Description
The Somta Stub Drill in the HSS-E Parabolic Flute TiAlN Coated line, 7.3 mm diameter, is a high-performance drill bit built for demanding drilling tasks. It combines HSS-E with a TiAlN coating to deliver hardness, heat resistance, and long tool life so you can tackle tough materials with confidence. A stub-length body provides exceptional rigidity and stability, while the parabolic flute design ensures fast, clean chip evacuation. This combination helps maintain precise hole sizes and reduces heat buildup during extended drilling sessions.
- Rigid stub geometry for precise holes: The shorter, stiff body minimizes deflection and chatter, delivering repeatable starts and depth control in challenging materials.
- Parabolic flute for fast chip evacuation: Efficient chip removal reduces heat buildup, lowers the risk of work hardening, and supports smoother cutting and longer tool life.
- TiAlN coating for wear and high-temperature performance: Enhanced wear resistance and lubricity at elevated temperatures help sustain sharpness and reduce tool wear in demanding drilling tasks.
With this drill, you gain reliable performance, improved workflow, and longer service life. The combination of HSS-E core, TiAlN coating, and parabolic flute delivers clean starts, consistent hole quality, and reduced downtime, making it a dependable choice for professionals and serious hobbyists alike.
