Product catalog summary
Specifications:
The document provides detailed specifications for various cutting tools, including parameters such as diameter, effective length, length of cut, neck diameter, neck taper angle, shank diameter, overall length, flute count, and retail price. The tools are designed for machining hard brittle materials like carbide and ceramics, featuring a high rigidity due to an increased core size and a high-adherence diamond coating.

Procedures and Recommendations:
The document outlines recommended milling conditions for different work materials such as carbide, alumina, and heat-resistant glass. It specifies spindle speed, feed rate, and depth of cut for each tool size. It emphasizes the importance of following these conditions to prevent tool breakage and coating flake, minimizing tool rotation run-out, and understanding machine characteristics for small cutting depths. The use of water-insoluble cutting oil is recommended.

Technical Data and Examples:
Two technical examples are provided:
1. Tool size φ0.3 used on carbide with a hardness of 92.5HRA, achieving a surface roughness of Rz 0.12μm over a cutting length of 39.2m in 8 hours and 30 minutes using water-insoluble cutting oil.
2. Tool size φ1 used on 96% alumina, achieving a surface roughness of Rz 1μm over a cutting length of 91.3m in 17 hours and 50 minutes using water-soluble oil.

Safety and Ordering Information:
Safety precautions include adhering to recommended milling conditions and minimizing tool rotation run-out. For ordering, the document specifies indicating the tool diameter and effective length, with the neck taper angle provided as a reference value.
