Accupro Acc -T230400 Single Point Threading Tool

Product Description

The ACCUPRO ACC -T230400 is an internal single point threading tool ground from solid carbide for use on CNC lathes and manual threading operations. It handles a minimum thread diameter of 0.23 inches with a cutting depth of 0.4 inches, covering a thread range of 14 to 40 TPI. The 60-degree profile angle suits unified and metric thread forms. With a bright/uncoated finish and solid carbide construction throughout, this tool delivers consistent edge geometry and dimensional accuracy across a wide range of threading passes. Machinists and tool and die technicians rely on it for internal threading where tool rigidity and shank concentricity matter.

This tool is suited for internal threading applications in production and job shop environments. The 5/16-inch shank and 2.5-inch overall length make it compatible with standard boring bar holders and small-bore threading setups. The 0.055-inch projection from edge provides clearance geometry appropriate for close-tolerance threading in through-holes and blind bores. It is typically used in ferrous and non-ferrous materials where a solid carbide blank offers the stiffness needed to hold thread form at smaller diameters.

Key Features

• Solid carbide construction for rigidity and wear resistance in internal threading
• 60-degree profile angle compatible with unified and metric thread forms
• Thread range of 14 to 40 TPI from a single tool
• 0.23-inch minimum thread diameter for small-bore internal applications
• 0.055-inch projection from edge for proper clearance geometry
• Bright/uncoated finish suitable for use with or without cutting fluid

Compatibility

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

Installation Notes

Installation is performed by a machinist or tool and die technician. Secure the shank fully in the tool holder to the manufacturer-specified grip length before threading operations begin. Confirm tool centerline height is set correctly relative to the workpiece spindle center before engaging the cut. Do not exceed the rated cutting depth per pass or the stated maximum TPI range for this tool.
