What it is
The DeWalt DT30621-QZ Extreme flap disc belongs to the range of professional abrasives for sanding and deburring with an angle grinder. Made with a flat profile, it carries grit 80, ideal for intermediate finishing work that removes material in a controlled progression, leaving a uniform surface ready for subsequent operations.
A flap disc is an abrasive made of overlapping cloth flaps, on a disc for angle grinders or on a shank for straight grinders, that roughs down and finishes metal and wood.
What it is for
Used for sanding metal, from roughing to finishing, for deburring metal after cutting and drilling and for grinding and cleaning up weld seams and burrs.
How to use it
Fit the disc on the angle grinder, or insert the shank-mounted flap wheel in the collet of the straight grinder or drill, observing the maximum speed. Work with light pressure at a slight angle, keeping the tool moving so as not to overheat or mark the workpiece. Progress from coarse to fine grits for finishing, and replace the disc when the cloth is worn down to the backing.
