Drill Bits/SetsBORDO Long Series Black HSS Fractional
- ANSI B94-11
- 118° chisel point with 30° helix.
- Chisel point is suitable for general purpose drilling.
- Black Finish Twist Drills (also called blue finish) achieve their distinctive colour by steam tempering, a thermal process resulting in a porous tool coating.
- This surface helps to keep lubricant on the tool, particularly important on the cutting edges, thus reducing friction and cold welding. The result is increased tool life.
- Black finish tools are generally recommended for ferrous applications where the oxide layer aids chip flow and heat dissipation.

Drill Bits/SetsBORDO Long Series Bright HSS Fractional
- 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.
