You definitely need a sharpening tool if you are interested in keeping your cutting tools in optimal conditions. And one of the best sharpening tools available is the bench grinder; and it is also easy to use and very effective, too. They differ in size, in type of grit used, type of wheel, and also use.
Let us see the types of bench grinders (the main ones) available so that you can better take a pick from the plethora of available tool sharpening machines.
- Automotive Bench Grinder: Yes, it has the word “auto” in its name, but no, it has nothing to do with the auto business. This grinder is actually used for grinding a wide range of cutting tools, and also used to shape metal equipment. It is a very stable grinder and as such does not need much adjustment before it can be used. This type of bench grinder is popular.
- Woodworking Bench Grinder: This one is specifically designed for smoothing the dull cutting edges, but it can also be used for grinding wood. Working on a project where precision is key? This grinder is the perfect pick, as it is a bench grinder that runs at a low speed.
- Portable Grinder: Kind of self-explanatory, but we will expatiate. This is a lightweight bench grinder and it is movable from one place to another. If you are on a site, and you have to frequently adjust your tools, the portable grinder will be very helpful here. The disadvantage of this particular type of grinder is that it is not as strong as the other bigger grinders and you won’t be able to use it when adjusting tough metals like steel.
- Standard Variable Speed Grinder: This is one grinder that is up to the task in the sense that it works well for professionals who would usually work with tough steel and metals and would need a stable and sturdy tool. It is sure to serve you for a long time. It can be used with various grinding wheels and the grinder can be used for basically any job. This bench grinder gives you the precision you need and you can easily adjust the speed. The lower the speed, the higher the precision.
We also have a list of bench grinders based on the grit, we have:
- The silicon carbide grit grinders that are used for finishing, and they come in black and green colors. Green is used to sharpen plasma-sprayed materials and tough metal objects, while black is used for sharpening softer objects like aluminum an also plastic and stones.
- Aluminum oxide grit: The most common grit for grinders with brown and gray which are their most common colors because of their inexpensive but efficient nature.
- Ceramic grit grinders: This is quite recent, and it has a very interesting feature. This is opposite from the ceramic grit. The grit is sharper the more it is used than it is when dull. But one thing, though, they are expensive.
