2mm HSS Long Series Drill (DIN 340)
Specialized Long-Reach Drill for Deep Hole Applications
Long-Reach Drilling Performance
This 2mm HSS jobber drill conforms to DIN 340 standards, providing the extended reach necessary for deep-hole drilling tasks. To ensure successful operation in long-reach applications, it is essential to employ low feed rates and perform frequent drill pecks (repeated chip evacuation) to prevent chip clogging and tool breakage.

Operational Guidance
Deep hole drilling significantly increases the risk of chip buildup. Always ensure consistent chip evacuation by retracting the drill periodically. The maximum drilling depth (L₂) for this tool is calculated as:
*Note: For diameters ≥ 2.4 mm, these drills are provided with a vaporised surface finish to further assist in demanding drilling conditions.
