The Europa Tools Stub Drill (11.8 mm diameter) from the 820502 series is a high-quality HSS CO8 Cobalt drill bit designed for precision work in tough materials. Suitable for professionals and dedicated hobbyists, it delivers reliable holes with consistent results in stainless steel, alloy steel, and cast iron.

Its stub length provides extra rigidity for straight, accurate drilling, even in hard metals, while the cobalt composition boosts hardness and heat resistance to resist dulling under demanding cutting conditions. The sharp cutting edges and optimized flute design promote efficient chip evacuation, helping you maintain speed and control.

• Stub-length rigidity for precise holes: The shorter profile minimizes tool deflection, delivering straighter, more controlled drilling in challenging materials such as stainless steel, alloy steel, and cast iron.
• HSS CO8 cobalt for hardness and heat resistance: Cobalt-enhanced alloy maintains edge sharpness at higher temperatures, extending tool life and enabling reliable cutting in tough metals.
• Efficient chip evacuation and sharp cutting edges: Optimized flute geometry and sharp edges reduce chip clogging, improve heat dissipation, and sustain drilling speed for consistent results.

With this drill bit, you can achieve clean, accurate holes quickly and reliably, reducing downtime and rework. The robust cobalt-enriched construction supports dependable performance across demanding materials, while the stub geometry offers greater control in tight spaces. This makes it a versatile addition to any workshop, production line, or field service kit.
