angle grinder discs

[LT1BRD]

for those of you who use grinders a lot, is there a disc that allows you to grind...or sand over edges or on pipe without making it all edgey and angeled? a normal grinding pad only does straight grinding and i want to grind welds on pipe and make it look smooth like the rest of the pipe...without buying a pipe sander. i guess it would have to be a kinda thick pad that flexes over the curve of the metal?

Like this. You can get them at any welding supply store usually.

so flap discs are good for sanding smooth, round pipe?

You can work around curves better with them. I have not tried on pipe.

They work really well for blending and smoothing. They come in different grits, like sand paper. The lower the number, the courser the grit and the quicker it cuts.

The flap disc I always liked the best were called Tiger disc. Those things would take off metal in a hurry but leave the surface nice and smooth. I haven't used one in years because my boss bought a bunch of regular discs. And I haven't been able to use them up yet and go buy some more of the Tiger disc.

NOTE: flap discs are awesome, if you are not familiar with them you want to buy a coarser grit than you would with regular resin fiber.... the relaxed grind of the media cuts fast but leaves a finish of a finer grit.

Simply put, if you would normally use an 120 grit resin fiber disc to get the finish you desire... you will want to purchase an 80 or 60 grit flap disc to accomplish the same finish. The tool will cut way more efficiently and last longer with the same finish as the comparable resin fiber at 120 G

They work awesome, they just wear out alot quicker than a regular stone disc.

A lot of that depends on the quality. I have ones that are around $15 each and they last well over 10 times longer than the $3-$5 ones from the hardware store. When it comes to abrasives generaly the more you spend the cheaper it is because they last many times longer than than the extra cost.

On iron, I use a new "Pearl Maxidisc" PN# max45120 A120 grit, to rough grind the material. I then follow up with a good used disc for a smoothe look. I have used Tiger discs as well, but the Pearls last alot longer. On Stainless I "Clean" the weld on a die grinder with a 3M EXL Unitized wheel 2S fin 3"x1/2"x1/4". To prep the surface for welding Stainless, I use a Merit 80 grit 1" flapper wheel on a die grinder.

A belt sander with no backing behind the belt works good for finish. The belt curves to the pipe.
