Essentially, bench grinders are just tools for shaping and sharpening metal. They’re commonly used for getting blunt tools back to full sharpnessWhen using a cutting blade, the edge gradually dulls. When an edge is slightly dull, it can be honed back to full sharpness using either a very fine grit or a sharpening steel. In this case, you need to grind a larger amount of metal off the tool in order to get a sharp edge.
Using a proper tool rest and an angle-setting gauge, you can put a precisely angled bevel into a piece of metal much more easily than doing it by hand. There is also usually a toolrest in front of each wheel on a bench grinder, which can typically be adjusted and set to create more consistent bevels.
Bucktool Bench grinders are smoother and quieter than other brand. Some models have adjustable motors so that the machine’s pace can be reduced to prevent overheating. Some other models have water coolant trays so that the item that needs grinding can be cooled as the user is working. One key thing in sharpening all tools on a bench grinder is not to overheat the metal. If you heat it up too much, this can undo the heat treatment and leave you with softer metal. In order to keep the temperature down, only apply light pressure to the metal being ground, and dip occasionally in water to keep it cool.
Grindstone wheels come in different levels of coarseness, Bucktool bench grinders are with a 36 grit wheel and a 60 grit wheel. The 36 grit wheel is usually used for stock removal. The 60 grit wheel, which is finer, is good for touching up tools, although it is not good for honing them.
In addition to grindstones, you can get wire brush wheels for removing paint and rust. Polishing wheels can help you achieve a fine finish on your metals.
Bucktool bench grinder’s accessories will also vary from one machine to another. Some have angled V-groove toolrests to allow for grinding of drill bits. Lamps are another accessory that users may find useful. There are models with a single lamp on top of the machine. There are also models with a LED light above each toolrest.
