In order to reduce friction between a work piece and a cutting site ______ is used.

• A. Cutting fluid
• B. Lubricant
• C. Oil
• D. Coolant

Answer: (A)

Reducing friction at the interface where the tool meets the workpiece is achieved with cutting fluid. This fluid forms a lubricating film that lowers friction and wear between tool and workpiece. It also helps carry away heat and chips, which keeps temperatures down and protects tool life and surface finish. While a lubricant or oil focuses mainly on lubrication and a coolant on cooling, cutting fluid combines both lubrication and cooling (and chip removal), making it the most effective choice for reducing friction at the cutting interface.
