SOURCE: angle grinder

on a grinder the nut that holds the wheel on has left handed threads.....that means it has to be turned in the opposite direction than conventional nuts do..there should be a button on the casing to hold in..this keeps the grinding wheel from turning wheel being removed....remember to unplug first..thanks and have a great day

SOURCE: I don't know how to change the grinding blade on

There is a nut that you release from the middle of the grinder wheel, (grinder blade)
This nut is flat and has four holes in it.

You will see you are providing a spanner wrench to remove this nut. The wrenches' actual name is Lock Nut Wrench. It has a U shaped end with two pins sticking out. On on each side of the U shape.

The pins are inserted into the holes in the flat lock nut, located in the middle of the grinding wheel. The wrench is laid flat against the grinding wheel, with the two pins of the wrench going into any two holes of the nut.

At the top of the Makita grinder you will see a Black button. The button is pushed down to keep the grinding wheel from spinning. Holds the grinding wheel in place, as you turn the lock nut loose. When you release the button, a spring inside pushes the button back up out of the way.

As you view the Makita grinder, Release Button towards the Back, grinding wheel towards you, the nut is turned to the LEFT, to loosen. It is a Left threaded nut.

The grinding wheel spins to the Right. Using a left threaded nut insures that the nut will stay tight, due to the direction the grinding wheel spins.

How to Change a angle grinder disc


My angle grinder came with a special wrench to take off the disk. I have a small button to push that locks the shaft. I push it gently with it UNPLUGGED while turn the grinding wheel by hand till it locks. Then I use the wrench to undo the "nut" that holds the grinding wheel on.

Should the wheel move in stopoped position


It should rotate freely, but it should feel like it's turning gears on the inside of the grinder. It should NOT be floppy, and it should NOT spin as if it's not turning gears inside the grinder. It should run straight and true.

It's possible that you didn't remember to install the inner (backup) arbor washer before installing the wheel. If you do that, the wheel will spin completely freely on the arbor shaft. Find that washer and install it under the wheel.

It's also possible that you installed a very thin cutoff wheel but your grinder won't accept one, that it requires a full-thickness grinding wheel. Some grinders won't grip a very thin cutoff wheel correctly.

If you are using these disks you need to apply very light pressure with the angle grinder and ensure you aren't putting any side pressure on the side of the disc.
Also imagine a line at a tangent to the disk. This should be kept at a shallow angle to the work piece to prevent the edge of the metal digging into the cutting disk.
As a rule of thumb you have the correct angle when the sparks are flying at less than 30 degrees back towards you.
Also make sure the retaining flange nut on the angle grinder is the correct way around to grip the disk, sometimes the nut has to be reversed to grip grinding discs.

To sharpen tools


The angle things on the grinder are usually set up for drill bits and never moved again. If you need to sharpen your shovel, I would get a 4 1/2 grinder with 80 grit disc in there and grind away from the edge, Not into it, it cuts 10 times faster, cleaner, straighter, than the grinder, use fit or the lawn mower blades too, and the machete, use the grinder for your drill bits and other precision type stuff, don't let the wheels get rounded off or uneven, use a wheel dresser if they do. I have a couple grinders set up in my shop, one wheel for finer stuff, then a wire wheel, then a green wheel for carbide, and then another wire wheel. I use a 1 inch belt for knives and finer stuff, and a 10 disc for serious stuff along with the 48 inch belt. So you can see, I use them a lot. But if you need to use the grinder for your shovel, I would not use the angle stops, I would do it freehand and you can only cut the outside edge, and it will be hard to get it around there. You might have to take the angle stops off. Hope this helps.

I cannot get off the abrasive cutoff wheel I put on the grinder


I believe the thread is left hand, but close inspection should verify. Also you should never over tighten cutoff wheels or grinding wheels. You should be able to remove with a gloved hand while holding button on top with the other hand
