Notched point is a variation on the standard chisel point, providing faster starting and reduced drill wander.
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.
Bordo reduced shank HSS drills are ground and then a black finish is achieved by steam tempering, a thermal process resulting in a porous tool coating.
This surface aids chip flow and heat dissipation.
The drill is then ground a second time to achieve a bright finish on the shank and cutting edges.
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.

One piece solid core design is significantly more durable than the conventional two piece design that utilises a hex sleeve on a standard round drill bit.
Specifically engineered for use in impact drivers these bits are also fully compatible with conventional rotary drills.
135° split point delivers a precision start and prevents bit wander for fast, accurate holes.
Premium quality M2 HSS ensures extreme performance and long bit life.
1/4″ hex shank facilitates fast tool loading in cordless impact drivers and quick change adaptors.
