How to change the disc on a DeWalt angle grinder tutorial demo instruction DCG412N Fit blade

Hello and welcome to the video. I'm Jimmy the Mower and today we're going to be fitting a disc to an angle grinder.

So i'm sure a lot of you know if you watch my videos on a regular basis I bought the

Dewalt 18 volt brushless kit with the 5 amp power batteries. In there out the drill driver

and I also had this angle grinder. Now I did a quick demo on the angle grinder and show

how great it was and how quick it worked and how well it cut I was really pleased with it.

I've had quite a few questions and queries asking exactly how to change the disk on an

angle grinder and how they should be located. So we'll quickly run through that today now

on this machine here there's a padlock on that side there and you can click the button

in and that stops it from revving up if you take it off it'll work but we'll lock that

but for safety reasons we'll just take the battery off anyway because I don't want that

turning on when I'm halfway through messing around with a disc. Now this is the locking

plate on the front we can unscrew that.

Normal standard thread lefty loosey righty tighty. We all know how that works just turn

it clockwise and it locks it up. The actual locking wheel itself is flat on one side and

then on the other side there's a slight castellation in there you can probably see and depending

on which discs you're using depends on which way it goes on. Today I'm just putting on the

flat discs the one that we use for cutting through bits of metal it's you need to get

in somewhere cut something off normally rusty nuts and bolts that's what we use it for really.

So when you're selecting your disk the most important thing is the diameter of the internal

hole now that has to fit on top there and it has to fit snugly in the center we can

see that we can fit it on both ways it fits on there nice turn it round and it fits on

there nice and tidy too so it fits on both ways. There's a bit of contention about which

way you put it on some people put it on flat so they can see all the writing when they

pick the machine up some people turn it round so that when they've got the machine in their

hand they can see what the actual disc is from that side the preference is yours really

there's no directional markers on this disc so it doesn't have to spin one way or the

other you can flip it over if you know otherwise let me know in the comments below but i'm

going to put it on this way around so everybody can see what I'm doing. Now there's a small

metal plate in the middle and that's what this locks onto and grips so the theory is

that you put it on that way and this locks on and grips that way however if you flip

it over that small metal plate sits against here where it also locks on and grips so i

don't really think it makes that much difference so for now we'll put it on this way so everyone

can see. So put this on spin it round

making sure it's located properly.

Right that's in there that's done now in the olden days they used to give you a two-pronged

spanner that you popped in there and you turn around and that tightened it up and you had

an allen key and you poke this somewhere in the back until you lock the wheel up and you

could tighten it. Things have moved on you've got a little button on the back that you depress

you move the disc ground to an angle now you'll hear it click in that's what we like to hear

click in so that's locked and then the allen key goes in around the front now so we just

find one of these where it will fit and just pull it round a little bit and that's tightened

up so the disk will move but it won't slip on itself. We'll put the battery in take the

lock off now we can fire it up

as you can see it's running nice and true around there because we've got it located

perfectly and that'll be able to cut some metal or wood disc or whatever you've got

in there it'll happily chomp through it and you know you're not going to get any vibration

or any sudden movements from it so there you go that's how to put a disc on. We'll just

take it off as easy as it goes on we remove the battery we'll put the lock on hold the

button at the back

there we go that's that undone spin that off put the disc to one side and then make sure

you put this back on because you'll never find it otherwise i'm sure we've all done

that i'm sure we've all done that so there you go and then that's it's all back together

pop that in your toolbox and it's ready for next time. Hey I hope that's helped some people

out thanks for watching and thanks for all your support anything nice to say put it in
