GOLD DISC (50 PIECES) 40 GRIT 150MM WITHOUT HOLE HOOK AND LOOP
Abrasives for Ø150mm random orbital sanders.

It gets the job done fast and saves you time and money. Thanks to the premium bonded aluminium oxide abrasives. The hook and loop systems allows the sanding disc to be used with a random orbital sander. The sander mimics the circular motion of manual sanding to achieve a brilliant finish with minimum swirl marks.
The Gold range abrasives are mostly used in the automotive industry for
paint preparation and surface flattening between
coates of paint.
Most random orbital sanders have variable speed, which is a necessity when working with paints. Too much speed will result in too much friction, which will cause holograms, loss of gloss and clogging up the abrasives.
What is grit?
When talking about sandpaper 'grit' is a reference to the number of abrasive particles per inch of sandpaper. The lower the grit the rougher the sandpaper and conversely, the higher the grit number the smoother the sandpaper.
This make sense if you imagine how small the particles on an 1000-grit sandpaper would need to be to fit into a 1' square (25,4mm square). Sandpaper is referred to by the size of its grit (Example 120-grit sandpaper or P120 sandpaper).
You need to choose the grit size of sandpaper depending on the particular job you are trying to accomplish. For heavy sanding and stripping, you need coarse sandpaper measuring 40- to 60-grit; for smoothing surfaces and removing small imperfections, choose 80- to 120-grit sandpaper. For finishing surfaces smoothly, use a super fine sandpaper with 360- to 600-grit. Many jobs require you to “go through the grits.” This means you start the project using lower-grade grit and use finer pieces of sandpaper as you progress. Each time you advance to a higher grit sandpaper, you remove the scratches from the previous layer.
