Somta Long Series Drill - HSS-E Parabolic Flute - 1mm

Precision drilling meets durable, high-performance design with the Somta Long Series Drill. This 1mm HSS-E drill bit is engineered for deep-hole work, delivering reliable accuracy where it matters—through thick materials, recessed features, and tight tolerances. The extended reach of the long-series design means you can tackle through-holes and deep pockets without re-clamping or repositioning, helping you keep your workflow steady and repeatable.

Why this drill stands out

  • HSS-E construction delivers excellent wear resistance and heat tolerance, so you maintain cutting performance even under demanding speeds and materials.
  • Parabolic flute geometry optimizes chip evacuation and reduces cutting forces, minimizing heat buildup and helping extend tool life in challenging drilling jobs.
  • Sharp, stable cutting edges produce clean, precise holes with minimal burrs, enhancing fit and finish for assemblies, fixtures, or prototypes.
  • Long-series reach provides added depth capability for deep holes, blind holes, and hard-to-reach workpieces without compromising rigidity.

Ideal use cases

  • Micro-drilling in electronics enclosures, sensor mounting points, or precision instrumentation where a 1mm hole is required.
  • Deep-hole drilling in metals and alloys where traditional short drills struggle with chip evacuation.
  • Through-holes in thick plates, panels, or molded components where accuracy and hole quality affect assembly alignment.

How to get the best results

  • Secure the workpiece firmly and use a steady feed to minimize deflection, especially at small diameters.
  • Consider using light cutting fluid or coolant on harder materials to reduce heat and extend tool life.
  • Inspect the flute integrity after extended use; replace if cutting performance declines to preserve hole quality.

With the Somta Long Series Drill - HSS-E Parabolic Flute - 1mm, you’re choosing a purpose-built solution for precise, reliable micro-drilling in demanding contexts. Upgrade your toolkit with a drill that pairs depth capability and clean hole quality in a single, durable design.
