Somta Long Series Drill - HSS-E Parabolic Flute - 2mm

The Somta Long Series Drill, crafted in HSS-E with a parabolic flute, is designed for serious deep-hole tasks where thickness and precision matter. At a compact 2 mm diameter, this drill bites through material with a combination of strength, heat resistance, and exceptional chip management that keeps holes true and matter-of-factly clean.

Why this 2 mm Somta drill stands out

• Extended reach for deep holes: The long-series geometry enables penetrating thick sections without losing rigidity or accuracy, reducing the need to rework or re-drill.
• HSS-E construction for durability: High-Speed Steel with enhanced heat resistance stands up to demanding drilling tasks, helping maintain sharpness and hole tolerances under load.
• Parabolic flute for superior chip evacuation: The curved flute path channels chips away from the cutting edge, minimizes friction, and lowers cutting forces for smoother, faster drilling.
• Precise, clean results: Sharp cutting edges and optimized flute geometry produce consistent hole diameters with minimal burr formation, even in challenging materials.
• Heat management that extends tool life: Efficient chip removal and reduced heat buildup mean less wear and longer intervals between replacements in repetitive production use.

Ideal use cases

Designed for deep-hole drilling in metalworking environments where through-thickness accuracy matters. Use this 2 mm drill for thin-to-thick metallic sections, jigs and fixtures, service panels, and applications that require through-holes with reliable symmetry and smooth finishes. It’s particularly advantageous when standard short drills struggle to reach into recesses or when consistent chip removal is critical to maintaining hole quality over long pecking cycles.

Practical guidance for best results

• Pair with appropriate feeds and speeds for the material you’re working with to maximize life and keep holes true.
• Maintain steady drilling pressure and use a light coolant or lubrication to control heat during extended drilling sessions.
• Allow ample clearance behind the workpiece to accommodate long drill travel and chip evacuation.
• Inspect the drill tip regularly; a sharp edge is essential for clean entry and consistent hole diameter.

In environments where deep-hole precision and reliability are non-negotiable, the Somta Long Series Drill - HSS-E Parabolic Flute - 2 mm delivers predictable performance, reduced tool wear, and consistent hole quality that you can trust—even on demanding materials and thicknesses.
