Scientific Cutting Tools TT200400A Threading Tool 16-40 Tpi

Product Description

The SCIENTIFIC CUTTING TOOLS TT200400A is a solid carbide single point threading tool designed for internal thread cutting operations on CNC lathes and turning centers. Built from solid carbide with an AlTiN+ coating, the tool handles thread pitches from 16 to 40 TPI using a 60-degree profile angle. The 0.2-inch minimum threading diameter and 0.4-inch cutting depth make it suited for small-bore internal threading work where rigidity and edge retention are critical. The AlTiN+ finish provides heat and wear resistance, extending tool life during dry or semi-dry cutting conditions. Machinists and CNC operators working in production or job-shop environments rely on this tool for consistent thread form in tight-tolerance bores.

This tool is configured for internal threading applications across a range of materials commonly encountered in precision machining, including steel, stainless steel, and cast iron. The 1/4-inch shank diameter fits standard boring bar holders and quick-change tooling systems. With a 2.5-inch overall length and 0.045-inch projection from the edge, it is well suited for threading shallow to moderate-depth bores in residential and commercial component manufacturing environments. No coolant-through capability is present, so chip evacuation management is the responsibility of the operator based on material and depth of cut.

Key Features

• Solid carbide construction for rigidity and extended tool life in internal threading
• AlTiN+ coating for improved heat resistance and wear performance during dry cutting
• 16 to 40 TPI range with a 60-degree profile angle for unified thread forms
• 0.2-inch minimum threading diameter for small-bore internal applications
• 0.4-inch cutting depth with 0.045-inch projection from edge for controlled engagement
• 1/4-inch shank diameter compatible with standard CNC tooling holders

Compatibility

Designed as an OEM-style single point threading tool for use in CNC lathes and turning centers equipped with 1/4-inch shank toolholders supporting internal threading operations.

Installation Notes

Installation and setup should be performed by a qualified machinist or CNC tooling technician. Power down and lock out the machine before mounting or removing the tool from the holder. Ensure the shank is seated fully and clamped securely in the toolholder before operation. Verify thread pitch and profile settings in the machine control before initiating a threading pass.
