Accupro Acc -T200400 Single Point Threading Tool

Product Description

The ACCUPRO ACC -T200400 is a solid carbide single point threading tool designed for internal thread cutting operations on CNC lathes and manual turning centers. It features a 60-degree profile angle and covers a threading range of 16 to 40 TPI with a minimum thread diameter of 0.2 inches. The 0.4-inch cut depth and 0.045-inch projection from edge make it well suited for precision thread forms in tight bores. The bright, uncoated solid carbide construction provides rigidity and edge retention for consistent thread profiles in ferrous and non-ferrous materials. Machinists and CNC operators install this tool as part of a standard boring bar or threading holder setup.

This tool is used for internal threading in production machining environments, job shops, and toolrooms. It mounts via a 1/4-inch shank into compatible toolholders and is appropriate for threading operations where a 60-degree unified or metric-style profile is required. The 2.5-inch overall length accommodates standard reach requirements on most lathe setups. It is well suited for applications requiring consistent thread form across the 16 to 40 TPI range in small-bore internal features.

Key Features

• Solid carbide construction for rigidity and edge retention
• 60-degree profile angle for unified and standard metric thread forms
• Threading range of 16 to 40 TPI covers a broad range of common thread pitches
• 0.2-inch minimum thread diameter for small-bore internal threading
• 0.4-inch cut depth for full thread engagement in typical bore depths
• Bright, uncoated finish suitable for use with or without coolant on most materials

Compatibility

Designed for use with 1/4-inch shank threading toolholders on CNC and manual lathes capable of single point threading operations. Compatible with standard 60-degree internal threading applications across the 16 to 40 TPI range.

Installation Notes

Installation is performed by qualified machinists or CNC operators. The tool shank should be secured firmly in a compatible 1/4-inch bore toolholder with appropriate set screws torqued per the toolholder manufacturer's specification. Ensure the machine spindle is fully stopped and the lathe is in a safe state before mounting or removing the insert. Do not exceed the rated cut depth or minimum thread diameter to avoid tool deflection or breakage.
