Somta Long Series Drill - HSS-E Parabolic Flute - 6.4mm

The Somta Long Series Drill - HSS-E Parabolic Flute - 6.4mm is engineered for professionals who demand consistent, high-quality deep-hole drilling in demanding workpieces. Its extended reach lets you bore accurately into thick materials without sacrificing hole integrity or alignment, making it a trusted tool for metalworking, fabrication, and maintenance tasks.

Key features that set this drill apart

• Long length for deep-hole capability: Designed to reach through thick workpieces where shorter bits struggle, delivering straight, true holes from start to finish.
• HSS-E construction: High-speed steel with enhanced heat resistance to withstand the demands of extended drilling sessions and tougher materials.
• Parabolic flute design: Optimized chip evacuation to prevent clogging, reduce cutting forces, and maintain a smooth cutting action even in challenging environments.
• Sharp cutting edges: Precision-ground geometry ensures clean, precise holes with minimal wandering and better surface finish.
• Flute geometry for lower friction: Reduced friction and heat buildup help extend tool life and maintain consistent performance over many holes.

Why this drill is the right choice for your workshop

When you’re drilling through thick materials, roundness and accuracy matter. The Somta Long Series Drill delivers reliable hole quality from the first hole to the last, even in tough metals. The combination of long reach, durable HSS-E material, and efficient chip evacuation means fewer interruptions for bit changes, less rework, and longer tool life—so you can complete projects faster with fewer tool-overs.

Ideal use cases

This drill is well-suited for deep-hole applications in metalworking environments where access is limited or material thickness demands a longer bit. It excels in fabrication, machinery maintenance, and workshop tasks that require true, clean holes without compromising drill stability. Use it for through-holes in thick plates, components, or assemblies where precise alignment and hole quality are critical.

Practical tips for top performance

• Maintain a steady feed and avoid aggressive plunging to preserve cutting edges and achieve uniform hole diameters.
• Use appropriate lubrication or coolant to manage heat buildup and extend tool life in demanding work.
• Ensure workpiece is properly clamped to prevent deflection, which can affect hole accuracy in deep drilling.
• Start with a light pilot or center mark to establish a true entry point before progressing to full-depth drilling.
