Scientific Cutting Tools TT1801000A Threading Tool

Product Description

The SCIENTIFIC CUTTING TOOLS TT1801000A is a solid carbide single point internal threading tool engineered for precision thread cutting in small-bore applications. It handles a minimum threading diameter of 0.18 inches and covers a thread pitch range of 18 to 56 threads per inch (TPI), making it well suited for fine and coarse internal thread profiles. The tool features a 60-degree profile angle and a 1-inch cutting depth. The AlTiN+ coating provides elevated heat resistance and extended tool life in demanding cutting conditions. This tool is used by machinists and toolroom technicians working on CNC lathes, screw machines, and manual turning centers.

This threading tool is designed for internal threading operations in small-diameter bores. Its 0.25-inch shank diameter and 2.5-inch overall length make it compatible with standard tool holders in production and job-shop environments. The 0.04-inch projection from edge allows precise positioning within bore geometry. It handles thread forms with a 60-degree included angle, covering the most common unified and metric thread profiles. Applications include threading hydraulic fittings, instrumentation components, and precision mechanical assemblies where controlled thread geometry is required.

Key Features

• Internal threading capability starting at 0.18 inches minimum thread diameter
• Thread pitch range of 18 to 56 TPI for broad coverage of common thread sizes
• Solid carbide construction for rigidity and dimensional stability
• AlTiN+ coating for improved wear resistance and heat tolerance
• 60-degree profile angle compatible with unified and standard metric thread forms
• 1-inch cutting depth with 0.04-inch projection from edge for bore entry control

Compatibility

Designed as an OEM-style single point internal threading tool for use in standard 0.25-inch shank tool holders on CNC and manual turning equipment.

Installation Notes

Installation is performed by qualified machinists or toolroom technicians. Secure the 0.25-inch shank firmly in the appropriate tool holder and verify zero runout before threading operations begin. Power down the machine and lock out energy sources before changing or adjusting the tool. Do not exceed the tool's rated cutting depth or minimum bore diameter to avoid deflection and thread form error.
