Europa Tools Long Series Drill - HSS CO8 - Straw Coated - 4.9mm

Meet the Europa Tools Long Series Drill - HSS CO8 - Straw Coated - 4.9mm. This high-performance drill bit is engineered for precision, durability, and extended reach in demanding metalworking tasks, delivering reliable results when every hole matters.

Extended reach for deep drilling

The Long Series geometry is purpose-built to reach deeper into workpieces without repositioning or sacrificing rigidity. Whether you’re drilling through thick steel members, fabricating machinery bases, or threading holes in hard-to-access areas, this bit maintains a straight, clean cut and steady chip evacuation. The extended length minimizes tool changes and keeps your workflow efficient in confined spaces.

Co8 cobalt-enhanced durability

Crafted from HSS CO8, this drill features 8% cobalt content, delivering superior hot hardness and wear resistance. The enhanced alloy maintains edge sharpness under higher temperatures, which translates into longer life and more consistent performance when drilling hard or alloyed steels. In practical terms, you’ll experience fewer dulls and fewer replacements on tough jobs.

Straw-coated finish for friction and wear reduction

The straw-coated finish isn’t just a visual cue—it’s an oxide treatment that helps reduce friction and heat during cutting, contributing to cooler operation and extended tool life. Straw finishes are commonly used on cobalt-containing HSS drills to signal their wear-resistant properties and to support durability in demanding drilling scenarios.

4.9 mm diameter for versatile drilling sequences

With a precise 4.9 mm diameter, this Europa Tools drill is ideal for pilot holes, stepped drilling sequences, and holes in metalwork where precise sizing matters. The combination of long reach, cobalt-strength, and the straw finish helps ensure smooth cutting and controlled hole quality across a range of common metals, including mild steel, stainless steel, aluminum, and cast iron.

Practical usage tips

For best results, use a moderate cutting speed and, when working with harder metals, a light cutting fluid to manage heat and extend edge life. Maintain steady feeds, withdraw the bit to clear chips on deep holes, and resharpen when the cutting edge shows signs of dulling to maximize the tool’s life. These practices help you extract maximum performance from HSS CO8 long-series bits like this one.
