Take your deep hole drilling to new depths with the Somta Extra Long Series Drill - HSS-E Parabolic Flute, 12.5 mm x 480 mm. Engineered for precision and durability, this drill bit is built to reach into thick workpieces while delivering clean, accurate holes from start to finish.
The extra-long 480 mm overall length provides the reach you need for deep-hole projects, enabling you to bore through substantial materials without swapping in multiple tools. The HSS-E construction delivers enhanced heat resistance and extended tool life, making it a reliable choice for demanding metalworking environments where uptime and consistency matter.
The parabolic flute design is more than a hallmark—it actively improves performance by optimizing chip evacuation. Efficient chip flow minimizes clogging and reduces heat buildup, helping maintain cutting efficiency and hole accuracy even during extended drilling sessions. Sharp cutting edges ensure clean entry and true hole diameter, while the flute geometry reduces friction so you can maintain steady feeds without premature wear.
Key benefits at a glance:
- Extra-long reach: 480 mm overall length for deep holes in thick materials.
- Precise hole quality: sharp edges and parabolic flute for clean entry and exit.
- Efficient chip evacuation: parabolic flute minimizes clogging and heat buildup.
- Durable, heat-resistant material: HSS-E construction extends tool life in challenging metals.
- Versatile applications: ideal for deep-hole drilling in manufacturing, fabrication, mold/die work, and heavy equipment maintenance.
Practical tips for best results: use appropriate coolant or lubrication to maximize tool life, maintain a steady feed to prevent deflection in long-reach drilling, and start with a pilot hole to guide the bit through tougher workpieces. Align spindle speed and feed rate to the material and drill diameter to optimize performance and minimize wear.
The Somta Extra Long Series Drill - HSS-E Parabolic Flute, 12.5 mm x 480 mm is a precision-focused solution designed for professionals who demand reliable performance when reaching into deep cavities and through-thick sections. When depth, consistency, and long-term durability are non-negotiable, this drill bit delivers the reach and quality you rely on.
