Somta Extra Long Series Drill - HSS-E Parabolic Flute - 2mm x 135mm

Somta Extra Long Series Drill — HSS-E Parabolic Flute, 2 mm x 135 mm — engineered for deep-hole precision with extended reach. This drill bites cleanly into metals and select plastics, delivering accurate holes even in challenging workpieces where standard-length bits fall short.

• Extended reach for deep holes: With a 135 mm overall length, it effortlessly accesses recessed cavities and through-holes without repeatedly repositioning the workpiece.
• HSS-E durability: Made from high-speed steel with enhanced cobalt content for superior wear resistance, heat tolerance, and longer tool life in demanding drilling environments.
• Parabolic flute design: Optimized chip evacuation channels prevent clogging, minimize heat buildup, and maintain a consistent bore diameter from start to finish.
• Sharp, stable cutting: Precisely ground cutting edges deliver clean entry and true hole geometry, reducing wandering and ensuring concentric results in delicate workpieces.
• Versatility across materials: Ideal for deep-hole drilling in steel, stainless steel, aluminum, and certain plastics, making it a reliable choice for assemblies, enclosures, and fixtures.
• User-friendly performance: Compatible with standard drill chucks and conventional drilling speeds when paired with appropriate feeds and cutting fluid for metal work.

Practical tips for optimal results:

• Securely clamp the workpiece and establish a center mark or pilot hole for precise starting guidance.
• Begin with a slow, steady feed and moderate speed; increase only as the material allows to prevent deflection.
• Use cutting fluid or light oil when drilling metals to reduce heat and extend tool life; wipe away chips regularly to maintain visibility and bore quality.
• Withdraw the drill occasionally to clear chips and prevent chip packing in the flute.
• Turn off the drill as soon as you finish the hole to minimize workpiece vibration and edge work damage.

When you need to reach deep into a workpiece without compromising hole quality, the Somta Extra Long Series Drill — HSS-E Parabolic Flute — 2 mm x 135 mm is the dependable choice for professional machinists and dedicated hobbyists alike. It blends durability, precision, and deep-hole capability into a single, reliable drill bit that keeps your projects moving smoothly.
