1/8" Long Reach (Aircraft) Drill

About this item:

• 1/8" Long Reach (Aircraft) Drill
• 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.
