The last part of getting into different types of wheels is the tool rest. This is used to place the tool you are working on to when not using it. This comes in handy if you are needing to sit the tool down to adjust the speed of the grinder or if you need to change out a wheel.
The tool rest is also used to rest the tool on while working on it. This keeps you from having slips and provides more balance. While still a part of the bench grinder I am breaking it into its own section because there is a lot to be said about them. The wheel is the part that is doing all the real work and there are many different types. You have course wheels, fine wheels, straight wheels, tapered wheels, and even more.
Each wheel serves its own purpose and has a use that it does best. On top of the different types, they are also made with different material on the grinding surface and can have different grit. Different wheels can even have different hardness and also have an rpm rating.
When choosing a bench grinder wheel it is important to pick one that is designed for the job you are doing. You also want to make sure it is rated for the speed of your grinder. If you use a wheel on a faster setting than it can handle, then you could end up with the wheel exploding. This can still happen with proper use and that is another reason for the wheel guard, but it is much less likely to happen if you take care of your wheels and use the proper ones. The most commonly used wheel is the straight wheel.
It produces a concave surface which makes it good for sharpening chisels and other tools. Any type of surface grinding can be done with a straight wheel, but they can also do the centerless and cylindrical grinding.
Another type of wheel is a tapered wheel. This wheel is tapered towards the edges and can be used for more delicate work. One common use for this type of wheel is grinding threads or gear teeth. Due to being tapered you can get into the groves a lot more easily using this wheel. If you got a lot of saw blades that need sharpened then you will want to invest in a saucer wheel. A few other wheels that exist, but are very specialized are dish cup wheels and straight cup wheels.
If you have a used for one of these, then you will probably know what it does. If you need a larger grinding surface than the standard horizontal wheels can provide, then you can get a cylinder wheel. They are hollow and have use vertically or sometimes horizontally if your grinder is big enough.
They can go all the way up to 12 inches so if you ever needed to grind a big sheet of metal all at once, then this might be the option you will have to use.
If you are working with the really hard material, then you may want to consider getting a diamond wheel. These are coated with small bits of diamond on the edge and can cut pretty much anything. Speaking of diamond wheels leads perfectly into grit type. The diamond wheels have a diamond grit. The most common type of grits, however, are normally aluminum oxide which can be a variety of colors from pink, white, to red, or brown. Next is silicon carbide which is black or green.
Another grit is ceramic which is blue or pink, or you can have a combination of these. The most common grit is the aluminum oxide and the most common colors are gray and brown. Color effects toughness as well as cost. The gray and brown are the workhorses thanks to the fact that they are inexpensive, but get the job done. They are general purpose and can be used on low or high carbon steel. Pink and white are used on harder steel which needs a cooler cutting action to avoid burns and they cost a little more than the gray and brown.
Ruby red is the most expensive and is used on tool steel and is an especially tough grit. Silicon carbide is normally black or green.
The black is used on softer metals such as aluminum and even on plastic. The black silicon carbide is extremely sharp.
