Europa Tools Long Series Drill - HSS CO8 - Straw Coated - 5.7mm

Meet the Europa Tools Long Series Drill — a high-performance HSS CO8 cobalt drill bit with a distinctive straw coating. Designed for professional metalworking tasks, this 5.7 mm drill combines extended reach with durable cutting edges to handle deeper holes and challenging materials with confidence.

• Extended reach: the long-series design provides extra length for deep pockets, through-holes, and workpieces that resist easy access, reducing the need to swap bits mid-task.
• HSS CO8 composition: an 8% cobalt content delivers superior heat resistance and enhanced wear life when drilling hard metals, stainless steel, and alloyed steels, helping to maintain sharpness under demanding cycles.
• Straw coating: the straw finish reduces friction, supports smoother chip evacuation, and contributes to longer tool life in continuous drilling applications.
• Precision geometry: carefully engineered flute and rake geometry deliver clean holes with minimal wandering, even at higher feeds, making it reliable for precise machining workflows.
• Versatile sizing: the 5.7 mm diameter is well-suited for precise pilot holes, mid-size metalworking tasks, and as a dependable workhorse in both shop and hobby setups.

This long-series drill shines when you’re drilling tougher materials or working in tight access areas where standard-length bits struggle. The cobalt-rich HSS, combined with the straw coating, provides a practical balance of durability and performance that helps you push through metals like stainless steel and other hard alloys without frequent bit changes.

Who benefits most: machinists, fabricators, technicians, and ambitious DIYers who need reliable long-reach performance for metalworking projects, from automotive brackets to fabrications that demand through-holes with consistent hole quality.

Care and tips: use appropriate speeds and feeds for the material, maintain sharp edges, and consider light lubrication to optimize cutting efficiency and reduce heat buildup. With proper use, HSS-Co8 bits can be resharpened and reused to extend tool life, delivering consistent results over many drilling sessions.

In practice, the Europa Tools Long Series Drill stands out by delivering dependable depth capability, cobalt-enhanced durability, and a coating that reduces friction during aggressive drilling tasks — all in a single, easy-to-use 5.7 mm bit. For projects that push past the limits of ordinary HSS, this is a thoughtful, capable choice.
