Sorry, I was not meaning that they are not a hazard. The issue was they restricted engineers that had the appropriote level of training to use an angle grinder to cut metal, who know what PPE to were (plus it was written into the JSA) to only use 3mm cut-off wheels which cause more heat and take longer to do the job.

Lowe's has the DeWalt ones (at least in this area they do) that are made for cutting stainless steel. Says it right on the disc. The discs made to do this job are thinner so that they do a better job.

I worked for GE Aerospace for a while. They outlawed Exacto knives after an engineer cut himself. It was absolutely forbidden to posses one for my 5 years there.

Hahahaha last place I worked did the same thing and man did the sparkies hate it. Thing was the operators had to cut open bags of powder to dump in the dissolving tanks, 40 bags to a pallet. They had special safety knives that were spring loaded so the blade would retract once it stopped cutting the bag. They gave the sparkies the same knives and they would need to keep extending the blade a bunch of times when stripping the shealthing off cable - kind of made the job more hazardous! Then they said you had to use the same knives to break down shipping boxes (the heavy cardboard ones that are stapled together), that was super dangerous now with the safety knives. Eventually some people found out that if you didn't extend the blade fully that safety mechanism did click in and it wouldn't retract

YES!
I am a designer for a metal fabrication company. Our guys use grinders on a daily basis. They use safety glasses AS WELL AS full face shields. We still have someone that has to go get crap dug out of their eyes about once a month.
Take care of your eyes folks! You can't get new ones!

Also, think about who is around you while grinding. DON'T let little kids be anywhere close to a grinder. As in about a 20-40 foot radius.

I just got a clear shield to replace the darker one in a welding shield setup. Since the old (welders shield) is scratched to hell and back again, and darker (oxy-acy welding) I had picked up another entire setup. So now I can have one dedicated for grinding/drilling/etc. and another for welding. I also wear glasses, so I have more protection layers from a direct strike. The new shield has a good wrap-around effect.

Looking into the maunal on the grinder I bought....Am I going to be able to find a wheel that works here?

The Grinding Wheel MUST be:
• rated to at least 11,000 RPM.
• no larger than 4-1/2″ in diameter.
• fitted with a 7/8″ round arbor hole.
from 0.16″ to 0.28″ thick.
• a type of grinding wheel suitable for
surface grinding, not edge grinding.
• dry and clean.
• proven undamaged by inspection and
by the ring-test explained below.



0.16 is the smallest it will take? Am I wrong here?

smallest thickness, correct. and 4.5" is the largest diameter it will take. go to home depot or Harbor Freight and they should have something that fits just fine. that's a pretty standard range.

I tried buying the ones you linked me from harbor freight...well the same dimensions...but from HD. The wheel didn't fit on the grinder. It didn't make a tight fit...even with the spacer in there...there was slop. User error?
