There are wide applications of metal grinding tools from small fabrication units to large automobile industries. Grinding tools can be found from small hardware stores to professional workshops.
There are two types of metal grinders handheld grinders and stationary grinders. Handheld grinders include angle grinders, linear grinders, die grinders, and power drills. Whereas, stationary grinders include bench grinders and belt grinders.
Here in this guide, we will learn everything about the six best metal grinders along with their attachments, their applications, and important factors to consider before buying them.
So, here we go
There are four main handheld grinders available for metal grinding:
Angle grinders are the most important hand tools used for different metal fabrication jobs including cutting, grinding, and sanding. The angle grinder is the most common and multi-purpose grinding tool. The angle in the name (angle grinder) refers to a disc or wheel fitted at an angle to the power tool shaft.
The angle grinders are commonly used for grinding and metal polishing jobs. Manufacturing industries utilize an angle grinder with abrasive wheels to remove unwanted and excessive material from the metal surface. They are also used for surface smoothening, sanding, and metal cutting.
Following are the best angle grinder tools for metalworking applications:
Consider the following important factors before choosing an angle grinder:
A die grinder is a portable cutting tool with a wide range of applications. Die grinding tools are widely used for cutting, grinding, sanding, and polishing metals. This tool also plays a major role in subtractive manufacturing mainly metalworking and woodworking jobs.
Die grinders can grind and cut metals in numerous ways. They can grind with abrasive grains or fine-grit points and can drill with carbide burrs or drill bits.
Die grinders are well-known metal grinding tools used by different metal fabrication industries. They are used to grind and smooth metal surfaces. Apart from metals, they are also utilized for woodworking (wooden cabinets, wood polishing, scrubbing, etc.).
Following are the best die grinder tools for metalworking applications:
First, understand your cutting material before choosing a die grinder. Also, consider the following important factors:
The linear grinder is also known as a flat surface finish or surface conditioning tool. They are blending and polishing machines. Linear grinders smooth down flat surfaces.
A linear grinder is an essential metal finishing tool. They are used to grind metal and other non-metallic materials. This metal grinding tool reduces finishing costs and effortlessly works in aluminum, stainless steel, copper, brass, and other alloys. In linear grinders, there is a thick sanding drum that grinds down metals and creates smooth finished surfaces. Many automobile workshops utilize linear grinders for car surface stripping, sanding, and preparation.
Following are the best abrasive drum wheels used with linear grinders for blending and polishing:
Consider the following important factors while choosing a linear grinder:
A power drill or electric drill is a widely used drilling tool. The electric motor rotates with an attached metal grinding tool such as a spiral band, end brush, or a wire wheel to grind materials fast and smoothly.
A power drill tool can be utilized for both domestic as well as commercial purposes. Power drills can be an effective grinder because they can work in small and hard-to-reach areas where other tools can’t work. They are used to grind and heavy stock removal from stainless steel, aluminum, brass, and other materials.
There are numerous power drill attachments available for metal grinding and they are similar to die grinder attachments. Such as,
Consider the following important factors before buying a power drill:
The two most commonly available and widely used stationary grinders are bench grinders and belt grinders.
Bench grinders are a commonly available grinding tool in metal fabrication and hardware shops. This is a tabletop grinding machine that uses abrasive or grinding wheels to grind materials.
Bench grinders are mainly utilized for grinding, cutting, sharpening, and surface conditioning of other cutting tools (scissors, files, drill bits, and metal cutters). They are used to shape metals and remove unwanted surface materials. In a bench grinder, you can replace the grinding wheel with a wire brush wheel or buffing wheel to clean, buff, and polish your workpiece.
The bench grinder mainly works with two metal grinding tools, grinding wheels and wire brush wheels. Apart from these two attachments, you can also use an unmounted flap wheel with a bench grinder.
Following are the important factors you should consider before choosing a bench grinder for metalworking:
Belt grinders (sometimes called belt sanders) are multipurpose metal grinding tools. Although there are quite differences in belt grinders vs belt sanders. The stationary belt grinder is widely utilized for heavy stock removal, metal cutting, and grinding rough surfaces.
Belt grinders are a flexible tool so they are widely utilized for deburring, polishing, and different grinding applications. They are used to finish, grind, polish, and remove heavy stock materials. Knives sharpening is one of the most common applications of a belt grinder.
The Belt grinder requires an abrasive coated belt to grind metals effectively. Based on size and materials, a wide range of grinding belts is available to fulfill your needs. The common belt grinder attachments are- 2x36 grinding belts, 2x48 grinding belts, 2x42 grinding belts, 4x24 grinding belts. A 2x72 belt grinder attachment is the most popular and widely used by fabrication industries.
Look for the following important factors before buying a belt grinder:
