Meet the Somta Extra Long Series Drill — HSS-E Parabolic Flute, 9.5mm x 410mm. Built for deep-hole precision with unmatched reach, this drill is a reliable workhorse for extended drilling jobs where standard bits simply can’t reach.

Engineered with HSS-E (High-Speed Steel - Enhanced) for exceptional durability and heat resistance, it withstands demanding cutting conditions and heavy workloads. The extra-long 410mm flute length delivers generous reach, enabling clean, accurate holes in long workpieces, fixtures, and recessed areas without compromising stability or alignment.

The parabolic flute design is a standout feature: it fluidly evacuates chips, minimizes clogging, and reduces friction during penetration. This means smoother starts, steadier cutting action, and cooler operation—translating to longer tool life and consistently clean hole diameters.

Key benefits you’ll notice in real-world use:

• Deep-hole capability: Extended reach that simplifies drilling through thick materials or inside assemblies where access is limited.
• Efficient chip evacuation: Parabolic flute sweeps chips away from the cutting edge, lowering heat buildup and maintaining cut quality.
• Sharp, reliable geometry: Precise starts and clean hole finish thanks to optimized cutting edges and flute design.
• Durable, heat-tolerant construction: HSS-E delivers long tool life even under high-speed, high-feed conditions common in heavy-duty drilling.

Ideal applications include deep pilot holes in steel, aluminum, and other non-ferrous materials, as well as challenging long-hole tasks in automotive, aerospace, and fabrication contexts. When you need a drilling solution that combines reach, durability, and reliable hole quality, the Somta Extra Long Series Drill stands out as a trusted choice.
