The magnets are designed for professional manufacturing and protected by international patents. All of them have very strong magnetic force in order to ensure secure and absolutely precise fixing on the core-bit barrel, even when working with glowing segments.
The chrome-plated surface and the special high-energy magnet ensure that adhesive power and precision remain constant during thousands of soldering jobs.
The holder's shape and the floating mounting of the pole plates compensate the barrel's thermal expansion during soldering and any minor deviations from the right angle during fixing of the holders.
The 4 different projection lengths (0.5/0.75/1.0/1.25 mm) per holder are marked clearly to make them easy to find.
