Scientific Cutting Tools TT075300A Threading Tool 36-72 Tpi

Product Description

The SCIENTIFIC CUTTING TOOLS TT075300A is a solid carbide single point threading tool designed for internal threading operations on small-diameter bores. It covers a thread range of 36 to 72 TPI with a 60-degree profile angle, making it suitable for unified and metric-style thread forms at fine pitches. The 0.075 inch minimum threading diameter and 0.3 inch cutting depth allow it to reach tight internal features on turned or milled parts. An AlTiN+ coating provides elevated heat resistance and extended tool life in ferrous and hardened materials. Machinists and CNC lathe operators working on precision components will find this tool sized for small-bore threading cycles.

This tool is intended for internal threading on CNC lathes and turning centers where small-bore access is required. The 1/8 inch shank diameter and 1.5 inch overall length suit it to compact toolholders and live tooling setups common in Swiss-type and small-part turning applications. It is appropriate for threading operations in tool steels, stainless alloys, and other materials where an AlTiN+ coating provides a performance advantage at elevated cutting temperatures.

Key Features

• Solid carbide construction for rigidity and wear resistance in demanding threading applications
• AlTiN+ coating for extended tool life in ferrous and hardened workpiece materials
• 60-degree profile angle compatible with unified and similar thread forms
• Covers 36 to 72 TPI range for fine-pitch internal threading
• 0.075 inch minimum threading diameter enables access to very small internal bores
• No coolant-through design - suitable for standard external coolant delivery

Compatibility

Designed as an OEM-style single point threading tool for internal threading operations requiring a 1/8 inch round shank and fine-pitch TPI range on CNC lathes and turning centers.

Installation Notes

This tool is installed and operated by machinists on CNC lathes or turning centers. Secure the 1/8 inch shank firmly in the toolholder to the manufacturer-specified clamping procedure before beginning any threading cycle. Confirm that the machine spindle and all axes are at a safe stop before changing or indexing tooling. Verify tool projection and alignment to the workpiece centerline prior to running the threading program to avoid deflection or thread-form errors.
