Somta Long Series Drill - HSS-E Parabolic Flute - 6.5mm

Precision deep-hole drilling starts with a tool you can trust. The Somta Long Series Drill - HSS-E Parabolic Flute - 6.5mm is engineered to power through thick workpieces with clean, accurate results, even under demanding cutting conditions. Its extended length pairs with a robust HSS-E core to deliver reliable performance from the first hole to the last.

• HSS-E construction: High-Speed Steel with enhanced heat resistance provides durability and long wear life when drilling tough materials.
• Parabolic flute geometry: Optimizes chip evacuation and reduces cutting forces, promoting smoother starts and steadier hole formation.
• Extended length: Specifically designed for deep-hole drilling, maintaining rigidity and accuracy as you penetrate thicker sections.
• Sharp cutting edges: Deliver clean, true holes with minimal burrs and improved hole surface finish.
• Friction-minimizing flute design: Reduces heat build-up and drag, helping to extend tool life during high-speed operations.

Why it matters: In precision manufacturing, hole quality and tool longevity are inseparable from productivity. This 6.5mm Somta drill maintains consistent hole diameter and surface quality across a range of metals, from softer alloys to tougher steels, making it a dependable choice for repetitive deep-hole tasks.

Ideal for drilling through thick steel plates, structural components, and other demanding workpieces where access and exit quality matter. Pair with appropriate coolant and correct speeds for the material to maximize life and accuracy. For best results, set up your machine with stable support for the long flute and maintain steady feeds to minimize vibration. The Somta Long Series Drill is a trusted ally for machinists, fabricators, and workshop professionals who demand repeatable, high-quality deep-hole performance.
