The Europa Tools Stub Drill in the 820502 series is a purpose-built cobalt-enhanced drill bit designed for precision work in demanding metals. Crafted from HSS CO8 cobalt, it delivers improved hardness and heat resistance for reliable drilling through stainless steel, alloy steel, and cast iron. Its 18.75 mm diameter is paired with a compact stub form to maximize rigidity where accuracy matters.

With a stub-length geometry, this drill stays stable under load, helping you achieve clean, accurate holes with minimal wandering. The sharp cutting edges and optimized flute design promote efficient chip evacuation, keeping the bit cooler and reducing the risk of clogging during fast, repeated drilling.

• HSS CO8 cobalt for extended edge life: Cobalt content boosts hardness and heat resistance, allowing you to cut tougher materials with less wear and longer life.
• Stub-length rigidity for accurate holes: Shorter, stiffer geometry minimizes deflection and chatter, delivering consistently positioned holes and better control in hard workpieces.
• Efficient chip evacuation and sharp flute design: Optimized flutes and sharp cutting edges clear chips quickly, reduce buildup, and support faster drilling with cooler operation.

Designed for engineers, technicians, and hobbyists alike, this drill bit helps you complete tasks more efficiently, with reliable performance across stainless steel, alloy steel, and cast iron. The durable construction and precise stub geometry mean fewer reworks and longer tool life, making it a dependable choice for demanding fabrication and maintenance projects.
