I have used many different brands of cut off disc in a 4 1/2" grinder working as a Union Pipefitter.
The Walter Zip or Zip + is hands down the best cut off disc I have used.

They are directional,so mount them with the arrow pointing in the direction of ratation and they even last longer than is incorrectly installed, LOL.
$3.25 a disc but worth every penny.

If you do a lot of cutting, get a larger guard for your grinder and use the 6 inch discs, you will get a lot more feet of cut per dollar spent.

I use small 3" wheels in my battery powered DeWalt DC550B cutoff tool. I also use rotary files in it to open up holes. The DeWalt is really a handy tool for quick work and no cord to drag out. The 550B uses either 1/4" or 1/8" collets, so it's versatile and easy to use.
I have a Foredom K.2272 tool with a 4' flexible drive to use with small wheels like a Dremel, but it has more power and the flexible shat allows me to get into really tight places and leave the drive motor out of the working area. I usually keep it hanging above my work bench with the drive cable down to keep it handy, and it gets more bench use than portable use, but when I need something really small it's the best. They're about $330 now, but well worth every penny.

Yes, DeWalt makes the DC411 cordless 18v angle grinder.

I have a Milwaukee die grinder (electric) and not the one shown in post #6. Mine is smaller and less expensive. About $130.00. With a toggle switch (don't like the paddle switch), about 20,000 RPM. I use 3&4" x .035. I can easily fallow a scribed line.


Silicone caulk has it's place, but not every place.

This is probably beyond the scope of the conversation, but I'm getting ready to cut several 4" strips of the 38" wide X 5 rib steel roofing to cure a contractors mistake (he laid the roof panels too high, causing rain to run down the inside wall of my $50K building). I plan on using a 10" abrasive metal blade on either my Table Saw or Radial Arm Saw to do the cutting. I've tried cutting this stuff with smaller (7" Dia X 1/4" thick) blades, and it seemingly took all day just to make one cut! With 60' of material needed to fix the roof, and winter coming on, I want to get it done quickly! the blade I intend to use is 10" X1/8" for $4.79 @ Lowes.

And Yes, I'm going to move the saw outside, wear my welding helmet, a fireman's bunker coat, Welding gloves, combat boots; have a garden hose, and 2 fire extinguishers (type A & Type BC) and an air pack available, with my guardian angel on a 1/2 second response time status, I think I should be able to handle the task.

Aren't you the least bit worried about running the electric tablesaw outside in the proverbial rain storm ? You should at least wear 20K volt linemans rubber gloves inside the wedling gloves, a full wetsuit with booties, and even think about a gfi adapter on the cord. That is the minimium, you could go the extra steps and be safe if you don't want to live on the edge

Not in the least bit, I was in the Navy and I once saw my Mother-in-Law naked; Nothing can shock me now!!

These are expensive, but you get what you pay for:

this thread is funny, but like everyone else said, safety first! I wear a hat and safety glasses even with a face shield.

I use a 3" cutoff air tool for smaller things, I mainly use 4.5" harbor freight grinders with good wheels. the hf wheels shatter and explode regularly where the good ones actually wear out over time. I also have a 7" hf grinder that I use to knock down frame welds, thick material shaping, edge bevels, etc. to save wear on the 4.5" thats usually set up with a cutting disc anyway. the only good thing about the hf grinders, the hf store is only 2 miles from my shop.
