Meet the Somta Long Series Drill — HSS-E Parabolic Flute — 7.5mm, a purpose-built solution for challenging deep-hole tasks where precision, durability, and reliability matter most. This isn’t just a drill bit; it’s a performance upgrade for thick materials and demanding machining environments.

Why this drill stands out

  • Long length for deep holes — designed to reach and bore accurately through substantial material thickness without sacrificing rigidity or control.
  • HSS-E construction — combines high-speed steel with an enhanced alloy mix for superior wear resistance and heat tolerance, reducing downtime and frequent bit changes in tough applications.
  • Parabolic flute geometry — optimized for fast chip evacuation and lower cutting forces, which means smoother drilling, less binding, and cleaner, more precise holes.
  • Sharp cutting edges — engineered to produce clean terminations with minimal burrs, even when drilling through hard or layered substrates.
  • Reduced heat buildup — efficient flute design minimizes friction, protecting the edge and extending tool life in high-temperature drilling scenarios.

Ideal use cases

  • Deep-hole drilling in thick metal plates and structural components
  • Fabrication, mold making, and automotive applications where precision through depth is essential
  • Any task requiring consistent hole quality, reduced deflection, and longer tool life under demanding conditions

How it helps your workflow

  • Increase productivity with fewer tool changes thanks to the drill’s deep-drilling capability and robust construction.
  • Improve hole quality—flawless roundness and clean entrance/exit edges reduce finishing work and assembly fit issues.
  • Cut wasted time from heat-related tool wear. The HSS-E alloy resists softening and maintains sharpness longer in demanding materials.

To get the most from your Somta Long Series Drill, pair it with proper peck drilling techniques, moderate feeds, and adequate lubrication. Let the parabolic flute carry away chips steadily, maintaining stable cutting conditions and prolonging both tool life and workpiece integrity.
