Which statement correctly describes the rose reamer?

Which statement correctly describes the rose reamer?

• A. It is generally used for rough reaming
• B. It is generally used for finishing reaming
• C. It is used for drilling holes
• D. It is used for threading operations

Answer: (A)

Roughing out a hole quickly is what a rose reamer is designed for. It has multiple cutting edges arranged around the head, which lets it remove material faster than a finishing reamer. This makes it ideal for taking a drilled hole toward its final size in fewer passes, before any finish work. Because the goal is material removal and quick sizing rather than a mirror-smooth bore, it’s used for rough reaming. It isn’t used for drilling, which creates the hole, nor for threading operations, which use taps, dies, or thread milling. If a smoother finish and tighter tolerance are needed, finishing reaming would follow roughing.
