If you are wishing to grind back tig welds on a steel fabrication then you are almost certainly after a high quality finish and are quite likely to be putting a good quality wet paint finish onto the metal. So there is no point grinding away the metal with a P36 grit disc as you might as well have stick welded it!!
Control and a good quality finish are the order of the day. But that can mean high disc wear rate.
That is why we are recommending the new Cibo Ceramics fibre discs.
FX87 P80 grit fibre discs will give you great cut rate, good control of the grinding action, a cool cut and an excellent finish.
Be impressed!!
