A bench grinder is a great choice for anyone who is doing DIY in and around the home. But did you know that there are a couple of other types of grinders that may also fit your needs?
Die Grinder – A hand-held rotary power tool, a die grinder can help you grind as well as sand and polish metal. In fact, you can do the same with wood and plastic.
Angle Grinder – Another hand-held power tool, the angle grinder can be used for grinding and polishing.
A die grinder is smaller than an angle grinder and is great for more intricate and detailed work. It’s also very portable. The angle grinder is a compromise between the die grinder and the bench grinder in the sense that it’s portable and also big enough to grind fairly large surfaces. While the die and angle grinders offer portability, they lack the power and versatility of the bench grinder. As such, the bench grinder is the best option for those with a good space at home for DIY such as a workshop.
Bench grinder uses
The purpose of a bench grinder may seem pretty self-explanatory. However, there are several different uses for the bench grinder that many people don’t realize. It’s a very versatile piece of equipment that can help you in several ways. With it, you can not only shape and sharpen metal but you can also cut and clean it too!
Carpentry – Whether you’re building furniture or renovating your entire living room, a bench grinder can help smooth those rough areas as well as level joints.
Flooring – You can make flooring so much easier with a bench grinder. From removing grout to raising nail heads, a bench grinder can make DIY flooring quicker and easier.
Painting – If you’re preparing to paint but need to level any swell or even get rid of some old paint, a bench grinder can help. It acts like sandpaper except it’s a lot more efficient!
Plumbing – Bench grinders are great for plumbing. This is because you can do everything from cut worn-out pipes to help smooth them out.
6-inch or 8-inch – Bench grinders come in a range of sizes. However, the two main types of bench grinders are the 6-inch and the 8-inch. This refers to the size of the actual grinding wheels. The 6-inch is fine for anyone at home since it has enough power to carry out the most DIY tasks. The 8-inch wheel is more for industrial applications often done by professionals.
Types of wheels
It’s one thing to choose a bench grinder and it’s another to choose the right type of wheel! Making the right decision can make your work quicker and easier. There are several things to think about when it comes to grinding wheels. First of all, you need to think about the material that needs grinding because this determines the type of wheel you should use. For example, an aluminum oxide wheel should be used for grinding steels while a silicon carbide abrasive should be selected for cast iron. Materials that are particularly hard and brittle require a softer grade of the wheel with a finer grit size while softer materials work best with harder grade wheels with coarse grit. Here are a few of the wheel types you can come across:
Straight wheel – This is the most common type of wheel and it’s good for applications such as sharpening chisels. Straight wheels come in various sizes and they’re best for surface grinding.
Cylinder wheel – A hollow wheel, the cylinder wheel can only be used with horizontal or vertical bench grinders. These wheels tend to be quite large (they can be up to 12 inches wide) and help produce flat surfaces.
Tapered wheel – For grinding threads or gear teeth, a tapered wheel is appropriate. Because this wheel tapers off towards the edge it is ideal for more delicate work.
Other types of grinding wheels include saucer wheels, diamond wheels, and cut-off wheels but these are specialty wheels that are very rarely needed when working in and around the home.
The 5 Steps to Buying
Buying a bench grinder can be made easier by following 5 steps: identifying your needs, deciding your budget, selecting a brand, comparing the market and finally; buying!
Identify your needs – It may sound obvious but identifying what you need a bench grinder for is the single most important thing to consider before purchase. If you buy any bench grinder you find you may find out that it’s just not suitable for you. For example, if you’re looking to sharpen then you want a machine with a lower RPM. On the other hand, you’ll want a bench grinder with a higher RPM for buffering. Should you need a bench grinder for both, you should look for one that offers variable speeds. However, this may cost more.
Decide your budget – If you have a specific budget in mind, it can make the decision-making process a little bit easier. This can help you narrow down the brands you’re looking at, as well as help you decide which features are essential and which aren’t. Are you willing to sacrifice on power? Can you do without variable speeds? These are questions you need to ask yourself as you decide on price. There are some good quality bench grinders available from lesser-known brands that may well offer you better value if you are on a budget.
Select a reputable brand – As you would expect, the better the brand, the more money you will end up paying. This usually equates to better quality but that’s not always the case. As mentioned before, there are some lesser-known brands with some very competitive products. However, the biggest brands are usually popular for a reason. It’s not just the quality of the machine that’s important. It’s also about customer service if you have any questions or if you’re not entirely satisfied with your purchase. DeWalt and Craftsman are a couple of examples of big brands.
Compare the market – You’ve certainly made a great start in deciding which bench grinder is best for you and your needs. By checking out our detailed reviews and exploring our extensive collection of tips, the process should be quicker and easier. However, there are just so many great bench grinders out there. While we highly recommend the bench grinders listed in our guide, we also encourage you to take a look at the many reviews online before coming to a decision. Be sure to check various online stores to compare prices and get the best deal possible.
Time to purchase! – You’ve finally decided on the bench grinder for you – that’s great! As you’re buying you should check what sort of warranty the product comes with (just in case!). It’s also important to check if the grinder is being sold with any accessories as this can be an extra incentive to buy one bench grinder over another. However, accessories such as wheels can be bought very easily online so this is not essential. Finally, be sure to read all of the instructions well as there are several safety issues to keep in mind with such equipment.
Though we have found the best bench grinders on the market and reviewed them, it is still important that you have a basic understanding of the factors that are critical to the performance of the machine. Here are some of the most important features you must consider before settling for a particular bench grinder:
What you need it for
Just like with every other tool, bench grinders are not made equal. Some are perfect for industrial application and others can only handle small and medium projects. It is important that you buy a model that will be suitable for the work you need it for. You should also consider how often you will be using the machine.
Brand
If you look at the array of products we have reviewed, you will notice that they are all from reputable companies. This may not seem like the most important factor, but it is still essential that you buy bench makers made by reputable companies.
Size and power
We are discussing these two factors because they are related in most models. Generally, bigger models offer more power except in rare cases. Most small models deliver just enough power to handle most non-industrial grinding jobs. Depending on the kind of tasks you are going to perform with the bench grinder, buy a model that offers enough power to get the job done efficiently.
Speeds
Speed is another important factor to consider before choosing a bench grinder. Though high-speed grinders in the range of 3500 RPM are admired for their abilities to get the work done quickly and effectively, some tasks are best performed with low-speed grinders in the range of 1,700 RPM. Depending on the type of job you will use the machine for, choose the one that offers the right speed.
Wheel of the Grinder
It is also important that you consider the wheels of the grinder. It is important that you get bench grinders that have wheels with different grits. Almost every modern model comes with one medium wheel and one coarse wheel.
Other Important Features
There are some other important features that you need to look at before choosing a bench grinder. Tool rests, for instance, are critical to the quality of the job you will be able to achieve with the grinder. Eye guards are also important for the safety of the users. You also need to look at the lighting technique used by the machine; while inbuilt lights are great, flexible lights can also perform satisfactorily and let you work in poorly lit conditions.
Frequently Asked Questions about Bench Grinders
Is faster always better?
Generally, speed is important in getting the job done quickly and efficiently. This, however, does not mean that speed is better at all times. Some jobs require lower speed grinders. Delicate tools, for instance, need to be sharpened at low speed to prevent overheating.
Are there safety issues I may experience using bench grinders?
While using the bench grinder, flying debris and sparks are almost inevitable. They are the major safety issues you need to be aware of. Most manufacturers include safety eye guards in their package and it is important that you use them or goggles anytime you are using the grinder.
How do I care for my bench grinder?
Generally, bench grinders do not require so much in terms of maintenance. If you use them under the right condition, they will be able to stand the test of time. Wheel dressing, however, is an important requirement that you need to respect. This will square the wheels and round them, reducing wobble and exposing fresh grit to keep the machine working smoothly.
What is the best grinder for a beginner?
Grinders that have tool rests allow for precise positioning of the work to get the job done properly. These are important and will help anyone that doesn’t have serious knowledge of using bench grinders. It is even better when the tool rests are adjustable.
Conclusion
If you are buying the bench grinders for the first time, there are a few parameters you have to keep in mind. Firstly, the power of the motor of the bench grinder matters a lot as it can make the job easy and quick. The size and the distance between the wheels are important, depending on the size of the objects you will be working on. The larger the objects, the larger should be the wheels. Besides, there must be lights for better visibility and achieving accuracy in work. You can do precise work with focused light. Apart from that, the stability of the base, the noise, and the protective guards are other points that we have considered while choosing the above best bench grinders.
