Where can I purchase a new rubber pad for the PalmGrip25 sander, ref CLM240PS please? The sponge/rubber pad is black in colour, with 6 ventilation holes and 4 recessed securing holes, to thake the screws. It measures 10cm x 11cm and is about 4/5mm thick. Mine has worn down to the metal at one side.
