Metalworking is a challenging and rewarding hobby, but it requires the right tools to get the job done. One essential tool for any metalworker is a grinder. In this blog post, we’ll take a closer look at grinders for metalworking and what to consider when purchasing one.
What is a Grinder for Metalworking?
A grinder for metalworking is a power tool that uses a grinding wheel to remove material from a workpiece. The grinding wheel is typically made of abrasive particles that are bonded together to form a solid disk or wheel. Grinders can be used to shape and polish metal surfaces, remove rust, and sharpen tools.
Types of Grinders for Metal
There are several types of grinders for metalworking, each with its own unique advantages and disadvantages.
1. Bench Grinders
Bench grinders are the most common type of grinder for metalworking. They are designed to be mounted on a workbench and are powered by an electric motor. Bench grinders typically have two grinding wheels, one coarse and one fine, that can be used for different types of metalworking tasks.
2. Angle Grinders
Angle grinders are handheld power tools that are used for cutting and grinding metal. They are versatile tools that can be used for a variety of metalworking tasks, including cutting, grinding, and polishing. Angle grinders are available in different sizes and with different power ratings, so it’s important to choose one that is appropriate for your needs.
3. Die Grinders
Die grinders are similar to angle grinders but are smaller and more precise. They are often used for detailed metalworking tasks such as shaping and polishing. Die grinders are available in electric and pneumatic versions, with the latter requiring an air compressor.
Factors to Consider When Choosing a Grinder for Metalworking
When choosing a grinder for metal for working, there are several factors to consider:
1. Power
The power of the grinder is an important factor to consider, as it will determine how quickly and efficiently you can work. Bench grinders typically have motors that range from 1/3 to 1 horsepower, while angle grinders can have motors that range from 4 to 15 amps.
2. Size
The size of the grinder will also affect its performance. Bench grinders are available in different wheel sizes, typically ranging from 6 to 10 inches in diameter. Angle grinders are available in different sizes as well, ranging from 4 to 9 inches.

3. Speed
The speed of the grinder is another important consideration. Bench grinders typically run at a slower speed, around 3,500 RPM, while angle grinders can run at speeds of up to 11,000 RPM. Higher speeds are better for cutting and grinding, while slower speeds are better for polishing and sharpening.
4. Wheel Type
The type of grinding wheel you choose will depend on the metalworking task you are performing. Wheels made of aluminum oxide are ideal for grinding and shaping, while diamond wheels are better for cutting and polishing.
Angle grinders are an essential tool for the metalworking, but with so many options on the market, it can be overwhelming to choose the best one for your needs. In this blog post, we’ll take a closer look at 10 of the best angle grinders for metal.
