Black Finish HSSBORDO Black Finish HSS Jobber Drill Fractional
- Bordo Black Knight M2-HSS Twist Drills.
- ANSI B94-11
- 118° Split Point (crankshaft point)
- 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.
- 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.

Cobalt HSS-Co5BORDO Cobalt HSS-Co5 Jobber Drill Fractional
- Bordo Fractional Cobalt Tough HSS-Co5 Twist Drills.
- ANSI B94-11
- 135° Split Point (crankshaft point).
- Split point is self centering and the short distance from the drill axis to the outer corners results in faster penetration, reducing the need for end thrust.
- The 135° point should be used to cut harder steel materials especially in deep hole applications.
- In these situations it will produce thicker chips minimising work hardening of the cavity.
- Faster penetration reduces abrasion and friction along the cutting edges.
- Cobalt HSS Twist drills are extremely hard and provide superior performance and increased tool life especially in stainless steel and high tensile steel.
- Bronze Finish (gold oxide) surface treatment. The metallic brown coloured low temperature temper treatment is normally only used on cobalt tools for identification purposes.

Delta Point Bright Finish HSSBORDO Delta Point Bright Finish HSS Metric
- Bordo Metric Delta Point M2-HSS Twist Drills.
- DIN338
- Delta Point drills have a multi-faceted cutting tip.
- Rather than try and modify existing point types, or tweak the grind angles, Delta Point tip design required a revolutionary re-think of drill tip function.
- The overall length of the cutting edge significantly exceeds that of conventional drills.
- This means more edge doing the cutting and the results are simply extraordinary.
- Drilling times for a range of split point and Delta Point drills consistently showed that Delta Point bits were twice as fast in mild steel.
- During independent lifetime testing Delta point drill bits averaged 609 holes in 20mm mild steel, ten times more holes than split point drills.
- DRILLS FASTER LASTS LONGER.
- 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.

Bright Finish HSS
BORDO Wire Gauge Bright Finish HSS Jobber Drill
- Bordo Wire Gauge Quick Silver M2-HSS Twist Drills.
- 118° Standard Chisel Point
- Chisel point is ideal for general purpose drilling.
- 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.
- 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.
