Somta Long Series Drill - HSS-E Parabolic Flute - 1.7mm

Meet the Somta Long Series Drill — HSS-E Parabolic Flute — 1.7 mm, a precision drill bit engineered for demanding deep-hole drilling tasks. With its extended length, this tool effortlessly penetrates thick workpieces, delivering consistent, straight holes from start to finish. The HSS-E (High-Speed Steel-Enhanced) construction provides exceptional durability and heat resistance, making it a reliable companion for tough materials and high-temperature drilling environments.

What makes this drill unique

• Long length for deep holes — designed to reach through thicknesses that standard drills can’t touch, reducing the need for multiple passes or setups.
• HSS-E durability — built to withstand demanding drilling tasks and maintain cutting efficiency under heat.
• Parabolic flute geometry — optimized for rapid chip evacuation, which minimizes clogging and lowers cutting forces for smoother entry and exit.
• Sharp, precise cutting edges — delivers clean holes with reduced burrs and improved hole quality in a variety of metals.
• Friction-reducing flute design — helps dissipate heat build-up, extending tool life even in continuous, heavy-duty use.

Ideal use cases

• Deep-hole drilling in thick metal plates and components where access is constrained
• Fabrication, maintenance, and repair tasks in automotive, aerospace, and general engineering
• Precision drilling in alloys and ferrous materials where hole concentricity matters

How this drill translates into real-world results

Users choose the Somta Long Series Drill when they need dependable performance over long runs, without sacrificing hole accuracy. The combination of a long length, parabolic flute, and robust HSS-E construction means fewer tool changes, steadier feeds, and better hole-to-hole consistency. It’s particularly beneficial for setups where backing material is limited or where through-thickness clearance is essential.

Practical tips for best results

• Use appropriate cutting speeds and feeds for your material to maximize life and minimize deflection.
• Apply a light steady lubricant or cutting fluid to reduce heat and prolong edge life on metals.
• Support the workpiece and maintain straight, axial drilling to avoid side loading, which can dull the parabolic flute.
• Periodically pause to clear chips, especially on long drilling operations, to maintain consistent hole quality.

Quality machining starts with a reliable drill. The Somta Long Series Drill — HSS-E Parabolic Flute, 1.7 mm — is your go-to solution for precise, deep-holed results in demanding metalwork.
