Specifications:
The document provides detailed specifications for a series of cutting tools designed for direct cutting of cemented carbide. Key parameters include ball radius (R), effective length (ℓ1), length of cut (ℓ), neck diameter (d2), shank diameter (d), and overall length (L). The tools are available in two types, Type I and Type II, with varying dimensions and retail prices.

Material and Coating:
The tools are made from regular grain carbide and feature a newly-developed diamond coating that enhances sticking force. This combination provides a balance between cutting edge strength and sharpness.

Ordering Information:
When ordering, specify the DCMB code along with the ball radius and effective length. The neck profile has a reference interference angle of 12°, and actual measurements are recommended to avoid interference with the work material.

Recommended Milling Conditions:
The document includes a table of recommended milling conditions for different ball radii, including spindle speed, feed rate, and depth of cut. It emphasizes the importance of following these conditions to prevent tool breakage and coating peeling.

Technical Data:
An example of technical data is provided, detailing spindle speed, feed rate, depth of cut, and machining time for finishing operations on cemented carbide with a hardness of 89HRA. The use of oil mist as a coolant is recommended, and surface roughness achieved ranges from 0.51μm to 1.04μm.
