Bordo 2mm HSS Cobalt TiAlN Coated Blue Band Jobber Drill Bit 2050

Bordo HSS-Co cobalt drill bits drill stainless steel, high-tensile alloys, and hard materials where standard HSS would dull rapidly. The HSS Cobalt TiAlN Coated Blue Band Jobber Drill Bit 2050 is part of Bordo's comprehensive Australian cutting tool range — trusted by engineers, tradespeople, and machinists across industry and manufacturing.

Where this product is used

HSS-Co (cobalt) drill bits contain 5–8% cobalt alloyed into the steel — they resist the heat generated when drilling stainless steel and high-tensile alloys.

• Drilling hard and work-hardening steels including stainless steel and high-tensile alloys
• Aerospace, food processing, and marine fabrication drilling
• Engineering production where drill bit life on difficult materials is critical

Key specifications

Selecting the right option

HSS-Co (cobalt) drills run at lower speeds than standard HSS — cutting speed should be reduced by 25–30% on stainless steel to prevent work hardening. Jobber length is the standard for most applications; short (stub) series suits rigid setups where deflection is a concern.
