Meet the Somta Long Series Drill - HSS-E Parabolic Flute, 3.6mm—a precision-engineered tool built for deep-hole success in demanding materials. This drill is designed to reach through thick sections with confidence, delivering accurate bore sizes from the first breakthrough.

Why professionals choose this long-series drill
- HSS-E construction provides reliable hardness and heat resistance during extended drilling, keeping sharp edges for longer than standard high-speed steel bits.
- Parabolic flute geometry excels at chip evacuation, pulling debris away from the cutting edge and reducing cutting forces for smoother starts and steadier penetration.
- The long flute and extended flute length stabilizes deep-hole drilling, minimizing deflection and vibration in thick materials.
- Sharp, precise cutting edges produce clean bore holes with minimal burr, enabling tighter fits and better assembly results.
- Friction and heat buildup are actively managed through the flute design, extending tool life and reducing the need for frequent changes in harsh drilling environments.
- Versatile for drilling through tough metals and thick sections in fabrication, automotive, and general engineering projects.
How to get the best results
Maintain a steady feed and avoid aggressive plunging. Use appropriate cutting fluid or coolant to manage heat, and release swarf regularly to prevent chip buildup. Start with a conservative speed, then increase as the material yields, listening for signs of rubbing or smoke and backing off if needed. With proper technique, this drill delivers consistent hole quality, straightness, and a clean bore edge even when drilling deep holes.
Who benefits most
Engineers, machinists, hobbyists and small workshops tackling deep-hole tasks in metal fabrication will appreciate the balance of reach, durability and precision. Ideal for through-holes in thicker workpieces where standard-length bits struggle to maintain accuracy or experience chips packing in the flute.
