Milling and grinding media are designed for ball milling and the grinding of bulk powder or granular materials into finer powder forms. Ceramic bead, hard metal shot, carbide balls, and other ballshaped media are used. The hardness of the powder or bulk material to grind determines the selection of the media material.

Groove or slot milling. Groove or slot milling is an operation in which side and face milling is often preferred to end milling. Slots or grooves can be short or long, closed or open, straight or nonstraight, deep or shallow, wide or narrow. Tool selection is normally determined by the width and depth of the groove and, to some extent, length.

There are various comminution methods for mineral processing. Crushing and grinding are common comminution processes, where the main aim is the liberation and reduction of the size of the ore. Crushing techniques make use of cone, jaw or gyroscopic crushers, yet grinding techniques are more often performed by milling, such as SAG or ball milling.

Associate Editor, Modern Machine Shop. On its surface, grinding seems simple: a machine takes a rotating tool (usually a wheel) with abrasive grains and applies it to a workpiece's surface to remove material. Each grain is its own miniature cutting tool, and as grains dull, they tear from the tool and make new, sharp grains prominent.

End mill tools are millcutting tools that cut in all directions, making them quite different from drill tools that cut only axially. Manufacturers use the end mill for tool steel cutting and other milling processes, including plunging, reaming, slotting, drilling, face milling, profile milling, etc. There are common types of end mill cutters.
