Somta Stub Drill - HSS-E Parabolic Flute UnCoated - No.4

The Somta Stub Drill No.4 from the HSS-E Parabolic Flute UnCoated series is a compact drill bit designed for precise hole‑making across a variety of materials. Its stub‑length geometry delivers added rigidity and stability, helping you drill straight holes with minimal drift. Paired with durable HSS‑E alloy and a parabolic flute, it promotes efficient chip evacuation and consistent performance in metalworking, plastics, and other common workpieces.

• Parabolic flute design for efficient chip evacuation: The curved flute geometry moves chips away quickly, reduces heat buildup, and lowers the risk of clogging, resulting in cleaner holes and longer tool life.
• Stub-length rigidity for precision: Shorter, more rigid geometry minimizes deflection and improves hole straightness, especially in metalworking and precision tasks.
• HSS‑E alloy with an uncoated finish: The high‑strength HSS‑E material delivers excellent hardness and wear resistance for reliable drilling across a wide range of materials, without the need for coatings.

This drill bit helps you work faster and with greater confidence. The combination of stub‑length rigidity, parabolic chip evacuation, and durable HSS‑E performance provides consistent hole quality, fewer reworks, and smoother setups in everyday projects—from fabrication and maintenance to DIY builds. Use it with standard drilling equipment to achieve precise, clean holes with minimal wandering and good heat management.
