- Non-regrinding carbide end mills or end mills should be used for face milling. In general milling, try to use the second pass for processing. It is best to use the end mill for rough milling in the first pass, and move continuously along the surface of the workpiece. The width of each pass is recommended to be 60%--75% of the tool diameter.
- End mills and end mills with carbide inserts are mainly used to process bosses, grooves and box mouth surfaces.
- Ball knives and round knives (also known as round nose knives) are often used to process curved surfaces and beveled contours. The ball cutter is mostly used for semi-finishing and finishing. Round knives inlaid with carbide tools are mostly used for roughing.
