Europa Tools Long Series Drill - HSS CO8 - Straw Coated - 4mm

Europa Tools Long Series Drill – HSS CO8, Straw Coated, 4mm The Europa Tools Long Series Drill is built for professionals who demand precision, durability, and extended reach in every hole. Crafted from high-speed steel with cobalt (HSS CO8), this 4mm drill bit delivers steady, efficient cutting even in tougher materials, helping you achieve clean holes with fewer passes and less heat buildup.

Why HSS CO8 matters for long drill bits

• Enhanced hot-hardness: CO8 cobalt content boosts resilience when drilling harder alloys, reducing blunting and extending tool life.
• Durable cutting edges: optimized edge retention means you’ll reach deeper into metals and composites with fewer re-sharpenings.
• Consistent performance across materials: whether drilling stainless steel, aluminum, or tough plastics, the drill maintains stable feeds and smooth cuts.

Straw coated finish — less friction, longer life

• Straw-coated surface lowers friction between the flute walls and the workpiece, helping to evacuate chips more efficiently.
• Improved wear resistance translates to longer tool life in demanding tasks and repetitive drilling cycles.
• Visual distinction plus practical protection against minor corrosion in storage and transport.

Long series design for extended reach

• Extended flute length enables deep-hole drilling and access to recessed or hard-to-reach areas without re-clamping.
• Rigid geometry minimizes deflection, helping you maintain accuracy when starting holes on challenging workpieces.
• Ideal for fabrication, maintenance, and in-field drilling where standard-length bits fall short.

4mm diameter versatility

• Perfect for precise pilot holes, deburring, and aligning components in metalwork, woodworking, and plastic assemblies.
• Pairs well with a range of drilling speeds and feeds tailored to metals and non-ferrous materials, enabling clean starts and minimal wander.

Practical tips for best results

• Use light, steady feeds and avoid excessive pressure to keep the cutting edge cool and reduce built-up edge.
• When drilling metals, apply a suitable cutting fluid or light oil to improve chip evacuation and extend tool life.
• Start with a light pilot hole if working with hard materials to guide the bit and prevent wandering.
• Keep the drill sharp and store in a dry location to preserve the straw-coated surface and overall performance.

Designed for professionals and serious enthusiasts alike, the Europa Tools Long Series Drill – HSS CO8, Straw Coated – 4mm combines extended reach, durable construction, and a finish that sustains performance under demanding drilling tasks. If you’re tackling stainless steel, alloyed metals, hardwood, or tough plastics, this 4mm drill bit helps you punch through with confidence and precision.
