Roll-Forged HSS Jobber Drill (DIN 338)
This 3.9mm jobber drill is manufactured using a roll-forging process, which preserves the integrity of the material structure. This results in a highly resilient tool capable of withstanding the stresses of arduous drilling tasks, making it a reliable choice for handheld drill operations. Built to DIN 338 dimensional standards, it features a standard helix angle and robust core thickness for consistent performance.
To ensure optimal tool life and accuracy, the maximum drilling depth is calculated as:
*Always ensure the drill is securely held in the chuck and consider the material properties when selecting your feed rate.
