Somta Stub Drill - HSS-E Parabolic Flute TiAlN COATED - 3.9mm

The Somta Stub Drill (3.9 mm diameter) from the HSS-E Parabolic Flute TiAlN Coated series is a high-performance drill bit designed for demanding metalworking tasks. It’s built for engineers, fabricators, hobbyists, and service professionals who need reliable holes with repeatable accuracy in tougher materials.

With an HSS‑E substrate and a TiAlN coating, this drill delivers exceptional hardness, heat resistance, and wear life. The stub length provides outstanding rigidity for stable cutting, while the parabolic flute design promotes fast chip evacuation to minimize heat buildup and guide the drill toward clean, precise holes.

• Rigid Stub Design for Precision: The shorter, stiffer body minimizes deflection and maintains hole size accuracy under load, even in tougher metals.
• TiAlN-coated HSS‑E for Durability: TiAlN coating boosts wear resistance and high-temperature stability, extending tool life in demanding materials like alloy steels and stainless.
• Parabolic Flute for Efficient Chip Evacuation: Parabolic flutes clear chips quickly, reduce heat buildup, and support higher cutting speeds for smoother, more consistent drilling.

By choosing this drill, you invest in dependable performance across a range of metals and applications. The combination of rigid stub geometry, wear‑resistant TiAlN coating, and efficient chip evacuation helps you finish jobs faster with higher hole quality, fewer reworks, and less downtime. It’s a trusted, long‑lasting choice for fabrication, maintenance, and precision projects—delivering repeatable results project after project.
