AIR TOOLS CATALOG AIR SANDER 5” VACCUM TYPE AP7335-Ergonomic design-Built for durability-Professional performance-Smooth operation-Ideal for sanding and surface preparation on wood,metal,fiberglass and composite materials and many other substrates.The Tips Of Operating A SanderMove the sander slowly and steadily over the work surface. Racing back and forth is hard on the tool and on the surface.Don' t skip more than one grade of grit as you move from coarse to smooth. Example, you can go from 100 grit to 150 (skipping 120) but don't go from 100 grit to 220 grit. It doesn't hurt to move through each size of grit, from coarse to smoothest, but for all but the finest of work, it's not necessary.Vacuum the surface clean with a shop vacuum and a brush attachment when you're done with each level of grit. This removes any trapped grit particles hiding on the surface. For furniture-grade finishing, wipe the surface clean with a tack cloth (a sticky piece of cloth used to pick up dust; it's sold in the paint aisle) before proceeding to the next grit.Don't tip the sander near the edges because it will round them off. Of course, if you prefer a slightly rounded corner, that can be a good thing. For example, paint sticks better to a gently rounded corner than to a sharp one.

That's the case for the orbital sander and disc sander models, anyways.For belt driven models, speed is given in terms of Feet per Minute (FPM) – the higher the FPM, the faster the belt surface runs. Higher FPM means a higher rate of stock removal, which translates to fewer passes and time needed to work over a surface.For sheet sanders, speed is given in Orbits per Minute, which indicates how quickly the machine can pass the sandpaper over a given spot.For random orbital sanders and bench-top sanders, there's a rate of oscillation given as well. Usually, it is given in terms of times per minute – a bench-top spindle that oscillates 60 times per minute will shift the sandpaper every second. There's a stroke figure usually provided as well, to give you an idea of the extent of the oscillations.Size and SandpaperFor belt sanders, there are standard belt sizes that will fit on models built for them. Smaller sanders can take belts 3 inches wide and 18 inches long, while the more popular length goes up to 21 inches long. Bench-top sanders can take belts 4 inches wide and 24 inches long, or even longer for heavy-duty sanding.Whenever you buy sandpaper, or you are simply checking the ones that come with the sander model, take note of the grit. This figure refers to an estimate of the number of particles in each square inch of the paper – the higher the number, the more densely packed and finer these abrasive particles are.The roughest, coarsest sandpaper have grit in the 40 to 60 grit range. 150 to 180 grit is already considered fine, while there are polishing sandpapers that have grits of 360 and above that can polish material to a satin smooth finish.
