How to remove a stuck disc from an angle grinder every time.
Вставка
- Опубліковано 2 жов 2024
- Obviously the supplied tool is the normal method to remove a cutting disc. But sometimes the blade can become locked onto the grinder spindle if it kicks or someone uses the spanner to fit the disc.

Your videos have had a profound effect on my 15 year old nephew. Since I introduced him to your channel he’s developed a passion for power tools and finally knows what he wants to do when he leaves school (become a power tool repair tech). For the past 6 months he’s bought numerous old power tools off eBay and spends hours taking them apart and putting them back together. He’s now wondering what qualification(s) he needs to study for and that employers expect or look for. If you could provide him with any advice it would be very much appreciated. Thanks 👍🏻
P.S. He’s also wondering if there’s a way of installing bearings that doesn’t require a hydraulic press. Cheers
Well I have a degree in mechanical engineering, but that js not nessisary. Experience is more valuable than papers.
Tell him to also get into electrical repairs. Electrical engineers can demand some big money, in industry doing electrical repairs is always interesting
@@deandohertygreaser Thanks Dean 👍🏻
Steel pipe of different diameters and different sizes of sockets set, long and short you can use to tap on bearings, a bearing puller set to take them off and sometimes heat to expand them and cold to shrink them.
A decent sized vise can be used to press bearings on smaller motors. There are also several types of relatively cheap mechanical bearing presses, but these are also limited in size and power. A third option is to build a D.I.Y. hydraulic press from a hydraulic car jack and some scrap iron, but you need a welder for this. Finally you can look for a cheap hydraulic press, for this kind of job it doesn't have to be very strong or extremely precise, you can get decent ones for as little as $250 brand new.
You can install bearings without pressing by using heat to expand the bearing seat, and freezing the bearing to shrink it. Or the opposite can be done to install a bearing onto a shaft.
You don’t learn that trick in a textbook! Great work as usual Dean!
35 years in the building game and Deano comes up with this !!!! Mate ………… 👌🏻👍
Here in darkest Africa we clamp the disk in a vice and use a hammer and punch to remove the nut. We also lubricate the threads occasionally.
Tragic. Tell me the drift is a softer metal than the disc?
@@kraptastic333 The vice is harder metal than the disc and the punch is softer or at least only mild steel😀
@@andrewallen9993 I am thankful, good luck to you mechanics
We lock the disc in place often by wedging wood then hit the hole with a punch here in Australia
@@OffGridInvestor Here in South Africa we realise that the direction of rotation of the disk automatically tightens the nut when the tool is switched on through inertia.
Every days a school day 👍
Many thanks Dean I've knackered two pronged spanners trying to get errant disc off. Just got the fcuker off like this, I salute you sir 😁
Absolutely brilliant. Love it.
Basically the same method as using an impact driver on a stuck saw nut (make sure to use the right direction, some have counter clockwise thread)
For people not having an sds drill with hammer only mode at hand for this grinder, clamp the blade or the nut in a vice and rotate the machine, works most of the time.
Yeah, right sided blade saws have the standard right/ tight, left/ loosen. Left sided blades have the "opposite" nut.
Watching a lot of SMA in the rust and repair business, ive seen that as an air chisel. Use anti seize paste on the threads to prevent this in the future.
Tell that to customers
or a ring of bare copper wire to separate steel from steel to stop it amalgamating
Round of applause for that one
You're such a clever Lad!
I am using grinders in field since 12 years. I knew hammer and cold chisel combo but this was new to me.
I owe you a pint! .. NO! .. I owe you a thousand pints!! .. You genius! I'm days trying to get the disc off. Thirty seconds after watching your video it's toast!! .. Thank you. Thank you. Thank you 😊
That's a fantastic tip Thanks for sharing 🍺🍺🍺🍺🍺👍👍👍👍
A real irish Doherty? There's a bunch of you folk out in Canada eh.
Holy crap, what a great tip. I always love these tricks of trade.
*Thank You* Dean. Just bought a budget rotary hammer drill so now I have another use for it. Much appreciated. 👍
OMG, that is feckin brilliant! :)
I've been using the feckin vice and even resorted to cutting them off and this is all i needed to do.
New knowledge every time... Thank you dean!
Nice tip dude.
I've done similar but with a Philips screwdriver and hammer.
Also with Mole grips..
Absolutely genius move, thank you for sharing
Man... that was just f*cking brilliant... a fix within a minute..😎 To bad they don't organize Olypmics Games for tool mechanics. I bet you are one of the favorites to walk away with a medal.
You tell me after losing the skin on my knuckles today I could have used the SDS ? No way!!
And for anyone that doesn’t have an SDS drill use a good old fashioned hammer and punch, simple
Thankyou! I have one in the same situation.
I completely wrecked one of those disc spanners but it was rusty to begin with. Then I put my good one on, hammered it and off it come.
Thanks mate I must try that on the wife’s knickers 😂👍🏻 top tip by the way
Brilliant! I have an Erbauer 9" grinder in the van with his exact problem, tried EVERYTHING and ruined the removal tool. I'll be trying this 1st thing in the morning. Nice one, bud! 👍
....update. Blade was off within seconds! Brilliant tip👌
So simple yet something I’d never have considered 😂😂 brilliant 👏🏻👏🏻👏🏻
Great video dean
Great video!
Thanks!
Thank you so much, Dean. Love your accent, but I got the hang of it. I used to not tighten it so much, but that could be dangerous.
Now I can jack hammer it. Thanks again.
I am going to try that this afternoon with a stuck Grinder myself. Thanks!! great tip.
Thanks for sharing that tip mate I'll do that if I ever have a stuck grinder nut
Now you have to do this every time, because you destroyed the holes for the key. I usually break that lock button too if I try too hard, so I like to put the disc in the vice, then use a pipe wrench around the nut. Works every time, doesn't ruin the holes in the nut OR the lock button.
This dosent distort the hole either. Hammer and cold chill dose more damage.
@@deandohertygreaser I see. My method doesn't work with the normal cut discs because they break apart in the vice. I will try your method
Bu açma yöntemi hiç aklıma gelmedi güzel fikir
Clever. I have sometimes had to heat the nut cherry red to be able to break it free. Never tighten a disc with a tool, only do it hand tight.
Exactly. It's only going to get tighter in use anyway
Since I am the proud owner of a knipex cobra 560 this has not been a problem anymore.
I could have done with knowing this trick about 7 years ago when the nut on our angle grinder was always jamming solid.
Absolutely amazing trick.
Brilliant!!!
Not bad I usually just weld on a nut and break it open with a larger spanner, works like a charm as well
Brilliant worked in a oner after I bent the pin spanner trying. Thanks
Glad it helped
I've had to weld a 1 inch nut on and use an Impact. More than one way to skin a cat. Great video. Hi from Australia.
Its actually a good grinder, its brushless.....
No it's not, it's a corded brushed grinder. One of makitas worst.
@@deandohertygreaser No brushes fitted, it was a close shave at humour....
I wish i had of learnt this 20 years ago it would have saved a lot of bloody Knuckles!!
This has happened to me a few time thanks for the tip ❤️
No problem!!
Legend thank you!😀
No problem 👍
Off to grind down a bit and regain the use of my big grinder that has been stuck on a shelf for over a year! Cheers for that.
I have been trying to unstuck the disk for litteraly 3 hours with all kinds of methods .
I used your method by inserting a metal rod then used hammer mode , it was a life saver .
Thank you, it resolved my headache and it did work perfectly and I have exactly two the same tools.
Although a little bit of holy WD 40 around the locking nut , would have helped as well .
I'd successfully used that same technique for removing a pin that was stuck in a hinge.
I think whoever was using that 9", shouldn't be using a 9". Great tip though 👍
They dont stick when used properly. You should always be able to take it off with your hands.
That's barbaric! One tap with a hammer & punch and it's loose.
Thanks fixed my problem
You're a genius!
A large pipe wrench or "Stillsons" wrench is far easier : )
I learned a trick in the Navy,
If something won’t loosen, try tightening, then loosen
That is very true. You will often see me tightening things up before loosening them.
Thanks for showing me how to use grinder to get nuts hammered
Or you take second angle grinding and cut the stucked blade on first one
Genius
Why doesn't the grinder have the brushes in?
I hardly believe that he can fix everything.. He's good tho 👍😎
Why not spray the joint with Plus Gas?
An hammer and chisel works as well and cost less.
lol. brilliant
Wait until he discoveres the sds click!
How to lose the spanner and use a $300 tool instead
You can also use a hammer and a cold chisel
Good work
Almost thought You have same model of SDS drill as me, but mine is the DHR243 with the quick-change chuck. You get SDS chuck and the normal drill 13mm one. Those drill look identical apart from the 243 having longer chuck.
Have you seen the trick where you press the trigger and let it go so the blade is spinning then you press the button that stops the blade and it usually knocks it loose
it also eventually smashes the gearbox and destroys the lock pin. Iv had to fix 100s of grinders for people who have done that,
When all else fails, here's how to remove a stuck disk from your grinder.
Buy an SDS lol
Just teasing... 😊
Nice!
If you wanted to do the complete opposite, you could always loctite the threads before overtightening the disc.
Don’t you just push the lock button in and slam the whole grinder by the disc downward on the edge of a table?
At least that’s how I’ve done it in frustration before lol, and it worked.
I like this method better though.
Spin up the grinder, let it lose speed to it’s almost stopped smash the lock button down and let inertia take care of the rest
No, don't do that. It will smash the alu housing holding the pin. It's a common repair I see all the time
I’ve always done this. It works great: that masonry wheel was bent as fuck lol
super napad
Never saw a floppy diamond disk before
Simple . A mandrel , and a hammer .
Great tip…one I will remember! 👏👏👏
"A toy" ? It's a perfectly good machine for many people that may not need to use it daily and under heavy loads .
It's a 7inch grinder body makita tried to make into a 9inch grinder. It's useless
For YOU!
100% works
That was a genius move.
Great tip 👍👍
Great use for those burnt out bits!
Un chasse goupille et un marteau
Ca suffit pour Débloquer
Les anciennes meuleuses n'avaient pas de bloquages et lorsque les trous étaient usés il fallait se débrouiller 😂😂😂😂😂
Non car tu n'as pas trois bras mais deux.
@@fancraft1266
pour le droitier
La main gauche sur le disque en tenant le chasse goupille,le marteau dans la main droite et le tour est joué
Vous critiquez une façon de faire que vous ne connaissez pas
Moi je l'ai fait mainte et mainte fois et je l'avais appris avec des collègues
Il n'y avait pas tout l'electro portatif de maintenant
Why not use impact wrench? 🛠️
On what.
@@deandohertygreaseron your burat 🥳🥳
Experience shows
Top tip!!
Champion
19Amp monster grinder, Dean says its a toy.
When most people use a 12" a niner is gonna seem small 😊
❤🇦🇺
Or just use a hammer and a screwdriver or sumtin...
Nice 👍
Thanks ✌
Legend 👌🏻🍺🏴
After you see it it's kind of obvious...
