Learn more about Klarna
Designed for deep-hole drilling where reach and precision matter, the Somta Extra Long Series Drill - HSS-E Parabolic Flute (5 mm x 315 mm) is built to deliver dependable performance across demanding applications. The extended length lets you reach deep into thick workpieces in a single setup, while the HSS-E alloy provides robust wear resistance and heat tolerance for longer tool life.
The parabolic flute design is at the heart of this drill’s standout performance. It streamlines chip evacuation, reducing clogging and back-pressure so you can maintain a steady feed and consistent hole quality even as depth increases. The result is cleaner holes with tighter tolerances and fewer interruptions caused by chip buildup.
- Diameter and length: 5 mm cutting diameter with a 315 mm overall length for exceptional deep-hole reach
- Material: HSS-E (High-Speed Steel Enhanced) for superior hardness, heat resistance, and extended tool life
- Flute geometry: Parabolic flute optimizes chip evacuation and minimizes friction and heat buildup
- Cutting performance: Sharp cutting edges deliver clean, accurate holes with minimal wandering
- Intended use: Ideal for deep-hole drilling in thick workpieces and situations where standard-length drills can’t reach
- Operational tips: Pair with appropriate machine speeds and cutting fluids to maximize life and maintain hole quality; withdraw periodically to clear chips
Who benefits most: machinists and fabricators tackling deep-hole tasks in steel, stainless steel, aluminum, and other common metals. This drill reduces the need for multiple setups or tool changes, boosting efficiency in tool-and-die shops, automotive fabrication, and precision engineering environments.
Why choose this Somta drill over alternatives? Its extra-long reach combined with HSS-E durability and the parabolic flute’s efficient chip management work together to deliver reliable performance in challenging depths, maintaining hole straightness and finish without frequent tool changes or rework.
Equip your workshop with the Somta Extra Long Series Drill for deep-hole projects that demand reach, resilience, and consistently clean results.
