There are three different disc versions for the use of fiber grinders on standard angle grinders.
GT:
Back plate for optimum contour adjustment due to a high degree of flexibility. Conforms to ISO 15636.
H-GT:
High-performance support disc with high durability due to abrasion-resistant, glass-fiber reinforced plastic. Impresses with particularly cool grinding due to radial running cooling fins, as well as high ablation rate of the fiber grinder through a stable, rigid design.
HT-GT:
Flexible and extremely temperature-resistant disc with higher service life due to the temperature-resistant material. Allows precise working thanks to high flexibility. Conforms to ISO 15636.
