Taking a Look at the Best Bench Grinders to Buy Today 

What is a Bench Grinder?

The bench grinder is a staple of machine shops worldwide. You would be hard-pressed to walk into a shop, whether it was a mechanic’s garage or a hydraulic warehouse, without spotting a bench grinder bolted to the wall. And while bench grinders are imperative to smoothing rough metal, sharpening your chisel, or getting an extra edge on your old, worn-out screwdriver, there are uncountable ways to use these great devices. You can definitely benefit from installing a lightweight, heavy-duty bench grinder in your home or outside workspace.

Bench grinders generally come in the same ready-to-use size, equipped with two separate wheels to allow for rapid grinding and buffing of different materials without having to switch the wheels. The two main sizes of bench grinders are six-inch and eight-inch. Outside of typical machine shops where bench grinders are used to shape metal, sharpen tools, and get the muck and rust off old pieces of equipment, many other jobs can benefit from using a quality bench grinder.

If you are practicing carpentry, reworking your flooring, embarking on a big painting project, or doing some home plumbing, a bench grinder is going to help you out a lot. You can use this tool to smooth rough and worn wood, to level joints, to remove grout and raise nail heads, to cut aging pipes, and more. This is an all-around great device with a ton of versatility. Think about your bench grinder as a stationary sandpaper wheel, only stronger and able to buffer, scrape, sharpen, cut, and sand just about anything in a matter of seconds.

Since you’re thinking about buying a new bench grinder for your home workshop or industrial enterprise, you really can’t go wrong with any of the great choices on our list. Keep in mind that these are bench grinders designed to mount directly onto a workbench or onto a wall. If you need a handheld grinder for a portable job, you are going to need a suitable die grinder or angle grinder. These come cordless or corded for grinding in tight spots. Many can be hooked up to an air supply.

Bench Grinder Buyer’s Guide

Let’s get down to business. You want to buy a bench grinder and you want to buy the best there is. That being said, you don’t want to spend a fortune. The ideal solution is to find an affordable bench grinder that is going to facilitate all your needs without it needing to be replaced in the near future. To do this, start by identifying the specific needs for your business. Not all bench grinders are created equally.

Motors

You don’t want something that is overkill. If you’re just sharpening knives or tools, you don’t need a massive motor that’s outputting big RPMs. Big RPMs are more for heavy-duty buffering and serious industrial applications. Then again, a bench grinder with adjustable speeds is going to give you ultimate versatility because you can switch speeds between jobs. Just keep in mind that being able to adjust the speed on your grinder is going to cost a few more dollars, especially for a high-end piece of equipment.

Grinder Wheels

More important than the motor of your new bench grinder are its wheels. The two main sizes of bench grinder wheels are 6 inch and 8 inch. This refers to the actual size of the grinding wheels that are fixed to each side of the housing unit. Think of the wheels like an old craftsman’s sharpening wheel from centuries ago, only smaller, faster, and mechanized, and equipped with two wheels rather than one.

The six-inch wheel is the most common, especially for home workshops or for installing inside of professional warehouses where it will receive light use. The 6-inch wheels have all the power and toughness to complete nearly all of your DIY jobs. The 8-inch wheels are more tailored to industrial-sized tasks. These can be found in massive metal-working shops where heavy pieces of iron need to be buffered and refabricated on a regular basis.

Grinder Wheel Materials

Although your bench grinder is going to come with a set of wheels, you are probably going to have to buy extras to see you through all of your various applications. Plus, different grinders will come with different wheels. It’s important to keep a variety on hand to ensure you get the job done right, assuming you will be using the bench grinder for more than one scenario.

If you are grinding steel, make sure you get an aluminum oxide wheel. This will make grinding steel quick and painless. For cast iron, you want a silicon carbide type of wheel. Materials which are brittle, hard, and a little crusty will need to be grinded using a soft wheel with fine grit. On the flipside, soft materials will need the opposite, a wheel which is hard and has coarse grit.

Types of Grinder Wheels

There are many types of grinder wheels that will work great on your bench grinder. The most common of which is the straight wheel. This wheel is general purpose for a lot of different applications. You can use it to do any menial task, such as sharpening blades, chisels, screwdrivers, and other metals. You can also use a straight wheel for grinding rough metal surfaces.

A cylinder wheel is used only with vertical and horizontal bench grinders. It is a hollow wheel up to an outstanding 12 inches in width. The cylinder wheel is utilized in flattening surfaces, turning an uneven piece of material into something flat.

If you need to be grinding threads on adapters or other threaded pieces, or you need to grind teeth in gears, then you want to pick up a tapered wheel. The wheel is tapered near the edge, which allows you to get close and personal for delicate grinding on thin, misshapen, or generally strange pieces. This wheel is crucial if you are buffering small components for mechanical systems.

There are specialty wheels available which are much less common. These include cut-off wheels, diamond wheels, and saucer wheels. However, the uses of these are incredibly niche and it is unlikely you will need these in your toolbox. Also, diamond wheels can be incredibly expensive. For home DIY jobs and hobby applications, a straight wheel and taper wheel will suffice. Plus, every bench grinder should come with a bristle wheel for light cleaning of materials.

Budget & Brand

Budget often means brand. If you know how much money a good grinder is worth to you, it will allow you to do better targeted buying. Some brands are more expensive than others, but this is because they’re better quality. Check out our list above for which brands are offering the best, what their features are, and what the price is when buying online. Sometimes it pays in the long run to spend a bit of extra dough.

Chances are you already have a brand that’s your favorite when it comes to buying tools. If you don’t, make sure whichever brand you go with is reputable. Try to stick with a brand that is on our list, since these are the best bench grinders on the market. You also want to ensure the brand is going to give you a quality replacement warranty. Most trusted tool manufacturers offer lifetime warranty on all their products, from cordless drills to mounted bench grinders.

Reviews & Deals

Once you have shortlisted a few of the bench grinders, compare the product reviews online. These can be imperative to seeing what kind of experience other workers had with the tool. Also, keep your eyes open for deals. You can often find jaw-dropping deals and discounts from the top sharks in the business, bringing their price down to meet the competition’s lesser models. As a side note, keep your eyes open for bench grinders that come included with a variety of wheels, since this can save you the hassle of buying them yourself. And while all the best bench grinders are going to be safe, it pays to do an extra bit of digging to discover the safety track record of your chosen unit before buying. You can never be too safe.
