Learn more about Klarna
The Somta Extra Long Series Drill - HSS-E Parabolic Flute, 11 mm x 280 mm, is built for deep-hole drilling where reach and reliability truly matter. Crafted from HSS-E (high-speed steel with cobalt), this drill combines durability and heat resistance to stand up to demanding, extended drilling sessions without sacrificing hole quality.
- Unmatched reach for deep holes. At 280 mm overall length, this drill is designed to access recessed or through-holes in thick workpieces without needing to reposition your setup.
- Efficient chip evacuation. The parabolic flute geometry channels chips away from the cutting edge, reducing clogging and helping maintain smooth cutting action during long bores.
- Durable, heat-resistant construction. HSS-E blends cobalt into the steel for improved wear resistance and temperature tolerance, extending tool life in steel, cast iron, and other tough materials.
- Precise, clean hole quality. Sharp cutting edges and optimized flute design deliver accurate diameters with minimal deflection, even in challenging substrates.
- Versatile for a range of deep-bore projects. Ideal for automotive, aerospace, mold making, and other applications where a single pass must achieve depth without compromising accuracy.
Why this matters in real work: when you’re drilling deep into thick components or navigating complex assemblies, an extra-long drill like this one minimizes setup changes, speeds up production, and reduces the risk of wandering or chipped edges. The parabolic flute and cobalt-enhanced HSS working together translate to dependable performance from the first hole to the last.
Designed by Somta, a seasoned name in precision drilling tools, this 11 mm x 280 mm drill is a purpose-built solution for professionals who demand long reach, reliable chip control, and consistent hole quality in demanding materials.
