Both bench grinders and angle grinders could be handy for a certain project that you’re working on. But how can you determine which alternative is the best fit for your task?
Our article aims to solve this confusion by comparing bench grinder vs angle grinder in detail to help you make a well-informed decision.

Differences Between Bench Grinder vs Angle Grinder
Despite coming from the grinder family, the two types of power tools are significantly distinctive.
1. Design
Their designs are considerably different.
Angle grinders have a handheld design to fit comfortably in your hands and for easy control. They include a grip to maneuver easily into tight corners and to reduce vibrations. This grip adds additional support to your handling and acts as a vibration dampener.
On the contrary, bench grinders are power tools sitting on top of your workbench and using an abrasive disc for cutting workpieces. It’s designed to stabilize on a level surface as well as to minimize vibration. When using a bench grinder, you have to bring your workpiece to it.
2. Function
Even though both power tools are grinders and can be utilized for grinding, they are not identical.
Bench grinders are ideal for sharpening dull tools, modifying the size of workpieces, and restoring old rusted items. When you need to sharpen an object and the task requires both hands to obtain the correct edge, a bench grinder is suitable for your job. For example, it is the ideal sharpening tool for lawn mower blades.
You can also utilize bench grinders to shape, hone materials, as well as remove burrs in casting. By switching between different disc types, you can use them for sharpening, polishing, shaping, and cleaning any form of metal.
On the other hand, angle grinders are extremely versatile and have a wide range of applications. They can cut various materials and are frequently utilized for metal because they are strong enough to cut through this material.
Other applications of angle grinders include polishing wooden objects, removing mortar from bricks, and sharpening the edges of certain instruments. They can also clear dust from old metal objects.
3. Flexibility
Because angle grinders are portable power tools that can tackle a wide range of tasks, they have far more uses than bench grinders. Since the latter is immobile, you must work around them.
As a result, bench grinders are less flexible and are unable to perform some tasks. On the other hand, angle grinders can operate from a number of angles, thus they can manage a greater range of applications.
4. Speed
Regarding speed, angle grinders are considerably faster than their bench alternatives. The former typically has a disc speed ranging between 8,000 and 12,000 RPM, while the latter’s wheel speed is from 3,000 to 3,500 RPM.
The former is lightweight and portable, making them an excellent choice for quick jobs. Small cutting tasks can be completed in minutes, allowing you to get more done in less time. By contrast, bench grinders don’t cut as quickly but they are far more precise.
5. Vibrations
When operating any tool, you’ll almost certainly experience some vibration as a result of its power and speed. Nevertheless, angle grinders vibrate significantly more in comparison to bench grinders.
Since bench grinders are designed to be used on a level surface, the weights of both these grinders and the level surface work together to minimize vibration. By contrast, angle grinders are portable power tools, which makes them less stable.
The exact degree of vibrations will certainly vary depending on the model and the materials you’re operating on.
6. Wheels
There are generally 2 rotary discs in bench grinders. Both of them can be attached and utilized at the same time. This is different from angle grinders because they can only utilize one disc at a time.
Even though the difference is little, the fact that bench grinders having two discs saves time by eliminating the need to change discs, compared to using angle grinders.
7. Weight
The bench grinders are certainly heavier than angle grinders. Since the latter are handheld power tools, they must be lightweight, varying between around 7 and 8 pounds.
On the other hand, bench grinders are heavy due to their cast iron base, which helps them stabilize in position.
8. Portability
The last distinction between the two power tools is their portability.
Angle grinders are lightweight handheld tools with an approximate weight of 8 pounds. Their compact size allows you to easily grip and maneuver them while completing small projects.
On the contrary, bench grinders are stationary machines that position on the surface of a workbench and let you manipulate the materials that you are operating on rather than the power tool itself.
Because of this distinction, angle grinders are frequently carried to a job site, whereas bench grinders are used in workshops.
