What it is
The DeWalt DT3138-QZ abrasive disc is a Ø 150 mm hook-and-loop abrasive with six dust extraction holes, designed for random orbital sanders. Grit 320 is among the finest in the range and is dedicated to ultra-fine finishing and to sanding between coats of paint, where maximum smoothness is required. The pack contains 25 discs.
Sandpaper is an abrasive in sheet or disc form, often hook-and-loop backed, for fitting to sanders or backing pads to sand wood, metal, paint and filler.
What it is for
Used for sanding surfaces before painting, for sanding surfaces, as preparation or as a finish and for sanding wood before varnishing or finishing.
How to use it
Choose the same shape and hole pattern as the backing pad, so that the holes line up for dust extraction. Start with a coarse grit (low number) and move to finer grits up to the finish without skipping too many steps. Sand with light pressure, keeping the machine moving, and change the sheet when it is clogged or worn smooth.
