Bright Finish HSSBORDO Wire Gauge Bright Finish HSS Jobber Drill Set
- Bordo Wire Gauge Quick Silver M2-HSS Twist Drills.
- 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.
- 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.

Black Finish HSSBORDO Black HSS Jobber Drill Metric Set
- DIN338
- 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.
