I had to cut some 8mm steel yesterday and today. I dusted off my trusty 9"
angle grinder and set to work. I wore out one wheel (Flexovit)and the only
one I had available was an 8" Flexovit (Aussie made). I wore it out in
short
order. It's cutting performance was what I would term "satisfactory".
About
2cm/minute (best guess). I toddled off to Bunnings this afternoon to buy
some more wheels. Unfortunately, the Flexovit wheels had the wrong size
mounting hole, so I purchased a 5 pack of Trojan (Chinese made) branded
wheels. Hopeless cutting performance. I mean, REALLY BAD. It took about 5
minutes to cut 2cm. The wheel didn't wear down and faster or slower than
the
Flexovit. It just hardly cut the metal at all.
What gives?
The technology is hardly state of the art. All wheels are rated for
ferrous
metal cutting. Since most of my cutting is done with a 4" grinder, this is
not something I've experienced before. I've not experienced this sort of
poor performance when cutting concrete, bricks and stone. Are all these
Chinese wheels bad, or did I get a bad batch?
The Torjans are going back on Monday. I doubt that I'll buy them again.
