overhang. It is a practical choice for threading ductile and ferrous materials where the 60-degree unified or metric-compatible profile is required.

Key Features

• Solid carbide construction for hardness and extended tool life in internal threading
• 60-degree profile angle compatible with unified thread standards
• Threading range of 12 to 40 TPI in a single tool
• Minimum thread diameter of 0.29 inches for small-bore internal work
• 1-inch cutting depth for threading deeper internal features
• Bright, uncoated finish allows clear visual wear inspection
• 5/16-inch shank fits common boring bar and quick-change holders

Compatibility

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

Installation Notes

Installation and tool changes should be performed with the machine in a powered-down, locked-out state per applicable safety procedures. Solid carbide tooling is brittle and should be clamped securely with proper tool holder torque to prevent micro-fracture from vibration or interrupted cuts. Overhang beyond the minimum required depth should be minimized to reduce deflection and protect the carbide shank. A qualified machinist or toolroom technician should verify thread form and pitch with appropriate gauging before running a production cycle.
