Somta Long Series Drill - HSS-E Parabolic Flute - 2.8mm

Somta Long Series Drill - HSS-E Parabolic Flute - 2.8mm is a precision-engineered drill bit built for demanding deep-hole work. Designed to tackle thick workpieces with confidence, this long-length bit maintains straightness and stability where standard drills struggle, delivering reliable holes every time.

Why choose this drill for deep-hole projects?

• Long-length design for deep reach: When you need to pierce through thick materials or reach into recessed areas, the extended flute length provides the reach you require without compromising rigidity.
• HSS-E construction for durability: Made from High-Speed Steel with added alloying elements, it offers superior wear resistance and heat tolerance, so you can drill longer between tool changes.
• Parabolic flute for efficient chip evacuation: The parabolic geometry channels chips away from the cutting edge, reduces cutting forces, and minimizes clogging—helping to maintain cutting efficiency on long drills.
• Sharp cutting edges for clean holes: Precision-ground edges deliver accurate hole diameters with minimal burrs, even in tougher materials, reducing the need for follow-up finishing.
• Lower friction, cooler operation: The flute design and geometry work together to reduce friction and heat buildup, extending tool life and maintaining hole quality over time.
• Consistent results in demanding environments: Ideal for machine shops, fabrication, and workshops that require dependable deep-hole performance for precision workpieces.

Practical usage tips to get the most from your 2.8mm Somta Long Series Drill:

• Clamp the workpiece securely to prevent deflection and ensure true hole alignment during deep drilling.
• Match spindle speed and feed rate to the material and drill length to optimize chip evacuation and reduce heat buildup.
• Use appropriate lubrication or cooling as you would with any extended-length drill to protect the cutting edges and maintain hole accuracy.
• Begin with a shallow pilot or center mark to guide the bit and minimize wandering, then progressively feed deeper as the hole opens.

Designed for professionals who demand precision, durability, and consistency, the Somta Long Series Drill - HSS-E Parabolic Flute - 2.8mm elevates deep-hole drilling from routine to reliable. Whether you’re fabricating a component, repairing a chassis, or executing precision drilling in challenging materials, this drill bit delivers clean holes, longer tool life, and real value in every job.
