Europa Tools Long Series Drill - HSS CO8 - Straw Coated - 6.5mm

Precision meets endurance in the Europa Tools Long Series Drill – HSS CO8, Straw Coated, 6.5mm. This drill bit is purpose-built for demanding metalworking tasks, delivering consistent hole quality from the first cut to the deepest reach.

The drill is crafted from premium HSS CO8, a cobalt-enriched high-speed steel that excels under high heat and heavy cutting. This composition provides superior edge retention and toughness when drilling through harder metals, reducing the need for frequent re-sharpening and helping you complete multi-step projects with fewer tool changes.

Straw-coated finish adds both form and function. The heat-tinted oxide layer lowers friction between the flute walls and chips, improving wear resistance and helping maintain a cooler cutting edge during extended drilling sessions. The result is smoother chip evacuation, less measureable wander, and longer tool life even in tougher materials.

The long series design is the standout feature for reach and versatility. With extended flute length, you gain deeper access into joints, pockets, and through-holes where shorter bits struggle. This makes it ideal for tasks like deep-wall drilling in steel, stainless steel, cast iron, and aluminum, as well as applications where precise hole depth control matters.

• Deep-hole capability with stable, straight holes thanks to the long flute geometry.
• Exceptional edge retention in hard metals due to cobalt-enhanced HSS and wear-resistant coating.
• Efficient chip evacuation reduces clogging and heat buildup for cleaner cuts.
• Reduced tool wear translates to longer intervals between replacements in demanding workflows.
• Quick, reliable integration into standard drill chucks for fast tool changes on busy benches.

Designed for professionals and serious DIYers, this 6.5mm drill bit is especially well-suited for fabrication shops, automotive work, and metal fabrication projects where deep holes and consistent diameters are critical. If you frequently tackle stainless steel, alloy steels, or cast iron and you need reliable performance from a single bit, the Europa Tools Long Series Drill is built to deliver.

Practical tips for top performance: use appropriate lubrication to minimize heat, start with a light, steady feed, and avoid excessive force which can cause wandering or edge chipping. Keep the drill sharp and clean, and store it in a dry environment to preserve the straw-coated finish and cutting edge for longer tool life.
