Best Bench Grinder – Buyer’s Guide
Any time that you purchase a power tool, safety is going to be the number one priority that you consider when making a purchase. These tools should all have some safety precautions in place that are designed to make sure that you do not get injured when you are using it.
There should always be adequate safety guards in place over the grind wheels to make sure that sparks do not fly out and injure you. In addition, you should always wear goggles to protect your eyes. Also, the grinding wheel should have a guard in place covering the wheel so that loose clothing has less of a chance of getting caught in the machine.
What are other important features to consider when purchasing a bench grinder?
Quality of the Materials
When you purchase any power tool, you want to get a unit that is designed to last for a long time. The bench grinder will also make it much easier to get a professional level of sharpness on your tools. A manufacturer that stands behind their bench grinder will give you a nice warranty on the purchase of the product, but you can extend the life even more by performing the maintenance that is suggested in the manual for the upkeep of the machine.
The Power of the Motor
In most situations, the size of the motor directly reflects the amount of power that you will get from the machine, which is why the motor that you choose will depend greatly on your needs. If you are consistently working with hard metals, then you may want a larger motor to make sure that it can do the job fully without overheating. If you are a DIYer who does simple projects at home, then you will probably be able to use a smaller motor instead.
The Type of Wheel
There are a number of different types of wheels that you can get for a bench grinder, the ones that you select will depend on the projects that you will need to take on in the future. Some are designed to cut while others simply polish. Here are some of the different types that you can choose from:
- A rough stone is great for repairing and reshaping many of the tools that are in your toolbox.
- A smooth stone is great for flattening tools and removing inconsistencies in the metal.
- A buffering stone is ideal for removing rust and making metal shine.
- A white sand quartz stone is typically used on brass and copper materials.
- An aluminum oxide stone is perfect for shaping steel.
Type of Cooling System
When you are cutting and shaping metal, it tends to get hot, which is why it is important to have an adequate cooling system on your bench grinder. Some bench grinders have a cooling system that is built into the machine that allows you to sharpen and polish metal without needing to cool it off in any way. Others overheat quickly, so you may need some metal shavings or cool water to cool it the tools off occasionally.
Wet grinding is an option that keeps your tools wet as you grind them. This wetness helps keep the friction between the tool and the wheel down, so it does not overheat. Since the tool stays cool, you will be able to sharpen your tools much more quickly and efficiently.
Ability to Sharpen
After a lot of use, your grinding wheel is going to lose some of its ability to sharpen tools. The bench grinders come with a diamond cutter that is designed to sharpen the wheel and make it shape your tools like it is brand new again. When you are able to sharpen the wheel yourself, you will not have to replace it quite as often, which will help you save money over time as well.
Ability to Illuminate
If your power tools are located in the dark corners of your basement or tool shed. Then you may want to consider a bench grinder that is able to provide its own light. Improving your visibility while you are working is a great way to ensure that an accident does not occur because you were working in a less than ideal lighting situation.
Final Thoughts
As you can see, there are a lot of great bench grinders available for you to consider. They all offer the same base functionality, but some have more complex cooling systems, motors, and grinding wheels that could be useful. You need to select a machine that will last for years so that you can get the best value from your purchase. Who knows, maybe someday your tools will be able to maintain their sharpness, but for now, the best way to shape and sharpen a tool is with a bench grinder. Which one will you choose?
