Europa Tools Stub Drill - HSS CO8 Cobalt - 5.55mm

The Europa Tools Stub Drill (820502 series) is a high-performance drill bit crafted from HSS CO8 Cobalt. With a compact stub length and a 5.55 mm diameter, it delivers rigid, precise holes in stainless steel, alloy steel, and cast iron. Ideal for engineers, fabricators, and workshops, this bit provides dependable performance in demanding drilling tasks where accuracy matters.

The cobalt-enhanced HSS construction offers increased hardness and heat resistance, helping the bit stay sharp under tough cutting conditions. The stub-length design boosts rigidity for steady, controlled drilling, while the sharp cutting edges and optimized flute geometry support efficient chip evacuation and reduced clogging—delivering faster, cleaner holes with less effort.

• Stub-length design for rigidity: The shorter flute length minimizes deflection, helping you maintain straight, accurately sized holes in hard materials.
• CO8 cobalt-enhanced hardness: Cobalt alloy increases wear resistance and heat tolerance, extending bit life when drilling stainless steel, alloy steel, or cast iron.
• Efficient chip evacuation and sharp edges: Precision-ground cutting edges and flute geometry improve chip clearance, reduce clogging, and sustain consistent drilling speed and finish.

This 5.55 mm stub drill helps you complete projects faster with repeatable hole quality, fewer reworks, and longer tool life. Its combination of rigidity, durability, and clear chip clearance makes it a reliable choice for production runs, repair work, and on-site tasks alike—so you can work confidently with tough metals and achieve professional results every time.
