• 8 Gauge Bright HSS Twist
  • Bordo Wire Gauge Quick Silver M2-HSS Twist Drills.
  • 118º Split Point (crankshaft point).
  • Split point is self centering and reduces the need for end thrust. Friction at workpiece is reduced.
  • 118º point angles are ideal for use in materials such as mild steel and cast iron.
  • The 118º 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.
  • Gauge size drill calculations are generally made utilising a reference book or table.
  • For example, to drill a hole which is 10 thou (thousandth of an inch = .001) bigger than a 1/8? bolt, the user must first work out that 1/8? is 125 thou, so the required hole size is 135 thou. Using a reference table establishes that you would need a number 29.
  • Number drill bit gauge sizes are analogous to, but different from, American wire gauge.
  • Number gauge is most commonly used from size 80 (the smallest) to size 1 (the largest) followed by letter gauge size A (the smallest) to size Z (the largest).
  • Number gauge is actually defined down to size 97, but these smallest sizes are very rarely used.
