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

In this video i will show you which blade / disk to use for cutting plastic, concrete, tiles, metal and also grinding. The four main angle grinder blades / disks in this video are the most commonly used and work very well. The cutting disk is generally used for cutting most types of metals however it can also be used for cutting plastic as shown in the video. The diamond blade / disk is can be purchased specifically for cutting tiles or with the turbo diamond blade for cutting into concrete, clay, brick, cement and also stone.
Special thanks to Devin who asked if plastic can be cut using an angle grinder.

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.

Can I just perpendicular to your cuts to make it easier to knock down after?

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.

[@somytony9713]

Never trust Abdul.😂

[@contessa.adella]

Depends upon the design of diamond disc. Continuous smooth rim are meant for tile and porcelain and don’t chip the work. The continuous rim with a fluted design as in the video are meant for concrete, brick and pavers…they CAN be use on tile, but might chip. Segmented diamond discs (ie. has slots around the rim) with a rough coating of diamonds are usable on steel, although not as fast cutting as a bonded fibre cut off disc as in the video. Don’t use these with aluminium as the soft metal will clog the diamonds.

[@chrisgraham2904]

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.

[@aventurandoconfredy]

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.

[@williamtente893]

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.

[@robg3545]

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 kzbin.info/www/bejne/Z4WpmqaDmKmlfpY whole show everyone how to do things properly.

[@RADCOMJ1]

I am an angle grinder noobie and I thought that as soon as he started cutting....wheres the guard

whats for wood ?

[@honeykaetan9416]

Hi Bill, how bout for the wood?

[@sandrapalomares4775]

I found the angle grinder to be the most horrible tool for cutting wood of any type, size or thickness. It burns it and is extremely difficult to make good quality cuts with. If you aren’t careful or you have one of the more powerful angle grinders it can damage or leave undesirable edges even on metals if they are of the non ferrous kind such as aluminum or copper. Also cutting pcv or plastics can be dangerous due to the grinder causing the material to melt and then slinging off the hot bits of materials and hot plastic can cause serious burns to skin. So be safe and cover your skin and wear face protection.

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 had a lot of old pipes and rebar to cut up and from what I read kzbin.infoUgkxPDBfLu68o58Aw85O_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.
