Introducing the Somta Extra Long Series Drill – HSS-E Parabolic Flute, 15.5mm x 320mm. Engineered for deep-hole drilling, this drill combines exceptional reach with dependable performance to tackle challenging workpieces from start to finish.
- Extra-long reach for deep holes: at 320mm in length, this drill bit accesses interior bores, long through-holes, and recessed cavities without requiring multiple setups.
- HSS-E durability: High-Speed Steel-E construction delivers superior heat resistance and wear resistance, extending tool life in demanding materials.
- Parabolic flute for efficient chip evacuation: the parabolic flute design accelerates chip flow, minimizes clogging, and helps maintain steady cutting in deep drilling applications.
- Sharp cutting edges for clean holes: precision geometry yields accurate hole diameters with smooth entrances and exits, reducing the need for rework.
- Reduced friction and heat buildup: flute geometry lowers operating temperature and friction, supporting consistent performance across long drilling passes.
- Designed for deep-hole tasks across metals: ideal for manufacturing, maintenance, and repair work where precise deep bores are essential, including long shafts, bushings, and structural components.
When your project demands a reliable drill that reaches where others can’t and still delivers true-to-size holes with minimal fuss, the Somta Extra Long Series Drill stands out. Add it to your toolkit and experience confident deep-hole drilling with a tool built to endure.
