Description The mini flap disc is a tiny tool that saves time, labor, money, and effort because it grinds and finishes simultaneously. The Bluefire disc is made of zirconia alumina, which is strong enough to elongate its life up to 30% longer on mild carbon steel and welds. Bluefire mini flap disc is fit for farm equipment, propane tanks, civil/construction/military equipment, and plate steel/structural steel.
