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.
