Scientific Cutting Tools TT180500A Threading Tool Internal

Product Description

The SCIENTIFIC CUTTING TOOLS TT180500A is a solid carbide internal single point threading tool designed for precision thread cutting on CNC lathes and turning centers. It covers a threading range of 18 to 56 TPI with a 60-degree profile angle, making it suitable for a wide range of unified and metric-compatible thread forms on internal bores. The shank diameter is 0.25 inches and the overall length is 2.5 inches, keeping the tool compact for tight internal setups. An AlTiN+ coating improves wear resistance and heat tolerance at elevated cutting speeds. Machinists and CNC operators in precision machining shops are the primary installers of this tool.

This tool is suited for internal threading operations in production and job-shop environments where consistent thread form and tool life are priorities. The 0.18-inch minimum thread diameter and 0.5-inch cut depth make it a practical choice for small-bore threading on steel, stainless, and other ferrous and non-ferrous workpiece materials. The 0.04-inch projection from the edge supports clearance in confined bore geometries. It is used on CNC turning centers where a qualified shank seat and appropriate toolholder are already in place.

Key Features

• Solid carbide construction for rigidity and dimensional stability in internal threading
• AlTiN+ coating for extended tool life and performance in high-temperature cutting conditions
• 60-degree profile angle covers unified inch thread forms across a broad TPI range
• 18 to 56 TPI range supports coarse through fine thread pitches in a single tool
• 0.25-inch shank diameter fits standard CNC lathe toolholders for internal boring
• No coolant-through design - external coolant or dry cutting applies

Compatibility

Designed for use in CNC lathe and turning center toolholders accepting a 0.25-inch shank for internal single point threading applications.

Installation Notes

Installation is performed by qualified CNC machinists following standard toolholding procedures for single point threading inserts and boring bar-style shanks. Ensure the machine spindle is fully stopped and the turret is in a safe index position before seating or removing the tool. Confirm shank clamp torque per the toolholder manufacturer specification and verify tool projection before running a threading cycle. Follow applicable shop safety protocols and machine-builder guidelines for tool offset entry and thread cycle parameters.
