Double ended boring bars with HSS
I own one of those double ended boring bars which use HSS. Not really sure how they are suppose to be used. But guessing
- The 90-degree end is for threading Operations
- The 45-degree end is for turning operations
- Most HSS bits are ground for standard threading operations.
- Big advantage over inserts is reduced chatter. Inserts bear forces at the furthest point on the tool.
Is my understanding correct?
Thanks in advance, Tom
