Learn more about Klarna

The Somta Long Series Drill - HSS-E Parabolic Flute - 3mm is purpose-built for deep-hole drilling where reach and reliability matter most. Crafted for tough materials and demanding applications, this long-length drill bit delivers clean, accurate through-holes in thick workpieces without sacrificing rigidity or finish.
Why this drill stands out:
- HSS-E durability: High-Speed Steel with enhanced alloying provides exceptional hardness and heat resistance, allowing sustained cutting performance under tougher drilling conditions.
- Parabolic flute design (110): Optimizes chip evacuation and lowers cutting forces, reducing heat buildup and helping extend tool life even on longer drill strokes.
- Long-series reach: Specifically engineered for deep holes, giving you the ability to drill where shorter bits can’t reach while maintaining straightness and control.
- Precise, clean holes: Sharp cutting edges and efficient flute geometry produce accurate hole diameters with minimal burrs when used with proper feeds and lubrication.
- Versatile material compatibility: Effective across metal substrates—from aluminum to stainless and alloy steels—with appropriate speeds and coolant to maximize performance.
Practical use scenarios include fabricating thick plates, inserting fasteners through heavy sections, or creating long, true through-holes for fixtures and jigs. For best results, entry should be steady and straight, a light pilot helps establish alignment, and flood coolant or cutting fluid keeps heat and chips in check to protect both tool and workpiece.
Who should reach for the Somta Long Series Drill? machinists, metal fabricators, and serious DIYers who routinely work with thick materials and require dependable long-reach drilling. This 3mm HSS-E parabolic-flute drill optimizes survival under demanding workloads, delivering consistent holes and extended tool life compared with standard-length bits.
