That's all I use mine for. Works great!
Edit: Be sure to leave the guard on (if it's removable). |

High speed cutoff tools normally have a different style guard than an angle grinder.
I have used an angle grinder as a cutoff tool and taken broken wheel fragments to the face. Wear your eye pro either way. |

On a lot of the angle grinders the cutting wheels don't get enough mounting support and they break apart. I do it all the time, but (as with a proper cut off wheel set up) you always have to be ready for that cutting wheel to go ballistic ... wear eye and face protection!

Make sure you match your attachment speeds with your tool i.e. that the cut off wheel is rated for whatever speed your grinder is spinning. Don't use cheap Chinese wheels, wire brushes, etc., use the guard and always, always wear safety glasses and a face shield.

to me a cutting blade means a saw tooth blade, which I would not put on a grinder, but a abrasive blade will cut something but not considered a cutting blade.
If it's Chinese probably, who knows what they think. |

Your angle grinder is not designed to use cutting wheels, and the manufacturer is merely reminding you of that fact. Most small (4") cutting wheels are meant to be used with die grinders and perform best with more RPM than an angle grinder can produce.

I like to wear both in order to protect my eyes well and my face decently. I do this too. After having a cutoff wheel grenade and the now unbalanced grinder leap out of my hands, take a run down my leg (ouch) and get halfway across the floor before I could rip the power cord out of the wall, I use the guards and assist handle wherever possible. One of the chunks of wheel hit my face shield dead center, would have taken it to my nose/cheek if I hadn't been wearing it. |

When cutting into a material rather than just taking off surface layers the wheel can get caught/jammed which first yanks the user inward then usually frees itself just in time to tear up some flesh. The wheel can also splinter and send pieces flying at 300 ft/s.
Think of it as an assault grinder. |

I use a sawzall for cutting stuff. The grinder is for grinding. For lots of steel fabrication a grinder with a cutoff wheel is a far better way to cut. I use 4" angle grinders, take the guard off and use a 6" disc. You have to be careful it doesn't get away from you but it works well. From a professional standpoint, if you're cutting anything other than wood a sawzall is a time waster. EDIT - Make damn sure you hold on well and brace yourself when you can. I've had grinders bind up and try to get away from me. I hold them so tight that it will stop/burn up the motor or break the gears inside before it would come out of my hands and hurt me. I've ruined a number of grinders that way but after using hundreds if not thousands of 6" cutoff wheels i've never been even close to getting hurt and only had one wheel shatter. My hand and eye protection blocked it though. Every grinder cutoff wheel accident i've seen (about 10) was from someone cutting the wrong way, binding the wheel by being an idiot or having it catch a bit and then basically letting it go because they are afraid of it. |

Pay attention to the RPM rating on your cutting disks. Some are only rated to 1750.
Also, be aware of the same kind of "kick back" if you get on the wrong side of the direction of spin as when you get the nose of a chain saw bar just under the log. Other than that, cut away!

Most of our PI work is done for insurance companies, and most of that is work related accidents.
I have seen moar grinder accidents than I care to list and most of those are pretty ugly. There is no way I would use a standard angle grinder without a FULL face shield. Nothing like having an abrasive wheel turn into shrapnel at high RPM's. ALSO, most angle grinder accidents happen at waist level for some reason, often resulting in catheterization. Can you see where this one is going? Still "Darwin" awards, but without death (just WISH you were dead...) |

I'm not so much worried about the cut-off wheels on grinders as I am the wire wheels.
I had a workpiece held tight in a table vise, and the brush caught. The grinder proceeded to QUICKLY move directly into my torso. The grinder went from 11,000 RPM to 0 in an instant. I honestly didn't know what hit me...It felt as if a tourniquet had been applied directly below my rib cage, and there was this God aweful electric hum as the grinder kept trying to squeeze the life out of me with my t-shirt. I fumbled with the switch for a few more seconds before I was able to disable that motherfucker, I was so taken off guard that it didnt occur to me to simply yank the cord.
I know the reasoning about not wearing gloves when using rotating equipment, but I never imagined that I need to go shirtless next time I use a wire wheel on my grinder. As for the "lawyers" comment. I personally know one that encountered something of the same. He was working on the frame rails on a '71 Camaro with a wire wheel attached to his 4" grinder. The thing decided to take a stroll across his face when he hit the angle wrong. He'll probably be here to post about the incident shortly. 
I'm surprised those assault grinders haven't been banned yet. Scary with a grinding wheel, deadly with a cut-off wheel...and downright psychotic whirling dervishes from hell when a wire wheel is attached. |

You ever try to cut into an inside 90' angle (coming up a curb with a concrete/masonry blade) with the guard on? (Although on the grinder I'm using now, I borrowed my buddies grinder & used a cutoff wheel to cut the guard down - now I can hit an inside 90 & not have chunks of concrete pelting me in the face...)

Use mine to cut with all the time and I've got the scars to prove it. Had one disc come apart and hit my thumb, that hurt like a sumbitch. If you value your sight wear goggles, if you value your fingers and hands in their orginal configuration wear good gloves as well. Happy cutting!

I used a circular saw and a chisel to get the 1/2" the circular saw wouldn't reach. |
