Europa Tools Long Series Drill - HSS CO8 - Straw Coated - 4.2mm

Engineered for demanding metalworking tasks, the Europa Tools Long Series Drill in 4.2 mm combines a long-series geometry with cobalt-enriched HSS CO8 and a straw-coated finish to deliver reliable performance where other bits struggle.

Extended reach and precision for challenging holes

The long-series design is built to reach deep into workpieces, through material stacks, or into recessed areas where standard-length drills fall short. The 4.2 mm diameter makes it ideal for precise pilot holes, alignment holes, and finishing holes in metal assemblies, helping you maintain tight tolerances and clean hole quality.

Premium material and coating that last

Crafted from HSS CO8, this drill bit offers superior edge retention and heat tolerance compared with ordinary high-speed steel, enabling dependable cuts across a wide range of metals and alloys. The straw-coated finish not only gives the bit its distinct appearance but also enhances wear resistance, helping you achieve more holes per edge and extend tool life in busy workshop environments.

What makes it stand out

• 4.2 mm drill diameter with long-series design for extended reach
• HSS CO8 composition for durability and heat resistance in metal drilling
• Straw-coated finish to boost wear resistance and long-term performance
• Versatility across a wide range of materials and drilling tasks
• Precise, clean hole quality suitable for pilot holes, alignments, and finishing work

Tips for best results

To maximize performance, clamp your work securely and use a suitable cutting fluid or lubrication when drilling metals. Start at a moderate speed, then adjust based on material hardness and depth. Let the drill do the work—avoid applying excessive force, and back the bit out periodically to clear chips for consistent cuts.
