[@gordonpeirce5967]

Hi, firstly thank you for the great safety aspects, as there are many people just starting to use Grinders. I have looked into the correct way to put on a Steel cutting disc and all manufacturer's have avoided the answer. As I know that a disk can chip if used incorrectly, I have to agree with you that the washer must go on top where the locknut fastens it, this removes the tension on the fibres under the locknut when tightening. Well done and thank you for talking about safety as this will help beginners a lot.

[@thestonecraftingworkshop7490]

you are very welcome, thank you for taking the time to leave such a constructive comment, cheers!

[@timthorne3412]

Lovely presentation...just bought my first angle grinder and this has given me the confidence to set it up safely...well done mate

[@steveoranges1960]

It's really irresponsible of manufacturers not to include crystal clear instructions on these things. They have lots of safety warnings but they neglect to mention how *exactly* the disks and wheels are supposed to attach on

[@thestonecraftingworkshop7490]

That would be nice wouldn't it? But then no-one would watch my video! Thanks for watching.

[@cromyjr1592]

Or they put drawing-heavy manuals with as few words is possible, and where every drawing is using only one line thickness and words are chinglish or japglish (I'm looking at you, Makita)

Excellent presentation. Just taken delivery of Makita GA9071x1 230mm. It will pay for itself in one job for daughter's new house. Was going to get a more basic 230mm grinder but decided the extra safety features warranted spending more and, as she said, still cheaper than paying a handyman. Label on Duro Diamond Blade says spin anticlockwise so - label down. Permanent marker arrow to remind me. Been using a lovely Bosch small grinder for years without knowing why I should install blade to spin clockwise or anticlockwise (label up or down). Only gripe is 110V is rarely available now. Replaced by cordless. Had to get 240V. I'm DiYer so don't have to abide by site rules but, as the saying goes, "Voltage kills, not current"

[@thestonecraftingworkshop7490]

Hi, never used Duro blades, all the diamond blades I have seen have the direction arrow printed on the label side and fit label up. That said with diamond blades especially I think you can over worry about direction of spin, I have often reversed the direction of diamond blades to sharpen them up with no problem. Take care,cheers.

[@danielmabuya7070]

Thank you for your excellent presentation. I am one of those experts that is so good in loosening the screws to dissemble any type of machine, but bad in assembling or connecting back the same machine.

[@trekzilladmc]

Terrific video! Probably one of the best ones I've seen on KZbin. Most other videos are just a few minutes long and don't thoroughly explain it in the detail you have. I've always thought the same about the center metal ring. My logic is that it acts as sort of a "washer" for the retaining nut to slide against. One tip I'd like to add is if you have a habit of misplacing the spindle wrench is to drill a hole in the end of the handle and nylon zip tie it to the cord with just enough tension that it'll still slide but not slip off the end of the plug.

[@thestonecraftingworkshop7490]

Thank you for the kind comments, it is really appreciated. The tip about fixing the spanner is a good one, if only I was that organised! Thanks again!

[@thestonecraftingworkshop7490]

You are welcome!

[@lenfana]

Thank you for an excellent video, which I found to be clear and concise. The presentation is first class, and so many of my questions were answered. One particular aspect that I appreciated very much was that you didn't just say "do this", or "do it this way" and leave it at that - you also explained the reasons why. So many instructional videos and instruction leaflets tend to omit giving the reasons why a particular course of action should be taken, and pleasingly, you certainly didn't do that - the difference between being an educator and an instructor.

[@thestonecraftingworkshop7490]

Thank you!

[@jeisonsanchez4842]

Thanks for this video. I bought my first angle grinder in 2016 and used it a couple of years ago to cut into a plaster wall. Super messy but it was the only tool I had that could get the job done. I used it today with the twisted wire brush wheel for some rust removal. I had the same question about which side goes up. I tried both ways and it only fit properly with the nut side down. I was really concerned about safety as I had read that the wheel can shoot out pieces of wire and debris. I’m glad I went with a face shield instead of just safety glasses because when I was done, there was a bunch of rust particles on the shield.

[@thestonecraftingworkshop7490]

Brilliant point! wearing a face shield or goggles is essential and never a bad idea! thank you for making the point. Cheers PS: I would think that an anglegrinder is too fast for this task, a sander/polisher runs slower and might be safer with less debris flying about. take care.

[@poohpot4462]

Excellent video thank you so much for doing this. Really appreciate it! I think all user manuals should come with an accompanying video like this that the customer watch.

thanks big time for showing each STAGE of how to fit new blades... i felt in safe hands :) i've worked with many power tools, saws and all sorts (maintenance work), but when i heard grinders spin *twice as fast* as circular saws, i took a deep breath, especially since grinders lack a guide (i know these can be made, but i don't have the metal working skills, or time really, to do that). if anyone's fresh to grinders (like me), please watch the pro-guides on youtube including this one... at 5000 rpm plus, this thing could take off a finger before you blink, and send out shards that will seriously damage your eyes... you only get one pair... wear grip gloves and proper safety goggles ... i am gonna say this again: wear grip gloves and safety goggles , and clamp the material to be cut [you'll thank me one day] peace x

You are my hero, I couldn’t figure out up or down for my recessed stone blade, as I’m new to angel grinders having only ever worked on far smaller rocks and glass sculptures until now. So grateful 🥰

[@thestonecraftingworkshop7490]

Hi Mel, thank you for the kind comments. Time for my old man grandad nag - please wear safety glasses or goggles and a good dust mask all the time when using an angle grinder. As you are new to these tools have you considered using a cordless angle grinder? They are lower powered and therefore safer to work with. And you can use these with a water feed without risking an electric shock. (though this will invalidate your warranty ) I love using my Parkside one for carving and finer stone cutting. Enjoy your carving!

Thank you sir... definitely a valuable video. I am also new to angle grinders and my main question was orientation of the flat cut-off discs. I actually decided to go with the type 27 cut off discs because they fit better inside the guard. And of course those are orientated the same as the grinding discs with the depression towards the machine.

[@reaper060670]

i JUST BOUGHT 2 MORE aNGLE GRINDERS AND i ALWAYS LEAVE THE BLAde with the label not showing. It works for me but I'm not sure if it's correct. I have 3 grinders now but I do regret not buying a 230mm one.. I do a bit of metalwork now more so than anything else so to have 3 is a godsend bcos now I can work faster and not have to keep changing blades to flaps, etc. Thanks for the content my man. Always very informative..

[@thestonecraftingworkshop7490]

Thanks for the comments, label up or label down is really not critical, even on diamond blades I often turn them the "wrong" way when they lose their cutting edge and they start to work again! Glad you are enjoying your anglegrinders, they are my favourite tool though I don't have so much use for them nowadays. Take care!

[@jeremykemp3782]

Good explanation ., well done mate. Back in the day the arrows used to point in the direction with label facing down, that's how that got stuck into traders brains. But not the case anymore, just use your common sense on every blade you use depending on the contours of the blade.

[@thestonecraftingworkshop7490]

Thank you!

[@maxpsanchu7386]

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.

Anyway, I went back to the store and got the charger and battery, a 4 amp. As for the wrench I'll use my vice grips for a while and get the wrench off amazon. Thank you for the info.

I just bought a new grinder and I am having trouble removing the locking nut. It turns out I have a wrong size for the unlocking key. Even though you advice of using getting the bolt loose seem practical, my bolt is solidly stuck in place. Your advice for not tightning the locking will be used next time. Thank you for your expertise.

[@thestonecraftingworkshop7490]

Hi, if you can fit just one of the lugs on the key wrench into a hole in the nut the other lug will seat onto the rim of the nut and can be used that way (does this make sense?) The main reason nuts get locked on is when the blade is not tightened enough in the first place, the machine when started spins the blade into the locked position too hard. best of luck with this.

Good morning. With all these years of experience, how do you tackle kickbacks? Your explanation is excellent ...

Hi, I always hold the tool in a very firm grip. well braced with legs apart for balance. I cut standing behind the tool out of the line of sparks or dust looking over the machine to see the blade. Also I always try to cut with the subject on the floor. That way if the machine kicks back it simply shoots back into thin air, not me! Hope that makes sense? Take care.

Also - a great, easy way to make an angle grinder spanner that fits all; take an old adjustable spanner, drill holes the same size as the holes in your grinder locking nut, through each jaw of the adjustable spanner. Find some nuts and bolts that fit your grinder nut, and bolt them into the holes you've drilled into your old adjustable spanner. This way you always have a grinder spanner that will adjust to any size grinder. :) I've had and used my home made one for the past 15 years.

Great Video, I like your voice! I had a feeling that I have been using my diamond disk the wrong way. It’s because of the flat cutting wheels I use it with the label up (or down when you are putting them) because I grind with them a little and soft (no that much pressure). Thank you.

Not 100% sure what it called but it kinda looks like a bunch of small pieces of sandpaper all lined up. It keeps spinning about .15-.20secs after the Grinder stops. Normal?

[@thestonecraftingworkshop7490]

Hi, I'm not sure about this, it sounds like you are using a flap grinder, I have never had occasion to use one of these but I am pretty sure it should not continue spinning. It sounds like the boss nut is not gripping the flap wheel. If you press the locking button can you still turn the flap wheel ? Can you tell me the model of your grinder and I will have a look.

[@J.T.19134]

@@thestonecraftingworkshop7490 it is a Flap Disc. I just looked that up. I bought a $39.99 Metabo HTP G 12SR4. For Sanding and smoothing out edges and whatever, I watched a video on it.

I'm an MMA Fighter who has alot of free time, so I originally got into Electric, and Circuit boards, until one day I thought everything was connected properly, must of had wired crosses plugged in a cord to a homemade lathe, both end popped, and Blue my electric box right out of the wall.

[@thestonecraftingworkshop7490]

@@J.T.19134 Hi again, I have just looked at the online instuctions for your grinder. It is a surface grinder rather than a standard anglegrinder which is normally for cutting. This means it is designed to take thicker grinding discs as opposed to thinner cutting discs. Looking at the drawing of the fitting washers it looks to me as though the backing wheel has a deeper raised section than a normal anglegrinder to accomodate the thicker wheels. I think you are buying thinner cutting discs and not proper grinding discs, these can also have recessed centres but should not be used for grinding. This would explain why the wheels are not tightening down. Take care ! All the best!

Recently watching your videos, realising the importance of adequate power for stone cutting, i have a question. How much power does one need in an angle grinder for cutting through stone? Is 950w enough? Recently wasted money on a mini grinder with inadequate power, don't want to do it with a big one too. Thank you in advance, your videos are great, helped a lot. Cherrs.

[@thestonecraftingworkshop7490]

Hi, it depends on the stone and the type of blade and how deep you need to cut. In theory even a cordless angle grinder will cut through stone or granite if you give it time rather than push the blade too hard. It sounds like you are trying to cut a lot of material fast, I would have thought a 950 watt tool plenty powerful enough for a 5 inch blade. If 5 inch is cutting deep enough for what you want. In fact blade size is more important than the wattage, a bigger blade turns with a lot more torque and power. When I am taking a lot of material off I will use a 9 inch Angle grinder but that does take a bit of experience to control and I have been doing this a long time. Take care and I hope this helps.

After seeing 3:40, I realized that the backing plate on my 2ndhand angle grinder has a recessed area which is smaller than the spindle flat sides. So the backing plate is not locking in place. It is just riding on the spindle. It is surely the wrong backing plate for my angle grinder. Thank you.

[@thestonecraftingworkshop7490]

Hi, the backing plate should have a wide slot that sits on a matching raised part of the spindle to stop it spinning. I assume you have not got this, Best of luck!

[@malcolmjames7388]

Great video , Thanks.....I have been told that all these disks have a expired date on the centre of the disk, Where the washer is

[@thestonecraftingworkshop7490]

Yes, correct, some discs do have an expiry date. I have no idea why this should be, I have used discs decades old with no problem. The only time I would be concerned is if the disc got damp maybe? The discs are resin bonded silica carbide, nothing to rot or degrade there unless those discs are made with inferior resin that degrades in sunlight? Perhaps a disc technologist can enlighten us? Thanks for watching and for the interesting input, cheers!

Great video Sir, but I've been told by many manufacturers that for Abrasive Slicing Discs that only has a RingSide (support washer), it shall ALWAYS be PRIORITISED to Face Towards the Backing-Flange (that is recessed upwards as standard) and thus the Non-Recessed(FLAT) Locking-Flange that will be screwed/pressed against the Abrasive Side DOESN'T Require the RingSide (support washer). They further explained that ALL ATTACHMENT including Abasive Slicing Disc that will 'meet/face' that 'recessed Backing-Flange' MUST BE RIGID. That is why a RingSide (support washer) is designed on every Abrasive Slicing Disc. Its to be Used AGAINST that Backing-Flange. All other attachment such as Diamond Blade/Multi-Disc etc which is ALREADY RIGID Both Sides have no such issues and are to follow their Arrow of Rotation instead. Hope this information helps...🙏

[@spirit3soul]

Clarification needed. At apx 14:21 you put on a depressed blade, yet you didn't have the nut (higher middle part) going down, but did on the next depressed blade. Sorry, if I missed an explanation of why.

[@thestonecraftingworkshop7490]

Whether you put the raised boss down or up depends on the thickness of the blade, on thinner blades the nut won't tighten up if the raised section is down. Hope this helps.

[@timwilcox960]

Clear and comprehensive - good job. Having just bought a new Makita angle grinder, I've watched three videos prior to yours and none of them address which way the blade/disc should be fitted. One even said: 'be sure to put it on the right way' - without any explanation as to which way the 'right way' is! :-) Having fitted an Abracs diamond blade, I assumed (correctly) that it had to rotate in the direction of the arrow on the label. However, I noticed there was a lot of play in the blade left to right, which would make accurate cuts impossible. After watching your vid', I realised I'd put the locking nut on the wrong way around (but the right way had I fitted the 6mm matal grinding disc supplied with the machine). Having flipped it over, the blade is now tight without any play at all. So, thank you kind sir! :-)

@@thestonecraftingworkshop7490 It was helpful TODAYI slapped a cutting wheel on with the label out-it seems like it should go that way, for the manufacturers name to show, if nothing else-but then I checked the arrows. I had it backwards. 👍

[@jameshalligan8775]

Whats the best blade,for cutting sheet plastic??

[@thestonecraftingworkshop7490]

Hi James, you've got me there! I have never had occasion to cut lots of plastic I am really a stoneage man! I would try one of the newer thin carbide or aluminium Oxide blades or perhaps one of the new multi material blades that are appearing in the shops. They seem to have a thin coarse diamond edge. I am pretty sure standard diamond blades will clog up. Best of luck and please do let me know how you get on.

[@princethewondercat]

Good explanation, true they do not tell you what side of the cutting disk should be facing up , with the metal down or as you say facing up. Question cutting hardened steel like a lock or chain, would you use a 1/16" or a 1/8" cutting wheel , thanks.

[@thestonecraftingworkshop7490]

Hi, if using a cordless tool use the thinner blade as it has less drag, for a mains power tool use the thicker blade to take the extra power. thanks for watching.

I cant see which way the nut goes on with the depressed cutting disc. Raised side up or flat?

[@thestonecraftingworkshop7490]

Raised side down, cheers

[@Vilhyto]

I have an old grinder without locking button. How can I change the disks?

[@thestonecraftingworkshop7490]

there is a spanner slot (or there should be)on the machines spindle, behind the disc. you will need a flat thin spanner to hold the spindle while turning the disc spanner.

[@chandbabukhan3803]

Can i use same Rpm of grinding disc and with same rpm grinder is it safe

[@thestonecraftingworkshop7490]

Not sure I understand the question, the speed quoted on the disc is the maximum rotation speed the blade can be used at, if your grinder runs at a speed quicker than the max blade speed then it is not safe!

[@Mendedit]

I think I remember when there wasn't any washer at all, and my first angle grinder (Wolf) had an on/off switch like a light switch. spindle lock, what's one of those?

[@thestonecraftingworkshop7490]

Careful, you may be owning up to being as old as me! Cheers.

[@Mendedit]

@@thestonecraftingworkshop7490 But I still look 30yrs old!

[@Mendedit]

Joking apart I think the steel 'washer' is there to protect the 7/8" hole from becoming elliptical or larger which would make using the disc dangerous to use. And it IS 7/8 of an inch diameter not 22 or 22.2 or 22.23mm. The USA wouldn't stand for it.

[@raysmith13]

What about best before dates on discs?

[@thestonecraftingworkshop7490]

I have never taken any notice of use by dates on discs and I am not going to start now! The blades are resin bonded and should last decades, the only exception I can think of is if the blade is damaged or has been stored in sunlight, this might degrade the resin. As long as it looks ok I would use any blade. BUT ALWAYS use goggles with an anglegrinder, nag, nag nag😊

[@williamknowles5370]

Have Milwaukee 4 1/2 grinder, not matter how it is tighten, there is a blade wobble, alignments are correct ( after reviewing your video.) Txs for your excellent video by the way ! Any advice? wk

[@thestonecraftingworkshop7490]

Is the back nut the correct one, is it the right way round? it will be slotted to lock into place on the spindle. you can tell if it is seated correctly as when it is in place it cannot turn on the spindle. Check for bumps on both backing plate and lock nut. If this is not the problem I can only imagine it is the bearing breaking down. with machine unplugged pull the blade backwards and forwards and side to side. If it "clonks" or the spindle moves the bearing is shot. another thing, is the blade held very tight between the nuts when tightened? if not you may be trying yo use a thin blade without turning the lock nut around. Lock nuts usually have a flange on one side to use with thicker blades. Hope this helps.

[@LykeArgy]

Yeah I just assumed the writing goes towards the blade under the guard, cause that's how you fit the grinding discs so it was just an assumption that it's the "industry standard" but your points make sense

Much needed video to help clear the confusion on grinder blade fitting. As if to add to the confusion Steve I bought that Parkside 20v Cordless grinder this evening in my local lidl and the cutting disc that came installed was fitted label side down...ie label side towards the tool. I watched an unboxing video by someone else on youtube and it too had the cutting disc fitted label side (and silver ring) towards the tool. One unrelated query...did u find that the sound from the motor seems quite thin/light compared to other grinders? I have the Ferrex (Aldi) cordless one and it has a heavier, more re-assuring sound. Ditto for two other corded models I have.

[@thestonecraftingworkshop7490]

Hi Brian, mine does sound more lightweight than a corded tool, but I guess that because it is. I have not yet managed to buy the ferrex version but I think I am right in saying that is 40v? so a bit more powerful. This Parkside tool is definitely for lighter use only but I do like using it, I will be devastated if it proves to only have a short life! Thank you as always for the input, Cheers!

a quick info on proper orientation of blade guard and which portion of wheel in relation to rotation to cut and grind safely would have been nice.

[@barcadoubletreblesixtuple4020]

What is the size of inner bolt@rod of typical normal size grinder? I want to replace it because it's bent a little after I dropped it. I already had new inner outer flange except for the steel rod. I don't want to spend too much money buying bolt maker metric tap wrench and die set.

[@thestonecraftingworkshop7490]

Sorry, I'm not sure what you are asking here. If you have bent the shaft of the grinder you will either need to get a replacement part or buy a new grinder. As far as I am aware there is no "standard" size.

[@hazlbri]

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.

[@thestonecraftingworkshop7490]

Your machine specs show a bore size of 22.2 mm (see Screwfix website). This is standard and is the same fit as 22.23 mm bore size which is a more accurate conversion from the imperial 7/8 inch bore size. You can use any blade with either 22.2 or 22.23 size quoted. I know you can get spacers but I do not know where from. Unless the blade you have is in some way special I would simply buy a new blade to fit. Best of luck!
