Somta Long Series Drill - HSS-E Parabolic Flute - 6mm

Meet the Somta Long Series Drill - HSS-E Parabolic Flute, 6 mm. Built for deep-hole work, this drill delivers reliable through-hole performance with an extended 110 mm length that reaches into thick materials without sacrificing precision or control. The combination of a long reach and robust construction makes it a dependable choice for demanding manufacturing and maintenance tasks.

• Parabolic flute design channels chips away from the cutting edge quickly, reducing cutting forces and preventing chip recutting. The result is smoother drilling, steadier feeds, and cleaner holes even in difficult materials.
• HSS-E (High-Speed Steel‑E) construction provides superior hardness and heat resistance. This means you can maintain sharper edges longer and sustain higher cutting speeds under demanding conditions, extending tool life in tough metals.
• Long-series geometry (110 mm length) is purpose‑built for deep holes. The extended flute and shaft enable you to reach through thick workpieces with precision, minimizing tool deflection and improving hole accuracy.
• Sharp cutting edges and precise flute geometry deliver clean, round holes with minimal burrs. The result is less rework and tighter tolerances in every job.
• Durability in tough applications—designed to withstand the heat and friction of heavy drilling, making it a reliable choice for production environments and on-site repairs.

This 6 mm Somta long drill is ideal for machinists, fabricators, and maintenance professionals who need a dependable solution for deep drilling in steel, alloys, and other demanding materials. It pairs well with peck drilling techniques, appropriate coolant usage, and careful speed/feed settings to maximize flute life and hole quality.

Practical tips for best results:

• Use a compatible cutting fluid to reduce heat buildup and prolong edge life.
• Start with a light pilot bore to establish alignment, then proceed to full-depth drilling with steady feeds.
• Employ a peck drilling approach to clear chips and prevent clogging in long holes.
• Inspect and resharpen as needed by a professional service to maintain optimal cutting performance.

With its combination of long reach, parabolic flute efficiency, and durable HSS-E construction, the Somta Long Series Drill stands out as a practical, high-performance option for challenging drilling tasks where reliability matters most.
