What are the boring tools?
The Different Types of Boring Tools
- Solid boring bars. Typically made of carbide for finishing or heavy metal for roughing, solid boring bars have dense structures that make for a more stable cut as axial force is applied.
- Damping bars.
- Rough boring heads.
- Fine boring heads.
- Twin cutter boring heads.
- Digital boring heads.
