Somta Long Series Drill - HSS-E Parabolic Flute - 6.6mm

Meet the Somta Long Series Drill - HSS-E Parabolic Flute - 6.6mm, a purpose-built solution for precision deep-hole drilling where accuracy, durability, and repeatable results matter. This long-length drill is engineered to reach through thicker workpieces without sacrificing rigidity or hole quality, making it a reliable workhorse for challenging metalworking tasks.

• Deep-hole capability with uncompromising rigidity: The extended flute length delivers consistent hole geometry from start to finish, enabling clean, true holes even in thick materials.
• HSS-E construction for tough environments: High-Speed Steel with cobalt (HSS-E) delivers superior heat resistance and wear resistance, helping maintain sharp cutting edges under demanding cutting speeds and feeds.
• Parabolic flute design for efficient chip evacuation: The parabolic flute geometry channels chips away from the cutting edge, reducing cutting forces and heat buildup to extend tool life and minimize clogging.
• Precise, clean hole quality: Sharp cutting edges and optimized flute geometry produce accurate hole diameters with smooth finishes, reducing the need for secondary deburring.
• Reliable performance across common metals: Designed to perform consistently in steel, cast iron, and alloyed materials, making it a versatile option for general engineering, fabrication, and maintenance tasks.
• User-friendly for machine and chuck setups: The robust shank and balanced geometry ensure smooth operation in standard drill chucks and spindle attachments, with reduced runout for better hole concentricity.

This drill is ideal for engineers, machinists, and maintenance technicians who routinely encounter thick workpieces or deep holes. When you need to bore accurately through substantial material without frequent tool changes, the Somta Long Series Drill delivers dependable performance and long tool life.

Practical tips for best results: use appropriate cutting fluid to optimize heat dissipation, start with a centered pilot if necessary to reduce wander, and maintain a steady feed to prevent bit deflection. Let the flute work do the cooling and chip clearance, and avoid applying lateral pressure that can dull the cutting edges. Regularly inspect the point and flute for wear to ensure consistently clean holes over time.
