D90 to 120 m/min
Answer
Correct Answer: 90 to 120 m/min
Explanation
Concept/ApproachBrass is free-cutting and allows relatively high cutting speeds compared with steels for the same tool material. For HSS tools, a common shop range for turning brass is around 90–120 m/min.
NoteActual choice depends on tool geometry, rigidity, coolant, and surface finish requirements.
Final Answer90 to 120 m/min
