Scientific Cutting Tools TT180500 Threading Tool Internal

Product Description

The SCIENTIFIC CUTTING TOOLS TT180500 is a solid carbide single point threading tool designed for internal thread cutting operations on CNC lathes and turning centers. It handles a minimum threading diameter of 0.18 inches and covers a thread pitch range of 18 to 56 TPI, making it suitable for a wide range of fine and coarse internal thread profiles. The 60-degree profile angle conforms to standard Unified and metric thread forms. With a 0.5-inch cutting depth and a bright, uncoated carbide substrate, this tool delivers consistent thread geometry in ferrous and non-ferrous materials. Machinists and toolroom professionals install and operate this tool in production and job-shop turning environments.

This tool is used for internal threading passes on bored or drilled features in workpieces held in CNC or manual lathes. The 0.25-inch shank diameter fits standard boring bar-style toolholders and quick-change setups common in small-bore internal threading applications. At 2.5 inches overall length, it provides adequate reach for shallow to moderate bore depths. The bright uncoated finish suits applications where coating interaction with workpiece material or cutting fluid chemistry is a concern. It is a single-quantity item suited for prototype work, low-volume production, or toolroom use.

Key Features

• Solid carbide construction for rigidity and wear resistance in internal threading
• Covers 18 to 56 TPI thread pitch range with a 60-degree profile angle
• Minimum threading diameter of 0.18 inches for small-bore internal threads
• 0.5-inch cutting depth with 0.04-inch projection from edge
• 0.25-inch shank diameter fits standard small-bore toolholders
• Bright, uncoated finish with no coolant-through requirement

Compatibility

Designed as an OEM-style single point threading insert tool for use in standard 0.25-inch shank toolholders on CNC and manual lathes performing internal thread cutting operations.

Installation Notes

Installation and operation of this tool should be performed by a qualified machinist familiar with single point threading cycles and lathe operation. Secure the shank firmly in the toolholder to the full recommended engagement depth before beginning a threading pass. Confirm spindle speed, feed rate, and threading cycle parameters in the machine controller match the target TPI before engaging the workpiece. Inspect the carbide tip for chipping or wear before each use, as solid carbide tools can fracture if subjected to interrupted cuts or excessive radial load.
