The Somta Long Series Drill - HSS-E Parabolic Flute - 2.9mm is built for serious metalworking, delivering precise, deep-hole performance where it counts. Designed for extended reach and dependable durability, this drill bit pairs a long-series profile with advanced materials to tackle thick workpieces with confidence.

Why this drill stands out

  • Long-series reach enables deeper holes and through-holes in thick materials without losing alignment or rigidity.
  • HSS-E construction delivers outstanding durability and heat resistance, maintaining cutting sharpness in demanding drilling tasks.
  • Parabolic flute geometry optimizes chip evacuation, reduces cutting forces, and minimizes heat build-up for smoother, faster drilling.
  • Sharp cutting edges provide clean, round holes with minimal burrs, even in tougher metals.
  • Efficient heat management and reduced friction within the flute contribute to longer tool life and more consistent hole dimensions.

Ideal use cases

Perfect for metalworkers, fabricators, and precision machinists who need reliable deep-hole capabilities. Use the 2.9 mm Somta Long Series Drill for through-holes in steel, alloy steels, and aluminum blocks, or any application where a small-diameter drill must reach substantial depths without wandering. Suitable for drill presses, milling machines, and CNC setups where consistent hole depth and straightness are essential.

How to get the best results

Secure the workpiece firmly and begin with a light pilot to establish a true center. Apply a coolant or cutting oil to manage heat, and use a measured feed to let the parabolic flutes carry chips away efficiently. For deep holes, employ a peck drilling technique—advance, pause to clear chips, then advance again—to maintain hole quality and prevent chip pack-out. Always withdraw the bit smoothly to avoid binding as the hole reaches depth.

Care and longevity

Keep the cutting edges sharp and inspect the flute for wear after heavy use. Store in a dry environment to prevent corrosion, and replace when cutting performance drops or the hole diameter deviates. With careful use and routine maintenance, this HSS-E parabolic flute drill remains a trusted choice for accurate, repeatable deep-hole drilling.
