Guide to Cutting Speeds and Feeds: Definition, Selection ...
On a rotary tool like a drill bit or milling cutter, cutting speed is equal to how fast its periphery spins relative to the stock clamped to the worktable, it's the same with the tools used on lathes, except their cutting speeds are measured by how fast the rotary material moves past the edge of the turning tool.
Endmill Selection Guide - Conical Tool Company
Applying an abundance of coolant doesn't necessarily mean that the coolant is being used appropriately. Administering multiple streams to select areas of the end mill, generally positioned at the point where the cutting tool rotates into the workpiece, has been shown to be more effective than simply dousing the end mill or workpiece with coolant.
