- Long Reach (Aircraft) Drill
- Long Reach Drills are suitable for all general purpose drilling where extra reach is required.
- Long Reach Drills are not designed to drill deep holes.
- Maximum hole depth must be less than the flute length (FL) of the drill.
- Deep hole drilling requires the use of a Bordo Long Series Drill, Bordo Extra Deep Hole Drill or Bordo Auger Bit depending on the material being drilled.
- 135° Split Point (crankshaft point)
- Split point is self centering reducing the need for end thrust.
- The 135° point provides superior performance when drilling harder steel materials.
- In most situations it will produce thicker chips minimising work hardening of the cavity.
- Faster penetration reduces abrasion and friction along the cutting edges.
- Black Finish 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.

Long Series HSSBORDO 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.
