PFERD TOOLS POLIFAN-CURVE CO-COOL SGP STEELOX, 4-1/2" x 5/8"-11, 60 Grit

Holding up well, these are much better than a normal flap disc at cleaning up welds on inside curves. Highly recommended.

Good for grinding inside corners

Good, but came only in a plastic bag

The disk works great but use it only when needed for tight inside corners. I gave it four stars because of the price.

The only problem with this product is that it's so good I too often use it on jobs that would be done with the much cheaper flap disk. I've solved this problem by buying a 2nd angle grinder do I can have one loaded with this product and the other with a cut-off wheel or flap wheel. BTW, getting this wheel of is difficult. I have to lock it in a vise and rotate the grinder. Problem solved by having the 2nd grinder. This product gets in places otherwise difficult to get to with standard flap wheel. I bought a 2 inch pneumatic angle grind to get into small places but use it less now that I have this product. It takes metal off quickly. This would be a "must have" for metal artists.

I know Pherd is expensive. But these last and last. Will save your bacon on a finish weld that shows. Wanna make that weld that shows invisible. You need this.

I expected more life on these disk given my research and the namesake. Smoothing edges of 1/4" bent aluminum and surfacing tops. Didn't seem to last very long for almost $20...

Works like a champ. Threaded right on. Took a few passes to sharpen and done. Get one. Sharpen (not too much) your shovel while you’re at it.

I decided to invest in a more expensive disc as there ones I normally buy were out of stock. The disc didn't last as long as the cheaper ones. Quite disappointed. Very poor value for the usage. I was feathering steel welds.

Works where flat wheel can’t access

Disco para polir metal e inox de excelente qualidade da Pferd. Muito bom mesmo principalmente porque esse disco tem lixa dos dois lados e não precisa ficar virando a lixadeira todo tempo.

Bin begeistert

Funziona abbastanza bene. Tre stellle perché le foto sono ingannevoli: l’offerta è per un solo disco, non due.. il che porta anche il prezzo un po’ troppo in alto considerando che in fondo è materiale di consumo..
