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.

Colour Band
BORDO Yellow Band HSS Aluminium Drilling
- Bordo Metric Yellow Band HSS Twist Drills for Aluminium and its alloys.
- DIN338
- 130° web thinned point with two helical flutes with 35 degrees of helix angle.
- The alloying elements which achieve varying Aluminium Alloys have an effect on the machining properties of these materials.
- This generally creates a difficult long chip formation and material which has tendencies to stick to the tool, placing a unique set of demands on tooling. Yellow Band Series contends with these difficulties.
- For machining materials with Hardness < 200 HB : Tensile Strength <700 N/mm2.
