Long Series HSSBORDO Long Series Bright HSS Metric
- ANSI B94-11
- 118° split point with 30° helix.
- Split point is self centering and reduces the need for end thrust. Friction at workpiece is reduced.
- 118° point angles are ideal for use in materials such as mild steel and cast iron.
- The 118° point creates easily controlled chips which are wide and thin.
- Bright Finish Twist Drills have no surface treatment and are supplied in the as-ground condition.
- These tools are suitable for general purpose use, particularly for non-ferrous applications.
