Overview: The document provides technical specifications and guidelines for circular thread milling using advanced tools and techniques. It highlights the capabilities and features of the tools, including left rotation, threading depth, and internal coolant usage.

Specifications: The tools are designed for left rotation (counterclockwise) and can achieve threading up to 3xD1. Internal coolant is recommended for optimal chip evacuation, with a minimum pressure of 20 bar. The tools are made from micro-grain solid carbide and feature cutting edge finishing, advanced internal coolant systems, and optimal PVD wear protection.

Thread Milling Cycle: The document lists various models (e.g., ZBGF6065VS, ZBGF6067VS) with specific dimensions and parameters such as diameter (D1), pitch (P), and lengths (l11, l2, l3). These parameters are crucial for selecting the appropriate tool for specific threading tasks.

Technology and Threading: The document includes detailed tables with cutting speeds, feed rates, and material group classifications. It provides guidelines for different materials, including steels, stainless steels, cast iron, titanium, nickel alloys, copper, aluminum, plastics, and precious metals. Each material group has specific hardness, tensile strength, and recommended cutting speeds and feed rates.

Key Recommendations: For best results, use internal coolant with a minimum pressure of 20 bar. Select the appropriate tool model based on the material and threading requirements. Follow the specified cutting speeds and feed rates for different materials to ensure optimal performance and tool longevity.
