Learn more about Klarna
The Somta Long Series Drill - HSS-E Parabolic Flute, 2.1 mm diameter, is engineered for serious deep-hole work in metal. Its extended reach allows you to drill through thick sections in a single setup, improving hole alignment and reducing rework in demanding fabrication environments.
At the heart of the bit is HSS-E (High-Speed Steel with extra wear resistance), which delivers superior durability and heat tolerance. That means you can push harder, run faster, and maintain edge life even when drilling tougher alloys or stainless steels.
The parabolic flute design is the standout feature for chip evacuation and cutting efficiency. Parabolic flutes move chips away from the cutting edge more quickly, reducing cutting forces and heat buildup. The result is smoother drilling, fewer burrs, and longer tool life in continuous production.
Sharp, precision-ground edges team with the flute geometry to deliver clean, round holes with minimal wander. Expect tight tolerances and repeatable performance across thick workpieces, whether you’re working on steel plates, cast iron, or alloyed metals.
Who benefits most
- Metal fabricators drilling through thick panels and blocks with high accuracy
- CNC operators and manual machinists needing long-reach drills for through-holes
- Maintenance technicians creating access holes in equipment housings and enclosures
Practical tips for best results
- Match your speed and feed to 2.1 mm diameter HSS-E tools; start with conservative parameters and adjust based on chip formation and surface finish.
- Use light lubrication or dry machining depending on material and machine capabilities to minimize heat buildup, and allow the parabolic flute to ventilate chips effectively.
- Ensure the drill remains perpendicular to the workpiece; for deep holes, employ pecking cycles to clear chips and maintain hole quality.
In short, the Somta Long Series Drill - HSS-E Parabolic Flute, 2.1 mm, is built for professionals who demand reliable deep-hole performance, extended tool life, and consistent hole quality across thick metal workpieces.
