Europa Tools Long Series Drill - HSS CO8 - Straw Coated - 10.5mm

The Europa Tools Long Series Drill in 10.5 mm delivers extended reach and dependable performance for deep-hole drilling across a range of materials. Built with high-speed steel enhanced by cobalt (HSS CO8) and finished with a straw-coated surface, this drill bit is engineered to cut smoothly, stay sharp longer, and resist heat during demanding jobs.

Why the Long Series matters — the extended flute and flute length provide access to deeper holes and intricate workpieces where standard bits can’t reach. Whether you’re tackling recesses in automotive components, drilling through thick metal plates, or preparing layout holes in fabrication projects, this long-series design helps you work faster with fewer bit changes.

Premium construction for tougher jobs — HSS CO8 combines high-speed steel with 8% cobalt, delivering superior hot-hardness and edge retention. That means cleaner cuts, reduced work-hardening, and longer tool life when drilling through tough alloys, stainless steel, or non-ferrous metals. The straw-coated finish isn’t just cosmetic; it enhances wear resistance and helps the bit withstand extended drilling sessions without dulling as quickly as standard HSS bits.

Key features at a glance

• Diameter: 10.5 mm
• Material: HSS CO8 for elevated heat resistance and durability
• Finish: Straw-coated for improved wear resistance and smoother cutting
• Long-series design for extended reach and versatility in deep-hole drilling
• Suitable for a wide range of metals and tougher materials

Practical use cases — Ideal for workshops, fabrication shops, and maintenance tasks where deep holes are required or where access is limited. Use it for drilling through steel plates, aluminum assemblies, brass fittings, and other common engineering materials. The combination of cobalt-enhanced steel and a robust finish makes it a reliable workhorse for repeated drilling in demanding environments.

Tips for best results — to maximize life and performance, start with a precise pilot hole if needed, use steady feeds rather than full pushes, and apply light cutting fluid or oil to reduce heat. Let the bit do the work; avoid forcing it through hard sections, which can cause premature wear or chatter. After use, clean away chips and store in a dry environment to preserve the coating and edge integrity.
