Europa Tools Long Series Drill - HSS CO8 - Straw Coated - 5.5mm

The Europa Tools Long Series Drill in 5.5 mm is built for serious metalworking tasks where reach and reliability matter. Crafted from HSS CO8 with a straw-coated finish, this drill bit blends high-performance cutting with durable wear resistance to keep you drilling longer between regrinds. The long series geometry provides extended reach without compromising straightness or rigidity, making it ideal for deep holes and crowded workpieces. This isn’t a one‑trick bit—it’s a versatile tool built to handle a wide range of materials with consistent results.

Key features that set this drill apart

• HSS CO8 alloy (8% cobalt) for improved heat resistance and edge retention when drilling tougher metals, including stainless and high-strength alloys. This composition is a hallmark of premium cobalt-enhanced drill bits.
• Straw-coated finish delivers reduced friction and enhanced wear resistance, helping the drill maintain a sharp cutting edge under demanding conditions. The coating also contributes to smoother chip evacuation during heavy-duty drilling.
• Long series design offers extended reach for deep holes, tight cavities, and through-holes where standard-length bits struggle to reach. This geometry preserves cutting efficiency even as you extend your drilling depth.
• DIN 338-compatible geometry ensures reliable fit in common chucks and consistent hole quality across tasks, a practical advantage when moving between projects or shop setups.
• Broad material compatibility suitable for a variety of metals—from mild steel to tougher alloys and non-ferrous materials—making it a dependable workhorse for fabrication, repair, and maintenance workflows.

Why choose a long-series, cobalt-enhanced drill like this? The combination of 8% cobalt content and a straw finish delivers a balance of toughness and heat tolerance, enabling faster cutting speeds without sacrificing tool life. The extended flute length reduces working length limitations, letting you tackle deeper holes in assemblies, fixtures, and components where space is at a premium. This is a professional-grade bit designed to stay sharp longer, reduce downtime, and improve overall drilling efficiency in metalworking projects.

Practical tips for best results: - Use appropriate drilling speeds and lubrication for the material at hand to maximize coating life and edge retention. - Avoid forcing the bit; let the flute design and cobalt hardness do the work for you. - After heavy use, inspect the cutting edge and re-sharpen as needed to maintain optimal performance. - Store in a clean, dry environment to preserve the straw-coated surface integrity between jobs.
