Europa Tools Long Series Drill - HSS CO8 - Straw Coated - 7.7mm

Europa Tools Long Series Drill - HSS CO8 - Straw Coated - 7.7mm is built for professionals who demand depth, endurance, and precision in metalworking. This long-series drill combines advanced material science with smart finishing to handle demanding holes in tough metals without sacrificing performance.

• Extended reach for deep holes — the long-series flute geometry opens up access to thick workpieces, internal features, and hard-to-reach surfaces where standard drills struggle.
• HSS CO8 blend (8% cobalt) — engineered for high-temperature drilling, this cobalt-enhanced high-speed steel maintains a sharp edge longer, delivering consistent cutting performance in stainless steel, alloy steels, and other hard metals.
• Straw-coated finish — a purpose-built coating that reduces friction, improves heat resistance, and enhances wear life, helping the drill stay sharper longer under heavy use.
• Precision-cut geometry — engineered lips and flute design promote smooth entry, clean chip formation, and effective swarf evacuation to minimize heat buildup and wandering.
• Exact 7.7 mm diameter — a reliable, precise size suitable for pre-drilling, pilot holes, or finishing passes in metal fabrication, machining, and maintenance tasks.
• Versatile metalworking performer — excels on stainless steel, cast iron, alloy steels, and other challenging materials, making it a dependable addition to any workshop kit.

Use cases include deep-hole drilling in automotive and aerospace components, fabrication of stainless steel frames, and maintenance work where access is limited but precision matters. The Long Series design reduces the need to switch tools mid-project, helping you complete jobs faster with fewer tool changes.

Why this drill stands out — beyond the core 7.7 mm size and long reach, the HSS CO8 composition and straw coating work together to resist heat, maintain sharpness, and extend tool life in tough metals. That means fewer resharpenings, less downtime, and more consistent hole quality across long drilling sessions.

Practical tips for best results:

• Use appropriate coolant or cutting fluid to manage heat, especially when drilling stainless steel or hard alloys.
• Begin with a light, steady feed to establish the hole and prevent wandering; progress to a slightly heavier feed as the bit engages deeper.
• Peck drill to clear chips and prevent chip packing, which can cause bite resistance and overheating.
• Inspect the flute for signs of wear and re-sharpen when you notice a decline in edge performance.
• Store with care in a dry environment to preserve the coating and reduce corrosion risk on the shank and cutting edges.

Designed to perform where standard drills fall short, the Europa Tools Long Series Drill — HSS CO8 with Straw Coated finish — 7.7mm is a reliable choice for serious metalworking tasks that demand depth, durability, and precision in a single tool.
