	~~Simply put, the Cold Saw cuts materials.~~

	~~More specifically, the Cold Saw rotates a circular blade with sharp teeth to chip away at the material being cut.~~

	The Cold Saw is "cold" because most of the thermal energy generated during the cutting process is transferred to the chips that are cut off, instead of the blade or the remaining material. That said, the Cold Saw needs coolant to be consistently applied to the blade during operation.

	Different material compositions, shapes, dimensions all determine how fast the blade should spin (rotation speed) and how quickly the blade should move into the workpiece (feed rate). If the feed rate is too high, the blade is in danger of jamming and breaking. If the feed rate is too low, the blade's durability will not be maximized.

	~~Cold Saw blades can be resharpened many times!~~

	~~Should the blade move towards the workpiece, or the workpiece move toward the blade, or both?~~
