Somta Long Series Drill - HSS-E Parabolic Flute - 10mm

Meet the Somta Long Series Drill - HSS-E Parabolic Flute - 10mm, a purpose-built solution for deep-hole drilling where precision and endurance matter. Designed to cut cleanly through thick materials, it delivers reliable performance when every hole counts.

Why this drill stands out for deep-hole work

The Long Series profile gives you the reach you need without sacrificing rigidity, enabling true, straight holes in challenging workpieces. The parabolic flute design actively improves chip evacuation, dramatically reducing chip buildup that can cause binding or wandering. Coupled with a sharpened cutting edge, this drill maintains a clean cut even after extended use in high-temperature conditions.

Key features and benefits

• HSS-E construction — cobalt-enhanced high-speed steel for superior heat resistance and wear life, helping the bit stay sharp under demanding drilling.
• Parabolic flute geometry — optimized chip clearance and reduced cutting forces, which translates to smoother starts and less friction-driven heat.
• 110-degree point geometry — precise centering on initial contact, minimizing walk and ensuring accurate hole placement from the first cut.
• Long series design — extended flute length crafted for through-holes in thick or layered materials, reducing the need to stop and re-position.
• Sharp, durable edges — designed to produce clean edges and tight tolerances, with less burr formation on exit.
• Compatibility — fits standard drill chucks and common drilling setups found in metalworking shops, fabrication facilities, and workshop environments.

Ideal use cases

Best suited for metalworking tasks where deep access is required, such as drilling through steel plates, cast iron sections, and other thick metallic workpieces. Ideal for automotive repair, industrial fabrication, tooling, and aerospace components where hole accuracy and tool life matter as much as speed.

Practical tips for best results

• Use appropriate coolant or light lubrication to manage heat and extend tool life during long flights.
• Peck drilling in longer holes to flush chips and prevent clogging; pause to clear chips as needed.
• Maintain a steady feed rate and avoid excessive lateral pressure to preserve the sharp cutting edges.
• Inspect tips and flutes regularly; a sharp edge and clean flutes are key to consistent hole quality.

Equip your toolkit with the Somta Long Series Drill - HSS-E Parabolic Flute - 10mm to achieve dependable, high-quality deep-hole drilling results, even in demanding materials and tight tolerances.
