Description
The Somta Stub Drill in the HSS-E Parabolic Flute TiAlN Coated (163-X) series delivers a high-performance drilling solution for demanding jobs. With a 6.5 mm diameter, this stub drill is built from HSS-E (High-Speed Steel–Enhanced) for exceptional hardness, heat resistance, and durability. The TiAlN coating enhances wear resistance and lubricity, helping the drill stay sharper longer even in tough materials. The parabolic flute design promotes efficient chip evacuation, reducing heat buildup and extending tool life, while the stub length provides excellent rigidity for precise, repeatable holes.
- Stub-length rigidity for precise holes: The shorter, stout geometry minimizes flex during cutting, delivering consistent hole positions and cleaner finishes in demanding materials.
- Parabolic flute for efficient chip evacuation: Fast, smooth chip clearance reduces heat buildup and minimizes clogging, supporting longer tool life and steadier cutting action.
- TiAlN-coated HSS-E for wear and heat resistance: The advanced coating and alloy core resist wear and high temperatures, helping maintain sharpness and extend usable life in tougher drilling tasks.
Designed for engineers, fabricators, and professionals who require reliable, repeatable results, this drill helps streamline workflo w by reducing downtime, preserving hole accuracy, and delivering consistent performance across a range of metals. Whether drilling steel, aluminum, or alloys in workshop or field settings, the Somta Stub Drill offers stability, durability, and confidence with every hole.
