A bench grinder is utilized to drive an abrasive wheel for proper grinding of the wooden job. If you are a pro-grade woodworker, then you might be aware of the common grinder types that are mostly used for hand grinding of different cutting tools or shaping any rough wooden project or others.
As the bench grinders are typically found in the woodshops fixed to the benchtop, it is not at all flexible in terms of portability. You have to bring the desired workpiece to it to work on. However, the ones who prefer the portable ones, go for the angle grinder model.
Note: The best part of the grinder machine is you can replace the existing wheel on it with a buffing wheel or wire brush wheel, as per your purpose (like cleaning or polishing tasks, etc.). Also, the stiff abrasive wheels can be utilized to neat and rough metal or wooden edges and more.
Although there are numerous bench grinder models available in the market, we have compiled a list of the finest quality benchtop grinders in the article. Every model has been discussed in brief followed by their respective pros and cons.

Buyer’s Guide: Things to Consider While Buying a Bench Grinder
The professionals often pay attention to the grade and bond of the abrasive grinder wheel as it is the main part of the entire device. Based on its type, it is either used for shaping jobs, or sharpening any cutting tool, including chisels, bits (for drilling), tool bits, for sharpening cutting tools such as tool bits, drill bits, chisels, and gouges.
Moreover, the device finds a major part of its application in the metal industry as well, for rough metal shaping prior to fitting or welding tasks.
However, if the buffing wheel is made of steel, then it is recommended not to use it on any softer metal, like Aluminium. Else, it may lodge the softer metal particles to the pores of the buffing wheel, which in turn will expand due to the heat produced from grinding action. Thereby, the expanded particles of the wheel may eventually dislodge causing injury. On the other hand, the wheels with vitreous property are usually found in most grinder machines, where the wheel has an inherent risk of cracking after little use only.
That was general consideration. Now let’s check out the point-wise description of the considerable factors:
Bench grinders have a wider range of applications you could possibly think. Although this benchtop tool is mostly used for sharpening blunt cutting tools or metal pieces, etc., others find it a widely useful tool in the woodworking industry. So, this device is definitely worth investing in. Talking about its specific application, this device can serve you with multiple types of buffing potential that you could think of.
Almost everything- starting from bench grinders to plumbing work, from cutting pipes to grinding the same to the required length, or simply to neaten and smoothen burned metal edges, buffing rough patches, etc.- can be conducted smoothly with a bench grinder. Plus, it works irrespective of any material type being used, be it a metal or plastic pipe, task implementation is faster and easier, and significantly minimizes the hassle of any DIY project enthusiast.
If you are about to repaint your home interior and want that job to be done ahead of time, a bench grinder can be used. You can utilize it as a sanding machine and as the grinder motor rotates at a higher speed, it automatically speeds up the entire task. Besides, it smoothens the rough portions of the wall and removes old layers of paint at much higher speed.
Coming to the woodworking part, bench grinders can be used in precise buffing works that need detailing. That means smoothening of floorboards, just as done with a sander, or to level out the furniture joints are done more efficiently. From the flooring point of view, a bench grinder is a perfect tool for removing grout from the gaps of the floor or wall tiles for further regrouting.
If you are thinking that the bench grinder is the sole device for home application, then it is not. Though it is an excellent tool for the DIY home users, sometimes situations would require an alternative product. This is typically concerned with the space or gap factor as the bench grinder, being a bulkier grinder type, takes up considerably more space compared to what its alternative types tend to. Two alternative grinder types are there; the die grinder and the angle grinder types.
Die grinder types are the handheld power devices like Dremels. These are portable cum small rotary machines, perfect for conducting small scale sanding and buffing of plastic, metal, or wooden jobs. Such a type of grinder is suitable for implementing any intricate task that needs much detailing, like sculpting or carving on a varied range of material surfaces. They neither have the scale nor have the power like a bench grinder, but are smaller and perfectly suited for precise detailing work.
Angle grinders are another type of handheld device. But it is way larger than the previously discussed grinder type. Still, this type is the better intermediary between bench and die grinders as the angle grinder offers both portability (as in die grinder) and large coverage of grinding surface (as in bench grinder). Consequently, it is a two-in-one grinder tool for conducting large scale work efficiently. Conversely, angle grinders are not an ideal choice for detailed work or engraving which better suit a die grinder, but are efficient. Also, maybe more portable but not as versatile or powerful as the bench grinders.
If there is enough space in your workshop or home, then pick the bench grinder at the first preference as it is the best bet concerning versatility and power, rather than considering the handheld alternatives. The space could be an issue, however, as bench grinders are heavier and bulky, it would require enough room for placing a sturdy workbench to install the grinder upon.
The crucial part of the bench grinder is the wheel, which is driven by the grinder motor. Its abrasive surface effectively grinds the rough metal, plastic or wooden surface. However, what material surface is to be buffed depends upon the wheel size, shape, and the material it is made of. These factors are the must to consider while picking a grinder model as it has a major effect on the performance of the bench grinder and the conditions it is suitable for.
The “size” of the bench grinder indicates the diameter of the wheel. Although a variety of sizes are available in the market, the 6 inch and 8 inch bench grinders are the two most widely used grinder models. While the one with 6 inch grinding wheel is sufficiently powerful and large for home use and most DIY tasks, the 8 inch wheel based bench grinder are generally used by the professionals, however, this model is also perfectly fit for home use. The 8 inch bench grinder is larger and hence heavier than the 6 inch counterparts. Thereby, the workbench for the 8 inch one occupies more space for comfortable functioning of the device.
The types of material involved in making the grinding wheels are also significant. Different materials have different properties, and that relates to the type of materials the grinding wheels are best used for. For instance, a wheel coated with silicon carbide is the best ground for cast iron buffing, whereas the Aluminium oxide grinding wheel is best for buffing steel objects.
Concerning the shape, the straight wheels form a major category of the grinding wheels available in the market. The straight wheel based tool is used in simple edge straightening tasks to fine leveling of a flat surface. Apart from that, there are tapered wheels on which the edge of the wheel is tapered towards a tapered rim. Such a type of wheel is ideal for sensitive grinding tasks, like teeth gearing or thread screwing in teeth, as the smaller edge ensures better control over the gum. The cylinder wheel is the third major grinder wheel type. It is a hollow, wide wheel, covering a greater grinding surface. This wheel design makes it fit for grinding large, flat surfaces, however, it hardly ensures precise control over grinding.
Other wheel designs available in the market include saucer wheels, diamond wheels, and cut off wheels. Bench grinders with any of these wheels are seldom used in home application, and are commonly found in professional kits only, as these specialty wheels are limitedly used for very specific applications.
If you made it this far, here are the top picks:
- DEWALT Bench Grinder 6-Inch (DW756) has user convenience and has a fast cum robust electric motor to smoothly drive the grinding wheel for buffing any material type; be it metal, wood, or others. The all-in-one package makes this the leading bench grinder model on the list.
- Rikon Professional Power Tools 80-805 is meant for professionals to whom the performance and work output matter, but not the high budget. The durable tool rest makes the task comfortable for the user and the rubber feet maintains the tool stability and reduces vibration during operation.
- Metabo DS 200 8-Inch Bench Grinder produces minimal noise and is easy to use, however, the model is not for the tenderfoots, plus short-lived tool rests make it the third preference on the list.
