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.

Delta Point Bright Finish HSS
BORDO Delta Point Bright Finish HSS Metric Sets
- 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.
