Somta Extra Long Series Drill - HSS-E Parabolic Flute - 14.5mm x 310mm is engineered for deep-hole drilling with unmatched reach and consistent precision. Built to cut cleanly through tough materials, this drill thrives where standard bits fall short.

Key features that translate into real-world results:

  • 14.5 mm diameter with a 310 mm extra-long flute provides extended reach for deep holes in thick workpieces or assemblies where access is limited.
  • HSS-E construction combines high-speed steel with enhanced alloying for superior heat resistance and longer tool life under demanding drilling conditions.
  • Parabolic flute geometry moves chips efficiently away from the cutting edge, reducing clogging, minimizing heat buildup, and improving hole quality.
  • Sharp cutting edges and precise pitch deliver clean, true holes with minimal burrs in steel, aluminum, and cast iron.

Practical use cases:

  • Deep pocket and blind-hole drilling in engine blocks, cylinder heads, and mold tooling.
  • Through-holes in thick plates where access is restricted and a standard-length bit cannot reach.
  • Fabrication and repair work that requires extended reach without compromising accuracy.

Why this matters for you:

  • Faster work cycles: better chip evacuation means fewer interruptions to clear chips and re-position bits.
  • Longer tool life: the durable HSS-E composition resists overheating and wear, saving you from frequent tool changes.
  • Consistent hole quality: parabolic flutes maintain stable cutting action across the life of the drill.

Usage tips for best results:

  • Use appropriate cutting fluid or lubrication for metal drilling to extend life and improve finish.
  • Start with a light pilot hole if needed, and adopt a steady peck drilling approach to clear chips.
  • Secure the workpiece and use a rigid setup to prevent deflection during deep drilling.
  • Inspect the bit for signs of wear and replace when cutting edges become dull to maintain hole accuracy.

Who should consider the Somta Extra Long Series Drill?

  • Machine shops and fabrication shops performing deep-hole tasks on steel, aluminum, or cast iron.
  • Hobbyists and makers tackling long-reach drilling projects that demand precision and reliability.
  • Maintenance professionals conducting repairs in tight spaces where standard bits can't reach.

With the Somta Extra Long Series Drill, you gain confidence in every deep-hole job—from initial pilot to finished bore—thanks to a combination of reach, durability, and cutting efficiency that few standard bits can match.
