Somta Long Series Drill - HSS-E Parabolic Flute - 7.7mm

Meet the Somta Long Series Drill – HSS-E Parabolic Flute – 7.7mm, a purpose-built solution for deep-hole drilling where reach and reliability matter. This drill bit is designed to tackle thick workpieces with unwavering precision, turning challenging bores into clean, repeatable holes.

• Long-length design for deep-hole access: The extended flute length delivers the reach needed for internal bores, pockets, and hard-to-reach areas without sacrificing rigidity.
• HSS-E alloy for durability and heat resistance: An enhanced high-speed steel composition stands up to elevated cutting temperatures, reducing wear during extended drilling sessions.
• Parabolic flute geometry for superior chip evacuation: Efficient chip removal keeps the cut clear, lowers heat buildup, and maintains consistent hole quality throughout the operation.
• Reduced cutting forces and lower friction: The parabolic design and sharp cutting edges minimize resistance, improving hole diameter accuracy and extending tool life.
• Clean, precise holes in demanding materials: Optimized for metals such as steel and cast iron, as well as common alloys encountered in fabrication and maintenance work.
• Versatile for industrial and workshop use: Ideal for production runs or single-repair jobs where deep drilling capability is essential.

In practice, this 7.7mm HSS-E parabolic-flute long drill excels when you need consistent, high-quality holes in thick components, from automotive housings to machine frames. Use appropriate speeds and feeds for your material, and apply light lubrication to minimize wear and preserve hole straightness. The Somta Long Series Drill is more than a bit—it’s a dependable tool that helps you finish projects faster with fewer interruptions.
