Introducing the Somta Extra Long Series Drill - HSS-E Parabolic Flute - 6mm x 205mm. Engineered for deep-hole drilling, this drill delivers exceptional reach without compromising hole quality, making it a trusted tool for demanding metalworking projects.

• Extended reach for deep holes: with a true 205 mm length, this drill lets you reach into thick workpieces or internal bores where standard drills can’t access, reducing the need for auxiliary extensions.
• HSS-E construction: High-Speed Steel-Enhanced builds resilience against heat and wear, delivering durable performance and longer tool life under demanding drilling conditions.
• Parabolic flute design: optimized for rapid chip evacuation, this flute geometry minimizes clogging and friction, allowing smoother cutting and cleaner holes even in tough materials.
• Sharp, stable cutting edges: precision-ground edges provide clean entry and accurate hole dimensions, while the flute profile helps maintain stability and reduce drill wandering.
• Consistent performance in metalworking: ideal for deep-hole tasks in a range of metals, offering reliable rigidity and predictable outcomes when precision matters most.
• When to choose it: select this drill for deep-slotting, internal bores, or any application where reach and precision are critical—without sacrificing drilling efficiency.

The Somta Extra Long Series Drill excels in scenarios where depth is non-negotiable and hole quality can’t be sacrificed. Its combination of extended reach, durable HSS-E material, and efficient parabolic flute makes it a standout choice for fabrication shops, automotive repair, mold making, and heavy equipment maintenance—where access is limited and precision is essential.

Tips for best results: start with a light pilot if needed, maintain steady feeds to control heat buildup, and apply appropriate cutting fluid to extend tool life and improve surface finish. Ensure proper workholding to minimize deflection during deep-hole drilling, and routinely inspect flute integrity after extensive use to prevent unexpected breakage.
