Somta Long Series Drill - HSS-E Parabolic Flute - 3.8mm

Somta Long Series Drill - HSS-E Parabolic Flute - 3.8mm is purpose-built for precision deep-hole drilling in demanding metals. Its extended reach and robust construction let you punch clean, accurate holes through thick workpieces without sacrificing rigidity or control. The long-series design is ideal for through-holes, deep pockets, or hard-to-reach panels where standard drills struggle.

• HSS-E construction for durability under heat: High-Speed Steel-E adds enhanced heat resistance and wear protection, so the drill maintains sharpness and accuracy through tough drilling tasks and high-speed cutting.
• Parabolic flute for superior chip evacuation: The parabolic flute geometry moves chips away from the cutting zone more efficiently, reducing built-up edge and cutting forces. The result is steadier feeds, less clogging, and longer tool life.
• A clean, precise hole every time: Sharp, precisely ground cutting edges deliver clean entrances and exits with minimal burr, even in thicker sections or harder alloys.
• Extended reach, robust rigidity: The long-series profile provides excellent reach for deep drilling while preserving stability and straightness, helping to minimize deflection in challenging workpieces.
• Versatile metal compatibility: Well-suited for drilling through common engineering metals—steel, stainless steel, cast iron, and various aluminum alloys—making it a reliable choice for fabrication, maintenance, and precision work.
• Efficient heat management: The flute geometry, combined with high-quality steel alloy, minimizes friction and heat buildup, reducing tool wear and enabling longer work sessions between changes.

Ideal for mechanics, fabricators, and precision machinists who demand dependable performance when depth and accuracy matter. Use this drill in compatible drilling machines with appropriate speeds and feeds, apply light lubrication to extend life, and steady your setup to maximize hole concentricity.

From everyday deep-hole tasks to specialized through-hole projects, the Somta Long Series Drill - HSS-E Parabolic Flute - 3.8mm delivers consistent results, helping you complete work faster with fewer tool changes and less rework.
