Somta Long Series Drill - HSS-E Parabolic Flute - 2.4mm

The Somta Long Series Drill - HSS-E Parabolic Flute - 2.4mm is built for precision work where holes go deep and staying power matters. Crafted from high-performance HSS-E (high-speed steel with enhanced cobalt), this drill combines toughness with heat resistance to cut cleanly through metals that demand reliability over long cycles. It’s the kind of drill you reach for when you need a consistently accurate starting hole and steady performance in demanding fabrication environments.

• Parabolic flute design dramatically improves chip evacuation and reduces cutting forces. That means smoother drilling, less heat buildup, and extended tool life in tougher materials.
• HSS-E (HSS-Co) construction delivers superior wear resistance and heat tolerance, making the drill ideal for extended use in challenging metals.
• Long-series, straight shank geometry is purpose-built for deep-hole work, enabling deeper penetration without frequent tool changes. The long form pairs with a straight shank for stable alignment in a variety of drill chucks.
• Precise 2.4mm diameter provides clean, accurate entry and consistent hole size for projects that demand tight tolerances. This small-diameter option is well-suited to intricate work on thin sections and precision components.
• 110° point for clean starts and reliable performance across steel, aluminum, and non-ferrous materials. The combination of point geometry and parabolic flute helps maintain control from the first cut to the final exit.

Ideal for engineers, machinists, and fabricators tackling deep-hole drilling in thick workpieces, the Somta Long Series Drill delivers consistent, high-quality holes with minimal wandering. Use it in steel, aluminum, or other metals where chip removal and heat management are critical to surface finish and tool life. For best results, maintain steady feeds and speeds appropriate for HSS-E tools, apply light lubrication or cutting fluid to reduce friction, and periodically withdraw the bit to clear chips when drilling deep profiles.

Designed to outperform standard drills in demanding settings, this 2.4mm Somta long-series drill combines a robust core with an optimized flute profile to minimize heat and maximize uptime—so you can complete precision drilling tasks faster and with greater confidence.
