Somta Stub Drill - HSS-E Parabolic Flute UnCoated - No.19

The Somta Stub Drill - HSS-E Parabolic Flute UN-COATED, No. 19 is a compact, high-performance drill bit designed for precise, controlled drilling across a wide range of materials. Part of Somta's HSS-E Parabolic Flute UN-COATED family, this tool combines hardness, toughness, and heat resistance in a stub-length form factor that delivers reliable performance in both production and precision work.

Sized for compatibility with standard drill chucks, the No. 19 size fits common fixtures. The HSS-E material provides excellent edge retention and durability, while the uncoated surface keeps the tool simple and robust for everyday use. The parabolic flute geometry promotes fast, clean chip evacuation to minimize clogging and heat build-up, helping you maintain a sharp cutting edge through longer drilling sequences. The stub length enhances rigidity, reducing deflection and producing accurate holes even in challenging materials.

• Parabolic flute for efficient chip evacuation: The parabolic flute geometry moves chips away from the cutting edge quickly, reducing heat buildup and helping maintain a sharp cut through longer drilling cycles.
• Stub length for rigidity and precision: The shorter flute length increases tool rigidity, minimizes deflection, and yields cleaner, more accurate holes in a variety of materials.
• HSS‑E material for durability: High-speed steel with extra toughness provides wear resistance and heat tolerance, enabling reliable performance across a wide material range.

Designed for professionals who value consistent hole quality, reduced rework, and dependable performance across daily tasks—from quick maintenance holes to prototype runs—this drill delivers predictable results with every use. Its robust build and stable cutting action help you complete projects faster and with confidence, whether you’re an engineer, machinist, tradesperson, or hobbyist.
