The Europa Tools Stub Drill, 21.5 mm, from the 820502 series, is a high-quality drill bit crafted from HSS CO8 cobalt. Designed for precision drilling in metalworking projects, it excels where edge retention and heat resistance matter, including stainless steel, alloy steel, and cast iron. Its stub-length geometry adds rigidity, delivering stable, straight holes even in tougher materials.

Sharp cutting edges and an optimized flute design ensure efficient chip evacuation, helping maintain drilling speed while reducing the risk of chip clogging for cleaner, more reliable results.

• Rigid stub geometry for accurate holes: The shorter length increases rigidity and stability, minimizing wandering and delivering consistent hole placement in hard metals.
• HSS CO8 cobalt construction: Enhanced hardness and heat resistance extend tool life when drilling demanding materials like stainless steel and alloy steels.
• Efficient chip evacuation and sharp edges: Flutes move chips away quickly, reducing heat buildup and enabling smoother, faster drilling with less clogging.

With the Europa Tools 21.5 mm stub drill, you gain reliable performance, longer tool life, and predictable results across a range of tough metals. It supports faster workflows, fewer re-drills, and higher-quality holes, making it a dependable choice for professional shops and serious hobbyists alike.
