Which angle grinder blade / disk for concrete, plastic, tiles and metal 

Thanks for this video. I went to the markets and was told by a man named Abdul selling discs, he sold me the diamond one, and told me that it can be used for metal and everything else, until I asked another stall that sold grinding discs, and was told it was for stones and tiles. Abdul lied to me, and I asked for a refund and he refused to give me back my money. He then lied again, telling me to change it to the tile specialty bit which is for tiles, saying its for steel. Lucky I lost my temper after not wanting an exchange and called the manager of the premises to help me get my money back. This video has shown me exactly what he tried to sell me.

Do not use a cutting disk for grinding even if it's just light grinding it's very dangerous! If you are lazy to change your disks then just get yourself another grinder that always has a true grinding disc mounted.

To be 100% honest, this is super helpful bro, thanks a million. Watched it, tried to cut pipe & worked perfectly. Thanks

Straight to the point video, thanks so much!

Learned a lot in this quick video, very nice...It goes without saying that if you are not comfortable using these, put on the guard.

Your living on the edge if your operating a hand grinder without the guard, especially with the thin "cutting disk". Never use the cutting disk's side surface to grind or apply any side pressure to the disk. Always clamp the material if your cutting deeper than a quarter inch into the material, like the square tube or pipe -- any binding can shatter that disk. Google : "Angle Grinder Accidents" if you need a visual reason to respect this tool.

Excellent no-fuss demo. The stuff I've seen my now 78yr-old boilermaker / welder father do with a grinder would horrify most people!

This is a great video to learn how to use different types of discs and how NOT to use a grinder (no epi and guard ) . Please note that this is one of the most dangerous tools in any shop, always expect the worst.

to be 100% honest... nice job bro 100% honestly

If you’re grinding, use a specialized grinding disc or if the material falls for it an abrasive wheel. Why? The material and design of the disc is specific to that application. A cutting disc is not designed to handle the compressive and shear force exerted upon it during the act of grinding. This is an incredible safety risk not to mention you’re not going to get as good a result that you hoped for and your consumables won’t last nearly as long in comparison to using the right material for the job. I won’t even get into the safety issues because those have been covered in hundreds of other comments.

You answer my question with this video! Thank you!!!

Thank you for this demonstration !! Eye opener !!! Awesome Bill !!

Nice straight and fast cuts! Beautiful 👍

Good video, thanks for making. Short and sweet. I am being 90% honest

Use guard and gloves if you're going to teach

Perfect video i needed before i went to the store thank youuu

Thank you thank you. A newbie to grinding, your enthusiasm spurred me to hope. Take care out there.

Loved it. Thanks!

Mate, you are full of energy, i mean positive energy. Great video.

Brilliant mate. Thanks for explaining this for us noobs. Video was short and to the point. Thanks

Straight to the point. No bullshit. Thanks mate.

Good man. Great informative vid. And straight to it (i.e.No long intro or bullsH!t ) Worth a sub

Great video, thanks 👍🙏♥️

Very helpful!

My mate who barely ever uses his angle grinder had a disc break without using a guard and it was inches away from making him infertile... don't mess with that shit man

Perfect

Cheers Bill ..the info was exactly what i was looking for!

EXELLENT INSTRUCTIONAL VIDEO. Thank you Bill.

Nice from india

Hi Bill, can you tell me which blade/disc to use for cutting fiberglass? Im repairing a fiberglass pool.

OMG, you used '' mm '' and not weird inch fractions :))) God bless you !!!

No guard no gloves and applying pressure to flat part of a cutting disc is very dangerous due to them not having reinforcement and being so thin please show how to use safly even though we have all done it at some point knowing it's dangerous will hopefully prevent a accident

Hello Bill. Great video. Could you please explain what each disc measurements mean? For example: Glass cutting disc 100x20x10x2.7 Thank you

I have that same cordless Ryobi angle grinder. You really need to state up front that this grinder is very low power, has no trigger lock, and spins at about half speed (which would be 1/4 the kinetic energy). A corded angle grinder that spins at the full 13k RPM and has a locking trigger for prolonged use is incredibly dangerous and should never be used like this. I didn't understand the safety hype until I got a corded grinder. What a scary tool that thing is.

2:37 - 3:55 Holy crap. I see people do this a lot but for a tutorial video this is dangerous. You don't want beginners seeing this as a right way of using a grinder

you can always tell the ones who use a grinder all the time..we remove the guard and handle LOL. good vid fro the most part

PPE is helpful in case of an accident. Let's be cautious in the way we handle our power tools. 😊

I like this guys Mexican accent makes this video more enjoyable. Almost sounds middle eastern.

If i use diamond disk( lapidary disk) can i use this machine for cutting or grinding agate and Quartz? Is it strong enough? And easy to control?

Bill, put that grinder back in its box until you get protection for your ears, eyes and hands. Oh and put your material in a vice while you're at it. I'll come back in 6 months and count your fingers ;-)

Great vid! Very informative, TY.

Hello do you have a link for that grinder and the blades for cutting hard plastic and hard rubber hoses???

Hi. Many thanks for the great advice !!! I have 2 doubts I can't find an answer to. I've just bought a Makita M9507B 115 mm. Its spindle is 21.16 mm. Do all makes of 115 mm discs have this same spindle diameter or do I have to get only Makita discs? And here's another query: I have been given a smaller diameter Bosch disc, in fact, 110 mm, whose hole is greater than 21.16 mm. So, do spacer washers (shims ?) exist so that it would fit my Makita snuggly and prevent it from wobbling, perhaps dangerously ? Perhaps there are tapered locked nuts to take up the space? I'd be very grateful for your guidance.

i have a small sears grinder with a cord can i use it to cut plexglass a thin pce want disc can i use thx you

Never use the cutting disk to grind wth bro

You shouldn't remove the angle grinder guard.

Can you use the diamond disc to cut rusty bolts it's only available disc i have?

My Ryobi angle grinder P4221 say to only use type 27 disc and never use a type 1 disc. Most of the blades you recommended are not type 27 but are type 1. I am trying to find a type 27 cut off blade. Does anyone make them or is my angle grinder basically just for grinding / sanding?

Hi Bill. Loving your videos - straight to the point with no bullshit. Can you do a video on how to remove and install an electric oven??

What disk is best for fiberglass?

You shouldn't grind with cutoff disks, they are never meant to take side loads. Also wear your safety equipment

I also use the fine cutting disks to cut pvc! It makes very clean cuts!

Can you use masonry disk to grind concrete?

I had a lot of old pipes and rebar to cut up and from what I read ru-vid.comUgkxPDBfLu68o58Aw85O_J-zIFfjJARBhp-3 this would be the tool for the job. Since I had never used one, I watched a couple of youtube videos and I'm so glad I did. Some really good safety tips, which I followed, and this tool did a splendid job. One good thing to know is the weight of the tool puts just about the right amount of pressure on the metal I was cutting, so I didn't have to use a lot of pressure, which is more likely to jam the tool. It made fast work of my job.

Love your videos Bill but just one thing re the cutting discs....They should never be used for grinding, not even light grinding...they are prone to shatter and should only be used to cut.

No guard? Will give you frisbee and hot chips

Bro really no gloves No Guard, I bet you’re not even wearing Eye protection or Face shield. And don’t give me that crap that it gets in the way because it doesn’t FYI grinding wheels whatever you wanna call them have expiration dates ! they could shattered in your hands just be careful my dude I seen some fucked up accidents with angle grinders at work

Wow. Youve gotta be more careful when trying to teach people how to use a dangerous piece of kit like a grinder. I can see youre trying to be helpful, but youre like a "what happened next" safety video. Theres no guard on the grinder. If the disc bursts, it'll cut straight into you, jagged material at hundreds of mph. Theres no handle on the grinder, which would give you extra control of it. You havent secured the piece youre cutting, so youre holding it with one hand, meaning you dont have full control over the grinder if it kicks. Also you will never get a straight cut. Youre not wearing gloves. Youre not wearing thick clothes. Youre not wearing a mask. Your work site is so untidy that those sparks are going right into your shelves of junk into who knows what. Lets hope theres nothing flammable like solvents in the spray bottle near your feet. If theres stuff around your feet like the spray bottle you havent cleared your work site of stuff to trip over while you are using the grinder. And all thats before you tell folk to use the cutting disc to grind. Really suggest you watch this guy ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-1TFisMcDrH4.html whole show everyone how to do things properly.

No PPE anywhere to be seen , wow !

How about segmented diamond blade

Hi Bill, how bout for the wood?

Searching whether metal cutting disc can also cut brick, i found no results. I tried it and it turns out it can. Wondering what other stuff is possible...

Thanks for the info but we shouldn't use the cutting disk for grinding especially metal.

...and preferably use the disc guard.

whats for wood ?

This guy doesn’t use the provided safety guard. Dangerous. Don’t. Always use the safety guard!

Where I can order that blade

Yeah, there are so many errors using the grinder in this video: 1. no handler mounted 2. no safe guard properly installed 3. no PPE such as gloves 4. the cutting disc is mistakenly used as a grinding disc

That was informative. I don't understand why someone gave it a thumbs down.

where is ur protective guard?!? omg

Beau Ryan bloke

What about aluminium ?

is there a disk for concrete and metal

What is the size please

Put the guard back on

Why are you yelling at me ??? I feel threatened !

Wrong when a potential traumatologist patient tries to train to work ..!

Why use a sander without protection?

Dont use cutting disc like that its wery thing and it will brake like that and you are not using a guard over the disc use a flap disc or grinding disc

Plot twist: How not use an angle grinder.

no blade guard???

Cutting metal disk can also effective on wood?

Very bad and dangerous advice saying that you can use a cutoff disk for grinding!

Highly suspicious and very unusual if anyone kept emphasizing being 100% honest...

Cutting disc is for cutting not for grinding.. Its dangerous

bolehkah anda berbahsa melayu kawe x pehe demo kecek gapo..

He is using it in a wrong way

No ppe

Flange

No safety..

Put your guard on your tool. Very foolish.

GOOD TEACHER

Too much talking,, boring

Wow !!!!🤬 Holup bro Did you just use your cutting disk to grind ????? Never do it even slightly. You can loose an eye or couple of fingers. Lot of dumb people did it and regret it. Just grind with a grinding disk and cut with a cutting disk for god sake. NEVER !!!!!!!

Really bad video for a newbie especially. Encouraging very dangerous habits.

PPE is helpful in case of an accident. Let's be cautious in the way we handle our power tools. 😊
