Best 5 Inch Bench Grinder Wheels Of 2024: Completed List

Wheel grit

Also available in this section is a selection of grit sizes and types for your wheel. However, there are three that appear to be universally useful. Color is everything when it comes to grit. Typically, the wheel's color will serve as a quick and easy indicator of the grit and application for which it was designed.

Choose the wheel grit with the grit size and grit hardness in mind.

Size

The type of result you obtain depends heavily on this factor. Grit can be broken down into four categories: coarse, medium, fine, and superfine. Coarser grits remove material more quickly, but leave a rougher surface in its wake. A smoother finish can be achieved by using a finer grit.

Hardness

The grid's hardness scales from the easiest (A) to the most difficult (Z). This metric is analogous to shoe size in that it can have different ratings for the same product from different manufacturers. You should use the one you are most comfortable with.

Aluminum oxide grit

You'll most likely come across aluminum oxide grit, and you may even end yourself working with it yourself. Many different hues are available to suit your needs and preferences. If you need a stone to sharpen steel, a grey or brown stone won't break the bank. All three colors, white, pink, and ruby, are more expensive but can cut through considerably more robust materials.

Silicon carbide grit

Most commonly, the color black or green is used to identify silicon carbide grit. The black variant is exceptionally sharp, and it is typically used on softer metals, plastics, and even stone. The green one, which is intended for harder metals, is even sharper. This grit is typically reserved for the last stages of a project.

Ceramic grit

In addition, ceramic grit is gaining in popularity, but it comes at a price. As one of the most pricey varieties of grit, it won't come cheap. This is because ceramic grit doesn't dull like other options. That's pretty cool, right? However, you should know that some companies cut costs by diluting the ceramic with other chemicals. The ceramic won't be the best option unless you have a large budget or want to utilize it in a very specific way.

Motors

In a bench grinder, the strength of the engine is what makes the wheel turn. When the motor is stronger, the wheel can spin faster and with greater force. However, if a bench grinder can reach 3000 or 3600 rpm, you're usually safe from damage, even if speed typically implies you can get your task done faster. There are times when additional force is needed, but for the most part this is a great range to work with when sharpening.

Tool rest

It's important not to overlook the tool rest while using a bench grinder, since it can make all the difference when sharpening tools. Tool rests that are awkward to use or cause discomfort can lead to inconsistencies in the task. Take some time to learn how to use the one that came with your machine. Or, if you're really having trouble, you can always invest in a separate tool rest. They may make the working environment more pleasant and flexible, and they may be necessary for completion of the task at hand.

Speed Control

In addition to the above-mentioned bench grinders with fixed wheel speeds, a variable speed bench grinder gives you the flexibility to set the wheels' rotation speed according to the job at hand. The ability to regulate the rotational velocity of the grinder wheel helps improve the quality and consistency of the finished product.

Safety Features

In addition to the obvious spark guards and wheel covers, an adjustable eye shield and other forms of protection should be at the top of your list when shopping for a bench grinder. Particularly important is the presence of a wheel guard, which will shield the rider from any flying debris should the wheels become damaged.

As with many power tools, safety glasses are required when operating a bench grinder, and while eye shields are helpful, they are not a substitute for proper eye protection. You can always buy protective eyewear separately if the bench grinder you have your sights set on doesn't come with any.

Other features

For the heaviest grinding jobs, a bench grinder with a robust cast iron base and/or rubber feet is recommended (but not required). Vibration is a common problem with these equipment; if the bench grinder has bolt holes, you should use them to secure the grinder to the work surface; otherwise, the grinder should have grip footing to prevent it from moving around.

Work lights, some of which are adjustable, are another useful feature included on some bench grinders. In addition to keeping you and the machine safe, rear exhaust ports help clear the machine of any debris that may have accumulated at the machine's rear.

What can a bench grinder be used for?

You may use a bench grinder for a wide range of purposes. They are versatile and can be used for a variety of metalworking tasks, including cleaning, buffing, sharpening, and even reshaping. The sort of wheel you're using to grind will determine the answer. A rougher grind will remove more material, but it will also be harder to work with.

Do bench grinders need to be bolted down?

You shouldn't have to secure a bench grinder with bolts unless the maker specifies otherwise. In the absence of any specific assembly instructions, a quick check of the manual should reveal that you're all set.

Should I get a 6-inch or 8-inch bench grinder?

If you're just getting started with bench grinders but want to have enough power to sharpen, clean, and grind a variety of blades and tools, a 6-inch model is a good option to consider. Professionals are recommended to utilize the bigger 8-inch grinders.

Do I need a variable speed bench grinder?

A variable speed grinder is useful for those who work on both vehicles and wood, as the lower speed may be used for sharpening woodworking tools while the higher speed can be used for grinding down bolt ends or cleaning away rust from auto parts.
