The type of reamer used for reaming operation in a blind hole, is

A. Straight fluted reamer

B. Left hand spiral fluted reamer

C. Right hand spiral fluted reamer

D. Any one of these

Answer: Option C

Solution(By Examveda Team)

Right hand spiral reamers should be selected for blind holes.
- Additionally a right hand spiral also helps bridge interruptions such as cross-holes or keyways.
- A right hand spiral reamer may cut slightly oversized holes due to the aggressive flute geometry.
- They perform very well in highly ductile materials.
