Europa Tools Long Series Drill - HSS CO8 - Straw Coated - 7.4mm

The Europa Tools Long Series Drill in HSS CO8 with Straw Coated finish is built for demanding metalworking tasks where reach and reliability matter. The long-series geometry delivers extended access for deep holes in a variety of metals, reducing the need to reposition or stack tools mid‑project.

• Extended reach you can trust. The long-series design makes it easier to pierce through thick sections, workpieces with tight cavities, or components with recessed features, delivering consistent hole quality from start to finish.
• Premium HSS CO8 core. Crafted from cobalt-containing HSS (8% cobalt), this drill bit is engineered for higher thermal tolerance and sustained cutting performance when drilling hard metals like stainless steel, alloy steels, and cast iron. This reliability is supported by industry references on HSS-Co8 materials and their thermal capabilities.
• Straw-coated finish for durability. The distinctive straw-colored coating provides an additional barrier against wear and helps manage heat buildup during extended drilling sessions, contributing to a longer tool life in tough metals.
• Precision geometry for clean holes. Ground to tight tolerances, the flute and tip geometry work together to reduce wandering, improve chip evacuation, and produce smooth, accurate holes with less required feed pressure.
• Versatile 7.4 mm diameter. A balanced choice for fast material removal and strong hole integrity across a wide range of projects—from fabrication and maintenance to automotive and machinery applications.

Who benefits most: metalworkers, machinists, and technicians who regularly drill deep or through challenging materials will appreciate the long reach and the dependable cutting performance of this HSS CO8 drill. It excels in stainless steel, chromoly, and other alloyed steels, making it a go-to choice for sustained drilling tasks in shop environments or on maintenance jobs where downtime is costly.

Why choose this over standard HSS bits: the combination of an 8% cobalt composition and a straw-coated finish delivers superior heat resistance and wear life compared with conventional HSS, helping you maintain sharpness longer and achieve consistent hole quality under higher cutting speeds and heavier feeds. This makes it especially effective for tougher metals and thicker workpieces.

Pro tips for best results: - Use appropriate cutting fluid or lightweight lubrication when drilling stainless steel to reduce friction and heat. - Start with a steady, moderate feed and avoid aggressive plunging to maintain the drill’s edge integrity. - Clear chips regularly (peck drilling) on deep holes to prevent clogging and binding. - Align workpiece securely to minimize deflection and maximize straight, true holes.

Equip your workshop with the Europa Tools Long Series Drill in HSS CO8 Straw Coated, 7.4 mm, and tackle deep, demanding metal drilling tasks with confidence and precision.
