•►The spiral, or rate of twist in the drill, controls the rate of chip removal in a drill.

•►A fast spiral drill is used in high feed rate applications under low spindle speeds, where removal of a large volume of swarf is required.

•►Low spiral drills are used in cutting applications where high cutting speeds are traditionally used, and where the material has a tendency to gall on the drill or otherwise clog the hole, such as aluminum or copper.
