Angle grinders are powerful tools to grind, cut, and polish metal and other hard materials. They are used in many fields, such as construction and auto repair. Angle grinders can be powered by electricity or by petrol engines. They are available in corded or cordless models and in different sizes and weights.
Angle grinders have been around since the 1950s but have changed significantly. Today’s angle grinders are much quieter than older models, making them safer for use in residential settings. They also generate less dust than older models.
Angle grinders come in many different sizes and shapes, so you can choose one that fits your needs best. There are several different types of angle grinders based on their power source: electric, pneumatic (air-powered), or gasoline-powered engines. If you want to use an angle grinder often or for long periods, opting for one with an air compressor is best. These are more durable than cordless models, which require charging every few hours before continuing work on a project!
We’ll go over each type of angle grinder in this article and explain what makes them unique. We’ll also outline some of their benefits so that you know when to use each type.
Types of Angle Grinders
Angle grinders are essential for anyone who needs to work on their car or do some home repair. They’re also great for getting into tight spaces and working on hard-to-reach items.
There are several different types of angle grinders, but the most common are:
1. Cordless Angle Grinders
Cordless angle grinders are battery-powered, so they don’t need to be plugged into a power outlet. This makes them ideal for contractors who need to move around while working or for homeowners who want to use the tool in their garage or on the deck outside. Cordless angle grinders can also be used anywhere there is an outlet nearby—you need to bring along a battery pack and charger. They’re often lightweight and compact, which makes them easy to carry around. In fact, some cordless models even come with built-in lights so you can see what you’re doing without having to stop working!
2. Corded Angle Grinders
They have a rotating disc powered by a high-speed motor that turns at about 10,000 rpm. These are usually powered by an electric cord, which means you’ll need to be near an outlet or extension cord to use them. The cord can also cause problems working in tight spaces or getting into hard-to-reach areas.
The upside is that corded grinders are more powerful than cordless models, so they can tackle tougher jobs like cutting through metal or concrete. If you need something with more power than a handheld drill but want to save money on something other than an industrial-grade tool, this might be the perfect option for you!
3. Pneumatic Angle Grinders
Pneumatic angle grinders are a type of angle grinder that uses compressed air to power the tool. These tools are used for cutting and grinding in many industries, including woodworking, metalworking, and plumbing.
Pneumatic angle grinders are typically less expensive than their electric counterparts because they don’t require an electrical outlet. They also produce less heat than electric models, making them safer for use around flammable materials.
In addition to being safer around flammable materials, pneumatic angle grinders are more portable than electric models. This makes them ideal for use in confined spaces where other power tools cannot be used safely or effectively.
4. Variable Speed Angle Grinders
Imagine a grinder that could change speeds, allowing you to work in any situation.
That’s the idea behind variable-speed angle grinders. A variable-speed grinder is a powerful tool that can be used for various jobs, from woodworking and metalworking to stone cutting and polishing. It’s an ideal tool for the craftsman who wants to do it all.
The great thing about this kind of grinder is that it allows you to adjust the speed with which it rotates. This means you can slow down or speed up depending on your project’s requirements and how much power you want behind each stroke. The slower speeds are typically used with softer materials like wood or plastic. In comparison, faster speeds are better suited for tougher materials like steel or stone.
5. Straight Angle Grinders
Straight-angle grinders are one of the most versatile on the market. They’re ideal for grinding the outer edges and inner parts of pieces, sharpening blades, and cutting through metal.
A straight-angle grinder is positioned at a 90-degree angle, so it can be used horizontally and vertically. This allows you to get into hard-to-reach places easily—and in no time!
With these tools, you’ll be able to work faster than ever before and achieve better results in less time.
Benefits of Using Angle Grinders
Portable and easy to use
You can use an angle grinder for everything from sanding to cutting metal, so it’s important that it’s easy to take with you wherever you go. That’s why they’re so popular with professionals—they can throw them in their toolboxes and take them anywhere. They’re also compact enough that they don’t take up too much space in your garage or workshop.
Angle grinders are versatile tools that can be used in various applications. One of the main benefits of angle grinders is that they can handle a wide range of materials, including metal and wood. They’re also great for shaping and polishing metal and can be used for grinding concrete and brick. Angle grinders are relatively easy to use, making them ideal for home projects where you don’t want to invest in an expensive tool that requires professional training.
Safe to use when operated correctly
This is because they have a protective guard that covers the motor, preventing debris from getting caught and causing an electrical hazard.
They also have a safety trigger that prevents the disc from spinning unless you squeeze it. Suppose you accidentally turn on your angle grinder without having it secured or drop it. In that case, there’s no risk of injury—the grinder won’t start until you’re ready to use it!
Cut, grind, and polish with ease
Angle grinders are the go-to tool for cutting, grinding, and polishing metal. Because they have a hand guard that protects your hand from flying sparks, they’re safe to use around other people—but they can still get the job done quickly.
An angle grinder can cut through sheet metal up to 1/4″ thick. That makes them ideal for construction workers who need to remove stubborn metal or make a hole in something for a new pipe or conduit. You can also use them for grinding down welds on your car or removing rust from tools. Angle grinders are also great for polishing metals like aluminum or brass because they generate very little heat compared to other power tools like routers and drill presses.
They offer an ergonomic design
One of the most important benefits of angle grinders is their ergonomic design. Angle grinders are designed to be comfortable, especially when using one for long periods. The handles are well-constructed and have a soft rubber grip that offers a secure hold. You can also choose between a right- or left-handed models, which is helpful if you have a dominant hand and want to make sure you buy a model that works best for your needs.
Wrapping It Up
Angle grinders are versatile tools you can use for various tasks. They’re great for removing rust, smoothing out rough edges and surfaces, preparing metal for welding and joining, and removing paint or other coatings from surfaces.
They’re also helpful in some other situations:
- Using them to cut through drywall to make an access hole.
- Grinding down old concrete walls to create a smooth surface for new tile installation.
- Even polishing your car with one.
If you’re looking for something to help make your life easier around the house or on the job site, angle grinders are an awesome choice!
