How to Buy a New Bench Grinder


Given that manufacturers have placed a wide variety of bench grinders on the market, it is best if you keep some basic information in mind when you go shopping for such an item. Also, try and leaf through some of the best bench grinders reviews to see what other buyers have to say about the different models on the market.

Grinding wheel

A bench grinder has one or multiple grinding wheels that operate the actual grinding process. These wheels are abrasive and, depending on the type, can work for a broad range of tasks. Therefore, you should think about the use you are going to give to the grinder. Grinding wheels are distinguished based on two major characteristics: the grain and the grit. The grain refers to the type of abrasive, or material of the wheel. From the common aluminum oxide and zirconia alumina to the latest, strong, ceramic aluminum, there are plenty of materials and alloy combinations you can choose, each one working best for a particular type of work.

The grit, on the other hand, reflects the size of the abrasive grains of the wheel and can go from the coarse type used for less refined grinding to the ultra fine type that works for finishing and brittle materials. Also, be sure to look for a proper size of the wheel, as it can vary from 3 inches to 6-8 inches, or even more. For the everyday household jobs, an 8-inches wheel should be more than enough.


Motor power

The power of the motor can affect the machine performance in two ways. First of all, a large, powerful engine will do the job faster and will work on tougher materials and workpieces. Secondly, with great power comes great heat, which ultimately might make you stop in the middle of the action to let the machine cool down. Also, you should remember that a large motor will also be a large electricity consumer.


Safety accessories

The grinding process consists in chipping away small or even large bits of the workpiece. Because of the turning speed of the wheel, these parts will fly off the tool in different directions, making it very easy for you to get hurt. Also, while it’s turning, the wheel itself will become hotter and hotter, causing burns if handled carelessly. To avoid such risks, look for a bench grinder that has an eye protection panels, a cooling tray or an easy to reach and prominent off-button.
