Somta Long Series Drill - HSS-E Parabolic Flute - 7.6mm

The Somta Long Series Drill – HSS-E Parabolic Flute – 7.6mm is built for serious metalwork where precision, depth, and reliability matter. Designed for deep-hole drilling, this drill combines a long flute length with a robust HSS-E body to deliver consistent holes through thick materials.

Key features that set it apart:

• Long reach, precise results — specifically engineered for deep-hole work, allowing you to drill clean, accurate holes without frequent tool changes.
• HSS-E construction — high-speed steel with enhanced heat resistance for demanding drilling tasks, maintaining sharpness under tough cutting conditions.
• Parabolic flute design — optimized chip evacuation and reduced cutting forces, which translates to smoother penetration and less heat buildup.
• Sharp, reliable cutting edges — engineered for clean hole geometry and minimal revs-to-finish time, improving productivity on busy shop floors.
• Flute geometry reduces friction — helps extend tool life by minimizing heat and wear during prolonged drilling sessions.
• Diameter and length profile — a 7.6mm drill with a long flute length (110) tailored for through-thickness applications where standard drills fall short.

Who benefits most? machine shops and fabrication facilities tackling thick steel, cast iron, or other hard-to-reach materials will appreciate the dependable performance and consistent hole quality this drill delivers. It’s ideal for through-holes, mounting bores, and any scenario where you need deep penetration without compromising accuracy.

Practical usage tips to maximize results:

• Match speed and feed to the material being drilled; start with conservative settings and increase gradually to maintain clean chips and stable centering.
• Use steady, low-vibration feeds and ensure the workpiece is securely clamped to prevent deflection during deep-hole drilling.
• Maintain sharp cutting edges; replace or re-sharpen when you notice edge dulling to preserve hole quality and prolong tool life.
• Apply appropriate lubrication or coolant for heat management, especially on tougher metals or when drilling to full depth.

In one drill, you get a precise 7.6mm bore with the depth you need, backed by Somta’s reputation for durability and performance in metalworking. If you’re looking for a dedicated deep-hole solution that won’t back down when the going gets thick, the Somta Long Series Drill – HSS-E Parabolic Flute is a dependable choice.
