For third-sheet orbital sanders that have a hook and loop backing pad.
BACKING: Hook and loop
The orbital sander sheets have been precut to fit most third sheet orbital sanders.
The abrasives are made of aluminium oxide and can be used on either wood or metals.
Orbital sanders cause swirl marks. A stray piece of grit or a larger bit of dust could be embedded on the abrasive sheet whilst sanding. Try to move the sander slowly when sanding. Any fast movements can cause noticeable swirl marks.
