Description
Somta Extra Long Series Drill - HSS-E Parabolic Flute - 14mm x 310mm is a versatile tool designed specifically for deep hole drilling applications. With its extended reach, this drill enables access to features deep inside workpieces that shorter bits can’t reach, reducing the need to reposition or switch tools mid‑work.
The HSS‑E construction delivers durability and heat resistance for prolonged tool life, making it a reliable choice for demanding tasks in busy workshops. The parabolic flute design optimizes chip evacuation, helping to prevent clogging and maintain steady cutting performance as you drill deeper.
Its sharp cutting edges work in concert with the flute geometry to minimize friction and heat buildup, promoting clean, accurate holes with good surface finishes from entry to depth. You get consistent hole size and reduced wandering as the drill engages material from the initial cut to the bottom of the hole.
- Extra-long reach (14mm diameter, 310mm overall length) designed for deep-hole drilling and accessing recessed areas
- HSS‑E construction for durability and heat resistance under heavy cutting
- Parabolic flute geometry that enhances chip evacuation and reduces clogging
- Sharp cutting edges for clean, true holes and reliable starts
- Flute design that minimizes friction and heat buildup during prolonged drilling
Ideal use cases include drilling deep holes in thick workpieces, deep pockets, and other challenging metalworking tasks where depth and precision matter. For best results, maintain a steady feed and secure workholding to minimize deflection and maximize hole quality.
