: 20 Angle Grinder Flap Discs 41/2" Flat 80 ...
Oct 06, 2014· I was grinding/sanding 2x2 square tubing for about 2 hours straight. The results were very good with these flap disk. They take off a decent amount of mettal and leave a pretty smooth surface. The packing sucks, but hey they''re cheap. In order to fit my Makita 9557PBX1 41/2Inch Angle Grinder I needed a washer/spacer.
