SA7 unitised wheels 150mm diameter x 6mm wide with a 25.4mm centre hole contain a very fine silicon carbide grit but they are still capable of removing stainless steel fillet welds.
Use the SA7 for…
tig weld removal in corners, deburring, dressing heavier welds on aluminium, and pre-polishing where more aggression is required than with the SA5 or SA6
