Description
The Somta Long Series Drill - HSS-E Parabolic Flute - 1.1mm is engineered for deep-hole drilling where reach and reliability matter most. Its extended length delivers the depth you need without sacrificing hole accuracy, making it an ideal choice for thick workpieces and through-holes.
- Long-length design for deep work: reach through thick materials with stiffness and minimal deflection for true, consistent holes.
- HSS-E construction: enhanced durability and heat resistance to handle demanding drilling tasks without dulling quickly.
- Parabolic flute geometry: efficient chip evacuation and reduced cutting forces, resulting in smoother starts and longer tool life.
- Sharp cutting edges: clean, precise holes with reliable diameter control across applications.
- Friction- and heat-minimizing flute design: sustains performance over extended drilling runs and tough materials.
- 1.1 mm diameter: ideal for small-diameter, deep-hole work in metal, electronics enclosures, and precision assemblies.
In practical terms, you gain accurate hole starts, reduced chatter, and dependable performance when drilling through layered or thick workpieces. The parabolic flute keeps chips moving away from the cutting edge, minimizing clogging and heat buildup so you can push for deeper holes with confidence.
Who should use this drill? machinists, fabricators, electronics technicians, and workshop professionals who require consistent deep-hole capabilities with small-diameter precision. It’s a smart fit for projects where through-holes must be clean, straight, and repeatable.
Tips for best results: secure the workpiece firmly, use appropriate spindle speeds and feeds for metal drilling, apply cutting fluid where suitable, and avoid forcing the drill—let the long flute manage chip evacuation and cutting in a controlled manner.
Upgrade to the Somta Long Series Drill - HSS-E Parabolic Flute - 1.1mm and tackle deep-hole projects with a tool built for precision, durability, and reliable performance.
