About this item:
  • 21/64 HSS Long Series Drill
  • 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.
