A clogged disk equals an uneven disk and when spinning at very high rpm equals boom. Should always inspect the disk. If some clown before you has clogged it for the next person, chuck it.
Caught a cock head on site (lucky for him) had a cut quick blade (14") worn down and was attempting to put it in a 7". Quick cut blades are rated for 4400rpm 7" grinder 8600rpm. No visor nadda it would have blown apart at 8600 rpm would have been nasty.
Have a google of Angle grinder injuries PHARKN NASTY!!
Heres a ripper for you true story, Italian guy up the airport doing home renos and was cutting in some door architraves.
Saw wouldn't fit so he removed the saw blade and fitted it to the 9" grinder. Turned it on and lined it up for a cut ,,,,,,,,,,,,,,,
as soon as it touched the timber it bit took off and ended up embedded in his shoulder blade, nasty as you say.
He went to Emergency with saw in his back, very lucky person an idiot but lucky.
A general rule for cutting aluminum is to treat it as wood instead of metal and use wood tools like a toothed blade on a drop saw as mudrunner said.
A mate pushed his alloy bullbar onto his wheel when his 4x4 hit a tree and used a chainsaw to cut it off. Natural reaction from people was that it's a crazy idea but it works better and safer than a grinder with surprisingly little wear on the chain.
Can see that working as it would be throwing pieces of alloy out and not clogging the blade.
Good out come in an emergency situation, Blades are what $30 each,
Yeah the chain really didnt wear that much at all. A sharpen up and it was as good as new. Probably about the same as 3 loads of wood worth of wear
