Somta Long Series Drill - HSS-E Parabolic Flute - 5mm

Meet the Somta Long Series Drill - HSS-E Parabolic Flute - 5 mm, a purpose-built solution for deep-hole drilling in thick materials. When you need a precise through-hole in heavy setups, this drill delivers steady performance and consistent results from first plunge to final exit.

Crafted with HSS-E (High-Speed Steel Enhanced) for superior hardness and heat resistance, it maintains sharpness under demanding speeds and loads. The longer flute length provides the reach required for through-thick workpieces, reducing the need to reposition and re-clamp—saving time in production runs and ensuring dependable hole placement.

The parabolic flute design is the standout feature here. It accelerates chip evacuation, minimizes cutting forces, and lowers friction between the tool and workpiece. That combination translates to cooler operation, less burr formation, and longer tool life, even when drilling challenging metals.

• 5 mm diameter for tight, accurate holes in demanding materials
• Long-series length enables deep holes in thick workpieces without frequent reloading
• HSS-E construction delivers enhanced wear resistance and heat tolerance
• Parabolic flute improves chip clearance and reduces cutting forces for smoother drilling
• Sharp cutting edges and robust flute geometry promote clean hole finish with minimal deflection

Ideal for machinists, fabricators, and toolmakers tackling automotive frames, structural components, castings, or heavy metal work where hole depth matters. This drill defines durability and precision, offering longer tool life and more consistent hole geometry compared to standard drills. To maximize performance, match speeds and feeds to your material, maintain proper lubrication, and use steady feeds to leverage the drill’s advanced flute geometry.
