Europa Tools Long Series Drill - HSS CO8 - Straw Coated - 3.5mm

The Europa Tools Long Series Drill is built for professionals who demand depth, durability, and consistent precision. At 3.5 mm in diameter, this drill bit is the go-to choice when you need a reliable start and a clean, true bore in tighter tolerances and deeper holes.

Long series design meets real-world drilling needs. The extended flute length provides extra reach for through-holes, deep pockets, and work in recessed areas where standard bits simply can’t reach. Whether you’re fabricating metal enclosures, servicing automotive panels, or assembling machinery, this drill delivers where precision and reach matter most.

HSS CO8 construction puts cobalt-enriched high-speed steel at the core of this bit, delivering enhanced hardness and heat resistance. The result is improved edge retention and longer tool life, so you can drill more holes with fewer bit changes, even in tougher metallic materials.

The straw-coated finish isn’t just about looks. This finish reduces friction, boosts wear resistance, and promotes steady performance under demanding cutting conditions. Combined with optimized geometry, it helps chips clear smoothly, minimize heat buildup, and keep the cut consistent from start to finish.

Key benefits you’ll notice

• Extended reach for deep, through-hole drilling without repositioning workpieces
• Durable HSS CO8 core that maintains sharpness under demanding metalworking tasks
• Straw-coated surface for reduced wear and longer bit life
• Precision-ground tip for accurate starts and minimal wandering
• Efficient chip evacuation thanks to flute geometry, keeping boreholes clean

Ideal for professionals and seasoned hobbyists who work with metal components, assemblies, and fixtures where depth and reliability trump quick, shallow cuts. The Europa Tools Long Series Drill offers measurable advantages over standard-length bits: fewer tool changes, less downtime, and consistently better hole quality in challenging materials.

Usage tips: start with a light pilot drill if needed, secure the workpiece firmly, and apply steady pressure with appropriate lubrication or cutting fluid for metal drilling. Align your drill perpendicular to the work surface to prevent wandering, and select a slower speed for tougher metals to minimize heat buildup.
