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
- 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.

Colour Band
BORDO Green Band HSS-Co TiN Carbon Steel Drilling
- Bordo Metric Green Band HSS-Co TiN Coated Twist Drills for Carbon Steel.
- DIN338
- 130° split point with two helical flutes with 33 degrees of helix angle.
- The machinability of different carbon steels is as varied as their properties. Soft-tough construction steels place a unique set of demands on the tools.
- The Green Band Series of drills and taps have been developed specifically for this range of steels.
- For machining materials with Hardness < 250 HB : Tensile Strength <900 N/mm2.

Cobalt HSS-Co5
BORDO Cobalt HSS-Co5 Jobber Drill Fractional Set
- 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.
