Description
The Somta Stub Drill, part of the HSS‑E Parabolic Flute TiAlN Coated (163‑X) series, is a high‑performance drill bit designed for demanding drilling tasks. With a 9.5 mm diameter, it combines a tough HSS‑E core with a TiAlN coating to deliver hard‑wearing performance, heat resistance, and long tool life. The stub length provides excellent rigidity for precise, stable drilling, while the parabolic flute promotes fast chip evacuation and cooler operation.
- HSS‑E core for rigidity and reliability: Built from high‑speed steel with enhanced alloying, this drill delivers consistent performance under demanding conditions and across multiple holes, helping maintain accuracy and reducing rework.
- TiAlN coating for wear and heat resistance: The titanium aluminum nitride coating reduces wear, lowers friction, and extends tool life even at higher operating temperatures, improving overall drilling productivity.
- Parabolic flute and stub geometry for chip evacuation and accuracy: The parabolic flute design facilitates rapid chip removal, while the stub length adds rigidity to minimize deflection and enhance hole quality and perpendicularity.
This combination helps you produce clean, accurate holes consistently, reduces downtime from heat and chip buildup, and supports faster workflows across production or maintenance tasks. The Somta Stub Drill is a dependable choice for professionals who value reliability, repeatability, and precise results.
