Europa Tools Long Series Drill - HSS CO8 - Straw Coated - 9.9mm

The Europa Tools Long Series Drill is built for professionals who push the limits of depth and precision in metalworking. With a 9.9 mm diameter and a true long-series design, this drill bit delivers extended reach without compromising rigidity, making it ideal for deep holes in tight spaces and through thick materials.

Why this long-reaching drill stands out

• Premium HSS CO8 construction combines high-speed steel with cobalt enhancements for improved heat resistance and wear life, giving you reliable performance across a range of metals—from stainless steels to alloyed steels.
• Straw coated finish reduces friction and helps minimize built-up edge, promoting smoother starts and cleaner holes while extending tool life.
• Extended reach without sacrifice the long-series geometry provides the depth you need for through-holes and blind-hole work in parts with limited access.
• Precision-ground for consistency sharp flutes and a stable cutting edge deliver straight, true holes with reduced wandering, even in challenging workpieces.
• Durable shank and flute design engineered to withstand repeated tightening, high feed rates, and demanding drilling cycles common in professional shops.

Ideal use cases

• Deep-hole drilling in stainless steel, alloy steels, and other harder metals where standard drills struggle to maintain accuracy.
• Fabrication and machining tasks that require reaching into recesses, pockets, or fixtures where space is tight.
• Automotive and aerospace components where consistent hole size and clean finishes matter for performance and assembly.

How to get the best results

• Use a sharp, properly sized drill for the material at hand and maintain a steady, moderate feed rate to avoid overheating.
• Apply cutting fluid or lubrication to reduce heat buildup and extend tool life, especially in stainless or alloy steels.
• Keep pecking cycles gentle—lift and clear chips regularly to prevent clogging and ensure a clean hole exit.
• Ensure the workpiece is securely clamped to minimize deflection and maintain hole accuracy throughout the drilling process.

Durability and longevity

The combination of HSS CO8 and the straw-coated finish is designed to endure tough drilling cycles. This drill bit resists wear in demanding materials, maintains its edge longer, and delivers repeatable performance across multiple holes, reducing downtime and the need for frequent tool changes.
