Bench Grinder Buying Guide: Which Type of Wheel Do You Need?
If it is your first time to be acquainted with power tools around a construction site or in your home, then you should probably know what a bench grinder is before you can use it properly.
To give you a quick summary of this tool, it is actually used to grind cutting tools and do other rough grinding on metals and pipes.
This tool is usually bolted to the floor for better stability when you start grinding. It consists of two wheels that spin at high speeds and mounted on a pedestal.
Depending on the grinding wheel’s grade, it may be used for cutting and sharpening tools like lathe or drill bits. Moreover, it can also be used to shape metal before fitting or welding.
The wheels can be interchanged between a wire brush or a buffing wheel to a grinding wheel in order to clean or polish work pieces like small bolts and pipes. But you should remember that you should not be using the grinding wheel for grinding softer and less durable metal like aluminum.
Sometimes the soft metal can be lodged in the pores of the wheel and expand the heat when it comes to grinding. If this happens, it can cause the wheel to dislodge and damage the grinding wheel. Always make sure that you take the right precautions before you grind anything.
In order to do a good job while you are grinding metal, you should always know how to maintain it at all times so that you do not make any drastic damages to the wheel.
The wheels of a bench grinder sometimes need some cleaning to do a good job of sharpening. Before you start using this tool, always make sure that you know which type of metal to use, how to clean it and how to test for cracks.
Typically the more recommended wheel that you should buy, are those that have the most grit so that you can sharpen and grind the metal properly.
Always make sure that you have the right wheels so that you can get the right outcome that you want without getting frustrated. Also make sure that you do all of this with caution so that you do not get hurt.
Successful grinding is best achieved by the use of a readily friable wheel and positioned in an opened structure to ensure that your cutting is productive. When it comes to grain selection, it will usually depend on the selection and your choice of wheel, but wheel selection will often be determined based on the availability.
If more than one wheel is at risk of disposal, a 46-grit wheel is a good choice for roughing a tool. You should always keep in mind that the finish is not as effective as that of an 80 grit wheel. 80 grit wheels tend to be a bad choice to make if you will be roughing, cutting slower.
Any wheel that is hotter than a 46 grit wheel, is not a good choice if you find that there is only one wheel available.
