Europa Tools Long Series Drill - HSS CO8 - Straw Coated - 4.7mm

Introducing the Europa Tools Long Series Drill — a precision tool built for serious metalworking tasks. This drill bit is made from HSS CO8, an 8% cobalt alloy, designed to resist heat and retain a sharp edge under demanding drilling conditions. The straw coated finish adds an extra layer of durability and smoother cutting action, helping you push through tougher materials with confidence. The 4.7 mm diameter makes it a versatile choice for a wide range of projects, from fine metalwork to mid-grade fabrication.

Long reach, high performance

The defining feature of the Long Series is extended reach. With a longer flute length than standard bits, it helps you reach deep holes and confined spaces without sacrificing rigidity. Whether you're drilling through thick stainless steel, aluminum, or cast iron, this drill bit maintains axial alignment for clean, true holes. The spiral geometry is optimized to carry chips away efficiently, reducing heat buildup and staying true to its edge under load.

Key benefits

• 8% cobalt resilience means better heat resistance and extended tool life when working with stainless steel and other hard alloys.
• Straw coated finish minimizes friction and wear, contributing to longer bit life and smoother cutting action in a range of materials.
• Deep-hole capability thanks to the long-series design — ideal for reach-in drilling, pocket holes, and through-holes in metalwork.
• Precise 4.7 mm diameter for accurate hole sizing in mechanical assemblies, jigs, and fixtures.
• Versatile material compatibility suitable for steel, stainless steel, cast iron, aluminum, brass, and other nonferrous metals when paired with proper speed and lubrication.
• Drill-friendly maintenance – easy to re-sharpen and compatible with standard drill chucks found in workshops and home garages.

Use cases and best practices

Designed for professionals and serious DIYers, this drill bit shines in scenarios such as:

• Automotive repair and maintenance where access is tight and holes must be precise.
• Fabrication and metalworking projects involving stainless steel panels, brackets, or frames.
• Repairs on machinery where through-holes require deep reach without tilting the bit.
• Prototype builds and workshop tasks that demand consistent hole quality and extended bit life.

Practical tips for optimal results: set a moderate drilling speed appropriate for metal, apply a light cutting fluid or oil to reduce heat, keep the drill aligned with the workpiece, and withdraw the bit periodically to clear chips. For especially hard materials, start with a shallow pilot and incrementally increase depth to prevent wandering or premature wear.

In short, the Europa Tools Long Series Drill in HSS CO8 with a straw coated finish delivers dependable performance, long tool life, and the reach you need for demanding metalworking tasks. It’s a reliable choice for technicians who value precision, durability, and efficiency in every hole they drill.
