Features to Consider

If you’re going to look at a bench grinder you want to make sure it has all of the features that you need in order to accomplish any task you’re going to put before it. You don’t want to spend a whole lot of time and money on something only to find out you’re going to need to replace it rather than be able to do what you need to. We’ve found a series of great features that you’ll want to at least take a look at before you make a choice about the bench grinder that you want for your workshop. Each one is up to you, but it could make your job easier.

Worklight

One of the first things that you want to consider is whether the grinder that you’re looking at actually comes with a worklight. You’ll also want to look at what type of worklight it actually has because this can be an important aspect as well. For example, some worklights are flexible and attached directly over the center of the unit. Others may be built directly into it and they may even be located over the wheels instead. Some units actually have more than one light attached, which helps to make it easier for you to see what you’re doing in different areas of the grinder.

Wheels

You want a system that is going to offer you a number of different wheel options at least, even if it doesn’t come with all of them. Most systems are going to offer you a coarse and a fine or medium wheel right with the kit, but not all of them will. Make sure you know what you’re getting and also that you know what type of wheels are going to fit so you can purchase after-market add-ons and accessories as well.

You don’t want something that only has a small number of wheels available. You also want to look at what type of material the wheels are actually made of. Vitrified aluminum oxide is a material that’s primarily used for grinding steel. On the other hand, silicon carbide is better for things like cast iron and nonferrous materials.

There is also a range of other stones that you could choose from. It’s going to depend on your personal preference as well as the type of material that you’ll be working with most frequently. It’s also going to depend on your price point because different types of stone and other materials are going to cost you a little more than others.

Size

There are plenty of different sizes when it comes to bench grinders. We’ve looked at miniature options that are only 3” and larger ones that are 8”, as well as several in between. You’ll want to look at the type of projects that you’re primarily going to be doing and then make a decision about which size wheels are actually going to help you the most. Whether you want something large or small is primarily going to be based on that and your own personal preference as well.

Speed

Finally, you want to take a look at the overall speed of the unit. You need something that is going to give you enough speed to really get the job done. The faster it spins the more it’s going to do and the faster it’s going to do it, which is definitely a benefit for you. With most systems getting between 3,000 and 3,600 revolutions per minute you want to get something that can at least go that far.

On the other hand, there are plenty of options that will go higher than that if you want even more power. The key is not getting something too strong for your intended purpose, but strong enough to do what you need. There are also variable speed options that can allow you to change between high and low power.

Wrap Up

If you’re looking for the best option when it comes to bench grinders you’ll want to take a look at all of the options, but you’re definitely going to want to look at the WEN 4276 Bench Grinder, which offers a 6” wheel. You’ll be able to accomplish a range of different projects and it provides 2.1 amps of power, which means you’ll be able to get more intense projects completed as well as minor ones.

Compared to the other options it has a slightly lower level of power, but it still has several great features that balance this out. For anyone that’s looking for more power, there are other options, such as the Delta Power Tools Grinder or you might be looking for something a little smaller like the TruePower 199.

These options are each going to give you benefits but if you want something that’s all around we still stick with the WEN 4276. If you’re interested in getting one for yourself you can check it out right here and buy it for yourself or check above for links to purchase any of the other options we’ve found.
