Description
The Somta Stub Drill - HSS-E Parabolic Flute TiAlN Coated, 4.6 mm diameter, is a high‑performance drill bit built for demanding metalworking tasks. Designed for engineers, fabricators, tradespeople, and serious hobbyists, it delivers precise, repeatable holes in tougher materials thanks to its rugged HSS‑E core, protective TiAlN coating, parabolic flute for efficient chip evacuation, and a stub length that provides maximum rigidity.
- Parabolic flute for rapid chip evacuation: The parabolic geometry moves chips away from the cutting edge quickly, reducing heat build‑up and helping maintain sharpness for longer tool life.
- TiAlN-coated HSS‑E core: The coating boosts wear resistance and high‑temperature performance, delivering longer tool life and cleaner holes in demanding cuts.
- Stub-length geometry for rigidity: Shorter, stiffer profile minimizes deflection and yields clean, accurate holes even in challenging materials.
This combination of durable material, protective coating, and rigid geometry translates into faster production, longer service life, and fewer interruptions from dull tools. It supports consistent hole quality and reliable performance across a range of metals, making it a dependable choice for professional shops and serious hobbyists alike.
