Europa Tools Long Series Drill - HSS CO8 - Straw Coated - 4.1mm

The Europa Tools Long Series Drill in HSS CO8 with a straw-coated finish is built for serious metalworking tasks that demand both reach and reliability. This 4.1 mm drill bit blends extended length with a cobalt-enriched core, delivering crisp, accurate holes in tough materials while maintaining sharpness through demanding cuts.

• Extended reach for deep, hard-to-access holes: the long-series design lets you drill through thick sections and into recessed areas without needing extensions or multiple setups.
• Premium HSS CO8 alloy: 8% cobalt content increases heat resistance and edge retention, so you can pierce tougher alloys and maintain dialog with precision longer than standard high-speed steel bits.
• Straw-coated finish for performance and longevity: the straw coating reduces friction and improves wear resistance, helping the edge stay sharper and the tool cooler during extended drilling sessions.
• Efficient chip evacuation and stable geometry: flute design promotes smooth chip removal, minimizes clogging, and reduces stick‑slip when drilling in metal, wood, or composite materials.
• Precise 4.1 mm diameter: ideal for clean, repeatable pilot holes and accurate final bores, supporting consistent tolerances in fabrication and assembly tasks.

Ideal uses include professional workshops—automotive repair, fabrication shops, and maintenance environments—where deep-hole drilling is a routine requirement. It’s also a reliable choice for serious DIY projects that involve penetrating thick stock or working in constrained spaces where shorter bits fall short.

Why this long-series drill stands out compared with conventional short bits is not just the reach. The combination of HSS CO8’s durability and the straw coating’s heat and wear benefits translates to longer service life, steadier holes, and less rework in demanding materials. When you need a drill that maintains performance from start to finish—through heat, friction, and stubborn substrates—the Europa Tools Long Series Drill delivers.

Practical tips for best results:

• Use a light coolant or cutting oil to further reduce heat buildup on tougher metals.
• Begin with a center punch to prevent walking, then steadily feed to the final 4.1 mm bore.
• Clear chips frequently with short pauses to preserve edge integrity during extended cuts.
• Store clean, dry, and flat to protect the tip geometry and coating between uses.
