The abrasive sleeve holders identified by H have a higher hardness allowing a stronger grinding pressure. They are less elastic and are remarkably suitable for grinding edges. Standard performance of abrasive sleeve holders = hardness approx. 6570 Shore A special performance of abrasive sleeve holders H = hardness approx. 80 Shore A
Strengths
The grooves allow the extension of the support and the sleeve is perfectly held in place during the work. Quick attachment and removal of the sleeve. The extreme precision of the overlay ensures the correct positioning of the abrasive sleeve on the sleeve holder during the work.
