Radius Boring Bars

  • Designed to produce consistent internal radii and transitions

  • Stable cutting geometry helps reduce chatter and protect surface finish

  • Improves repeatability on contoured features compared to manual finishing

  • Optional AlTiN+ coating extends tool life

Radius Boring Bars are engineered to machine internal radii with repeatable form control and a smooth finish without hand blending.
