That's why you don't take the guard off when using the cutoff disc, numbnuts.

I heard about a guy who broke his jaw with one of them. trying to cut an 8 inch pipe on a scaffold, the band saw broke so instead of climbing down 15 feet to get a different one he decided to grab the 7 inch grinder with a grinding wheel and cut it that way. he got about 2/3rds through, the pipe flexed where he was grinding it out, locked up the disc, worked itself free, sent it flying back at his face. lost 7 teeth and fractured his jaw in 2 places.

Couldn't pay me to use an angle grinder to cut shit.

>>1890779
Fucking pussy I use a grinder every single day for years and never had a serious accident

>>1890757
I've had that exact pissburg electric harbor freight 12 dollar grinder disassemble itself in my hands on 3 separate occasions lel

can someone rec a good angle grinder? i need to cut a piece of tile but would think it would have use for other things down the road. thanks

>>1890799
Depends on what type you're comfortable using, bru. They come in different wheel sizes. Most common is 4-1/2", and since you don't seem to know grinders, start there.
The main thing is that there are three main switch types for grinders: sliding switches, paddle switches, and triggers. I prefer sliding switches. They lock in the on position until released. Paddle switches are kind of like triggers, but they take up the whole grip, and they have a safety mechanism that keeps them from turning on unintentionally; grinder only remains on as long as the paddle switch is held. Triggers are self-explanatory.
The only other things that matter are amp rating, and whether, or not, the speed is adjustable.
My opinion, go with either makita, or milwaukee.
Grinders aren't expensive, especially since 9 times out of 10, you're gonna be buying a corded one. Something like a grinder, that's meant to just run and run, beats the hell out of batteries--makes them overheat. So, why cheap out on them, you know?

>>1890779
Pussy. I get that grinders aren't the right tool as often as people think they are, and I also am against taking the guard off. But, just being unwilling to cut things with a grinder, even when it is the right tool, and when done right, just makes you a baby.

>>1890929
thanks!

>>1890944
I've used them, for anything I do I feel like I can go faster furiously hacking away with a saw. If I get a chainmail cock guard I'll feel better

NGL anon an angle grinder cuts through metal fast af with the right cutting blade
I'd take Aprox 20 sec or less depending on how incompetent you are.
You'd likely be off & away on the bike before people really could stop you or figure out the source of the noise

He might be one of those rare guys who has plenty of money but still likes to /diy/ stuff, so he buys some stock, cuts his pieces, and tosses the extra. Unlike most of us who have tons of scrap shit we will eventually use about 5% of.

Do you believe that buying a 12$ grinder from harbor freight is hard?

>>1891686

I have like 10 grinders, corded and cordless
This m18 9 inch grinder with a 12ah battery was like 500 dollars lol
It kicks ass too

>>1891690

>>1891700
Buying a 12 dollar grinder isn't hard but 2 500 dollar grinders is definitely not as easy
And why would you unless you use them every day.... oh wait I do lol

>>1891686
>>1891714

>>1891781
I made this with a grinder btw, it's the most versatile tool to ever exist

I don't understand le exploding cutoff disc meme, I've spent the last few weeks on the grinder all day cutting up mesh sheets. I have had shitloads of cutoff discs disintegrate but they never ever throw giant rape shards out.

>>1891799
It usually happens because retards take off the guard and use larger discs that aren't rated for the higher RPMs. This dumbfuck in Engineering when I worked for Milliken almost killed himself when he did just that and the blade shattered then caught his arm and slit his wrist all the way up to his elbow with the stray shark toothed looking shard that was left still attached to the hub. If an ex marine hadn't tourniqueted his arm he would have been dead before the ambulance got there.

A major grain company in the US has recently adopted a rule that anyone within 10' of someone doing a task that requires extra PPE (like a face shield for grinding) must have the same PPE on.

So, if I'm holding a ladder for a guy who's wearing fall protection, I guess I have to have fall protection too.

Yeah, good luck on enforcing that with a bunch of knuckle-dragging millwrights.

This is a direct fucking result of WAH. These pencil-necks who have never spent a minute in the field anyway are "working" from Mom's basement and just dream up nonsensical shit.

>>1891525
Sorry about that. I have CSS code that hides names and tripshitcodes so I had no idea it was one of the village idiots.

>>1891799


Like >>1891855 said, it's mostly a problem with using bigger discs than what the grinder is rated for.
I've had a bunch of discs break from binding, but when that happens, it just breaks, the pieces don't go flying.
If the pieces go flying, it's because the centrifugal force was too much for the disc.
Another reason it can happen is using discs that got wet, or slightly damaged, weakening them.

Daily reminder that pretending to be retarded makes you retarded. Sharpenel can change direction.

Look up ANSI z87.1
>you can figure this out
Also, hearing protection is also a good idea

>>1890799
Whatever you do, use thin cutting discs. I don't know why they even bother selling anything wider than 1.6mm.

>>1891883
That's a little extreme, but if you're using tools like grinders, and you aren't wearing PPE, then you get what you deserve.

>>1890799
>cut a piece of tile
just borrow one.
don't buy a tool for literally a single use.

>>1891375

>implying any NPCs are going to care enough to stop you

Grinder would cut through a lock so quick I'm guessing most people would just think you were fixing something on the bike or something before they figured it out. A hack saw would make less noise but it's pretty obvious what you'd be doing.

>>1892689
I wonder what the percentage of jobs done with bolt cutters are criminal in nature.

>>1892745
I have a little fishing boat chained/locked to a tree by a little lake. My cousin wanted to use it and I wasn't around to give him the key, so I said he could just use his bolt cutters.....bastard cut the damn lock.

I only use a brushless battery grinder and only when another tool isn't suitable. I'm a builder so that's completely sufficient. Brushless grinders have an automatic anti kickback feature that operates in a split second and I can personally attest to its effectiveness. Plus an 18v grinder is a lot less powerful. That helps.

I hate the bloody things. Most dangerous tool I own imo. At least with a drop saw or table saw you just have to keep away from the blade, the blade doesn't come to you. And a skillsaw is safe enough too of you aren't using it like a retard. I don't own a corded skilly anymore either, because I have a cordless one that's as powerful and again, blade braking and anti kickback. It makes a difference.

>>1892307
Metabo = shit

anyone ever use those new chainsaw bladed discs? those things are great

Sure thing tough guy. Surprised you're not using a handle.

>>1890757
That's why we shift that little spark-guard panel around to the angle where it catches sparks flying up at you, and directs them down.
So you just lightly burn the skin on your leg and leave a funny scar pattern on it, rather then perforating your eyes or inhaling the sparks.

>>1891883

The point of rules like this and the procedures on big sites is not mainly for decreasing the amount of injuries. Its making the companies less liable for compensation in the event something happens.

They can always blame the worker for not following this and that set of rules.

Yes. The EHS dweebs have lost whatever sufficed for their minds. EHS is where they send idiots who are too incompetent to be in HR.

Damn my nibba, I didn’t realize how much bigger the 9 was compared to the 5. I was gonna get the 9 to supplement my 5 the other day but thought it was unnecessary. Now that I see it, I don’t think I would want something that unwieldy.

>>1893189
Yes, most terrifying tool I own, honestly. If I said they went through wood like a hot knife through butter I'd be understating the case. A newly sharpened chain goes through wood with literally no resistance, it's incredible. However makes my anus pucker every time it grabs on the wood and I get a mental image of it going underneath my face shield somehow and eating straight into my jaw. Fantastic for removing shitloads of material quickly, followed by a burr disk to even it out.

i almost had one of these on my legs. had been cutting for about 45 mins and was tired. cut an overhead branch and it fell with the saw stuck in it somehow and fell right on my thigh. cut through my pants and just barely kissed me with a 2 inch long scratch.

>had prescription googles on
>figure that would be enough
>Go to cut a small bit of square pipe
>somehow still get a bit of hot metal shaving in my eye and I have no clue how
>I now use a full face shield and googles when cutting with a angle grinder

Hurt like a bitch but my eyesight was thankfully fine.

Why is it so hard to find corded brushless angle grinders?

>>1897567
Das habe ich schon gemacht. Das Fett war nur noch in den Ecken und hat die Zahnräder nicht mehr berührt.

Aber ich meine die Schleifscheiben habe mal was gelesen das die ein MHD von 2 Jahren haben.

>>1897677
Because there is no point in making them. When you're tied to the grid, you can use as much power as you want and there is no point in using a more complicated motor drive system to save that little bit of power. Brushless is a bit better for cordless but is not needed for everything.

>>1897677
>>1897965
brushless more complicated?
brushless is far more durable but you need 3 phases for it.
Fein makes some Variable frequency driven BL grinders. they use these in ship building or somewhere you have to run a grinder all day.

>>1898147

>>1890757
Dude, just look the other way and you're fine

>>1890799
Buy a tile cutter. i got this one at harbor freight, unfortunately, they have sold out. I use it to cut wood, metal, etc.

>>1891883
Quit your bitching and put on your safety gear.

>>1893189
I bought one, and am using it with the tile cutter I have. I didn't think there was any dangers associated with it.

>>1897543
As long as they stayed dry they should be fine. Just don't be a dirty nigger and take the guard off and/or try to force the disk into the workpiece. Applying pressure while cutting is 90% of the reason they kickback and bite people.

>>1897677
because the advantage of low speed torque seems pointless on a grinder

>>1890779
Works fine if you aren't stupid and "see" the work as a process.

Stay out of the plane of rotation.
Use the fucking guard.
Hold the grinder with both hands.
Cut such that you don't pinch the cutting disc.
Cut such that you don't sideload the disc.
Do not force the disc (hold the grinder gently and let the disc float and do not load it down).
Mimic industrial cutoff saws and move your disc gently back and forth in the cut which widens the kerf a few thousandths of an inch and makes a shallower cut than the arc of the disc edge reducing jamming.
ALWAYS know and consider theory of operation of every tool you ever use no matter how simple they appear.
Wear a face shield, gloves and glasses. I have full PPE at home too. Many pros get hurt at the house because they imagine PPE isn't worth the cost.
Don't wear loose clothing.
Direct the sparks away from your body not least because fragments go that way if a disc fails.

I and many weldors have made thousands of cuts safely with cutting discs. BTW we also know the most vicious flesh eater is the flat knotted wire wheel (not the cup style). Those motherfuckers are brutal.

The ideal cut position is where the disc would be free to fail and still could not hurt you, like the ideal rigging lift can fail and hurt no one. Always plan for "safe failure'. Or not, since I don't work with you.
