Description
The Somta Stub Drill in the HSS-E Parabolic Flute TiAlN Coated (163-X) series is a high-performance drill bit designed for demanding drilling applications. Made from HSS-E, this drill combines exceptional hardness, heat resistance, and durability with a TiAlN coating that enhances wear resistance and lubricity for tougher materials. The parabolic flute design ensures efficient chip evacuation, helping to keep cutting temperatures in check and extend tool life.
With its stub length, this drill delivers outstanding rigidity and stability during workpiece penetration, resulting in precise, starting holes and clean finished cuts even in challenging metals. The combination of robust construction and advanced coating makes it a reliable choice for both professional workshops and serious hobbyist projects.
- Rigid stub geometry for precise starts: The shorter, fixed-length body minimizes flex and chatter, delivering clean, accurate hole starts even in tougher materials.
- TiAlN-coated HSS-E for long life: The TiAlN coating boosts wear resistance and high-temperature performance, helping the drill stay sharper longer in demanding drilling tasks.
- Parabolic flute for rapid chip evacuation: The parabolic flute moves chips away quickly, reduces cutting heat, and supports consistent, smooth drilling across depths.
This drill is designed to deliver dependable performance across a range of metalworking tasks, from precise pilot holes to deeper holes in steel and other hard metals. By combining rigidity, durable coating, and efficient chip control, it supports faster setup, less rework, and consistently quality results project after project.
