Garryflex Block 240 Grit is an abrasive block manufactured by Garryson. It is a precision-made block of abrasive topped with a durable layer of yellow plasticised sheet. Its unique design allows the user to press down on the sheet to enhance the effect of the abrasive surface in grinding. The block is manufactured from a special grade of aluminium oxide, bonded to a reinforced bonded nylon backing with a Velcro-compatible system. It is ideal for grinding, levelling and removing fine burrs and for general purpose deburring and grinding. It can also be used in portable machines, like polishers and grinders, for industrial and automotive applications.
