A Little Background

Bench grinders are heaven sent innovations that help us sharpen tools easier than during the old ages. Back then, we had to manually sharpen tools using rods and such and this can lead to injuries when not done properly. Today, our lives are ruled mostly by machines to speed up work and enhance safety – bench grinders do just that.

Because bench grinders work at exceedingly fast speeds, one must learn how to use it properly. The improper use of a bench grinder can still pose a threat to your safety and can lead to injury to either the tool or to yourself. Bench grinders can speed up jobs, no doubt about it. But you also have to learn a little bit on how the machine works before you put your knives and cutters in.

The wrong usage of a bench grinder can lead to imperfectly sharpened tools and overheating. This is because if you don’t move the metal tool quickly, the grinding wheel can cause it to overheat and it can be bad for your cutting tool or sharp tool in general. Sharpening tools take skill and patience so you have to know the basics first before using a bench grinder.

Do know that bench grinders can have different wheels which work for different kinds of metals and tools in general. These wheels have different grits which can be for coarse or medium fine or even the finest sharpening power. From garden tools to kitchen knives, you can conveniently choose your grinding wheel as to the kind of tool you want to sharpen.

Of course, you cannot use a bench grinder without proper safety gear over your eyes, hands and face. Much like welding and using other heavy duty power tools, bench grinders require you to have safety gear even if the bench grinder itself has protective shields.

How We Picked

In picking the best bench grinder, you should consider the speed of the wheels. In fact, a bench grinder with a variable speed is a big plus point. But be careful – faster speeds mean you get a closer feel for overheating, whereas slower speed bench grinders work slowly but finely and quietly if you are not really chasing time, and are ideal for home use.

Know if the bench grinder has safety features such as shields. Of course, aside from covering your eyes with goggles and your hands with gloves, you should have a bench grinder with protective shields such as a spark shield to keep the sharpening at bay.

Is the bench grinder relatively lightweight but pose heavy duty sharpening or buffing power? If you look forward to taking the bench grinder from place to place then it should be easy to carry but not too flimsy that it might break apart. Rubber feet to keep it from slipping are also a plus point.

You should know as to what kinds of tools can be sharpened by the bench grinder. For instance, some bench grinders are only applicable for smaller tools due to their size and some are bigger and can accommodate a variety of tools – from gardening to kitchen tools.
The size of the wheel and its grit are decisive factors in choosing the best bench grinder. Some wheels come in 6 inches and some come in 8 inches – it roughly depends on your budget and your sharpening needs, as not all tools are the same in size, usage and quality.

Other Frequently Asked Questions

Q: What is a bench grinder and what is it primarily used for?
A: According to the information laid down by Wikipedia , a bench grinder uses abrasive wheels to do grinding, sharpening and polishing jobs. It is mainly a tool for shaping and sharpening lathe tools, drill bits, knives and the like. Today, bench grinders are usually mounted on a work bench or a special bench grinder stand and the wheels of a bench grinder are designed only for steel. This is because aluminum and similar softer metals can get into the pores of the wheel and dislodge or compromise the sharpening quality of the grinding wheel.

Q: Can you give us some tips on using a bench grinder?
A: According to the guide by Popular Mechanics , you must know all the parts of the bench grinder and how each part works and different wheels can pose different grinding purposes.

Some wheels are meant for buffing while some are meant for sharpening. Also, other wheels are meant for polishing or fine cleaning your metal object. Usually, bench grinders have two wheels – a 36-grit coarse wheel and a 60-grit wheel. The coarse wheel is ideal for gardening tools and lower sharp tools while the 60-grit wheel is usually for chisels, knives, plane irons and others. The wheels with above 100-grit are applicable for fine sharpening such as kitchen knives, metalwork and others.

In general, you have to keep the metal object moving as you sharpen it to prevent the metal from overheating. As much as possible, you shouldn’t apply too much speed on delicate and small metal tools since they can overheat faster. You should get a bench grinder that has a cooling bench or if not, just splash it with cooling water afterwards.
