Somta Long Series Drill - HSS-E Parabolic Flute - 1.9mm

Somta Long Series Drill - HSS-E Parabolic Flute - 1.9mm is a precision deep-hole drill built for metalworking professionals who demand reliability in tough conditions. When you need to pierce thick materials with clean, accurate holes, this long-reach drill delivers.

The HSS-E construction combines durability with heat resistance, standing up to extended drilling sessions without losing edge sharpness. The parabolic flute geometry isn’t just about style—it actively improves chip evacuation and reduces cutting forces, which minimizes built-up heat and extends tool life, even in demanding alloys.

A long-series design provides the reach required for deep holes, while maintaining rigidity enough to keep hole walls straight and true. Sharp cutting edges produce clean entry and exit, reducing the need for rework and ensuring precise hole diameters at every depth.

Key advantages at a glance:

• Long reach for deep-hole drilling in thick workpieces
• HSS-E construction for durability and heat resistance
• Parabolic flute for efficient chip evacuation and lower cutting forces
• Sharp, precise cutting edges for clean holes
• Flute geometry minimizes friction and heat buildup to extend tool life
• Suitable for a range of metalworks, including hard-to-machine materials

Practical use scenarios:

• Drilling deep through thick steel plates, cast iron, and alloyed metals in fabrication and construction workflows
• Precision holes for fasteners in automotive chassis components or heavy machinery housings
• Mold and toolmaking tasks that require deep, straight bores with a smooth wall finish

Tips for best results:

• Match cutting speed and feed rate to the material; start with moderate RPM and adjust based on chip formation
• Use a peck drilling approach to clear chips and prevent clogging in long holes
• Apply cooling lubricant to control heat buildup, especially in harder alloys
• Keep the drill straight and aligned to avoid wandering in deep bores

Choose the Somta Long Series Drill when your projects demand consistent hole quality, extended tool life, and dependable performance in deep-hole drilling tasks.
