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

Correct Answer: Right hand spiral fluted reamer

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.
