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 non-straight, deep or shallow, wide or narrow. Tool selection is normally determined by the width and depth of the groove and, to some extent, length.

Insert-based cutters may include one or more rows of inserts and may produce a simultaneous face-milling operation. Slot milling is used for producing a slot or channel in the workpiece. There are two primary types of slot milling cutters: disk mills and end mills. Disk mills can be high-speed steel, brazed carbide, and indexable-insert-based.
