Things to Consider Before buying a Variable Speed Angle Grinder
The power of the motor determines how quickly you can work. Without enough AMP in the motor, the grinder will not be able to achieve the speeds necessary for heavy-duty applications.
Variable speed angle grinders typically have powerful motors that can produce maximum speeds of 10,000 RPM.
Angle grinder tools with large discs are associated with more heavy-duty applications. If you have a 4 1/2 inch or 5-inch disc, you are most likely working with more delicate work.
Choose a disc size based on your specific model. You should not use a bigger disc than the one specified for that grinder.
Speed is measured in rotations per minute or RPM. Check that your angle grinder tool can deliver the speed you need for your application.
Variable speed angle grinders give you the option to select a specific speed. However, speed is only as good as the motor on this type of tool.
If you can choose a model that does not use brushes in the motor, you will not need to spend time replacing them. Otherwise, motor brushes eventually wear out and need to be serviced to avoid motor damage.
Safety is important when dealing with a dangerous, fast-spinning tool like an angle grinder. Look for a model that has adjustable wheel guards and soft start mechanisms.
Some tools even have mechanisms that prevent kickback in the event of a stalled or pinched wheel.
Comfort and Control
The handles on any angle grinder should feel natural for you to hold. Handle grips sometimes are over-molded for a more comfortable, ergonomic feel.
Control can also be enhanced on an angle grinder if it is equipped with vibration control. Look to see where the switches are located on any model because these will be used a lot.
Drive diameter pertains to the diameter of the disc for the tool. This is the smallest outside diameter of the tool and the part that comes into contact with the workpiece.
Some angle grinders will not be able to fit an accessory with a bigger drive diameter. Take into account your intended use of the tool before looking at the drive diameter.
Angle grinders are usually either electric-powered or battery-powered. If the tool is powered by batteries, you do not need to worry about a cord.
However, you also need to charge batteries between use. An electric-powered grinder is more common. Electric-powered angle grinders require the user to be near enough to plug in to work the tool.
The price of an angle grinder can vary a lot depending on the brand. A very reliable angle grinder tool may cost more than a basic machine.
However, you should focus more on the features and specifications than the price. A very expensive tool will not do you any good if it cannot help you with your work.
A warranty on an angle grinder will give you peace of mind. Warranties usually come from the manufacturer and protect the different components.
This extra is a good option to look for because you can protect yourself from unexpected issues.
What is a Variable Speed Angle Grinder?
A variable speed control angle grinder is a type of angle grinder that has a dial or switch to set the speed. Compared to fixed speed tools, a variable speed tool can run at lower speeds or higher speeds consistently while you work.
If you can choose the speed, you can work on more specific pieces. Different applications may require lower speeds so that you can control the cut.
Other applications may require higher speeds so that you have enough cutting force to get through a material.
When Do you Need a Variable Speed Angle Grinder?
An angle grinder speed control may be most useful if you have a specific application in mind. Sometimes an application requires more finesse and delicateness than you can achieve with a fixed speed tool.
Occasionally, you will also work with a material where you need a little more control. A very fast, fixed speed angle grinder may run away from a user if they are not careful.
Some specific applications that people use an adjustable speed angle grinder for include, wire brush cleaning, sanding, and cutting softer materials. When working with a wire brush, a slower speed ensures that you do not ruin the accessory or burn it up.
At a slower speed, it is also easier to get an angle grinder tool into tight spaces and corners without experiencing a lot of dangerous kickback.
Main Features of a Variable Speed Angle Grinder
Variable speed angle grinders are not as common as fixed speed models. When you are looking to purchase a variable speed model, consider some of the main features that are included.
Some of these features may vary depending on the model. Pick out an angle grinder model that matches your intended applications.
An adjustable speed angle grinder needs to be efficient. If your tool does not have enough power to maintain the constant speed it is set at, then you will spend more time worrying about the speed than completing your work.
The ability to change the speed settings to match a specific application is essential with a variable speed control angle grinder.
A great model will let the user select from several common speed settings that match popular applications.
When you can control the speed on your angle grinder, you still need to have safety features. If you are putting the tool at a higher speed, you should have features like automatic power off and soft start.
A soft start powers the tool on slowly and smoothly so you can reach a high speed after you have control of the machine.
Durability is important for an angle grinder with variable speed settings. Variable speed tools can run through different speeds at different times, which puts strain on the motor.
A well-designed motor will be protected against debris and wear.
Ease of Use
Accessible switches and easy-to-use dials are vital for a variable speed tool. You should check to see if the switches can be turned on or off easily while using the tool.
The dial or controls used to change the speed is also something that should be intuitive and not complicated.
Consider the provided speed settings on any variable speed grinder tool. Delicate work is easily done at lower speeds, but you will not find as many tools with very low-speed settings.
A wide range of speed settings, with four to five stages, is a good place to start.
Motor power, measured in amps, helps determine what things you can accomplish with an angle grinder. A robust motor with a lot of power is essential if your work involves cutting through hard material or lots of polishing.
You can choose an angle grinder with variable speed controls with a variety of wheel sizes. Variable speed settings are not specific to smaller or larger discs.
The difference between the wheel size only matters with the type of work you do.
Ability to Slow Speed
Some angle grinders with variable speed let the user slow the tool down in case of an emergency. This safety feature is not exclusive with variable speed tools, but they are very common with them.
This feature may be a switch that can be easily accessed.
Angle grinders with variable settings are usually consistent. Consistency is an important feature for an angle grinder because rapidly changing speed can mess with your control.
A constant speed setting that does not vary much at all can ensure a smoother cut or polish.
1. What are the Different Types of Angle Grinder?
There are many different types of angle grinders, including tools that are powered with electricity or batteries. Angle grinders can also be broken up between fixed speed and variable speed models.
Fixed speed does not allow the user to maintain a constant speed. Variable speed grinders can be controlled by turning a dial to a specific speed setting.
2. Does Dewalt make a Variable Speed Grinder?
DeWalt makes several variable speed grinders that offer the user the ability to choose a speed. These grinders feature excellent motors with powerful designs. DeWalt pays attention to offering speeds for different applications.
There are also safety features like a trigger switch so that the tool cannot turn on without a series of steps.
3. Do Angle Grinders have Speed Control?
Some angle grinders come with speed control that allows the user to set a dial to a specific speed. Many of these variable speed grinders feature multiple stages of power and RPM to meet common applications.
In many cases, angle grinder tools do not have speed control settings. Without speed control, the user must work with less stability.
4. What does No-load Speed Mean on an Angle Grinder?
No-load speed refers to the speed that a disc on an angle grinder can rotate before it comes into contact with the workpiece.
Usually, this speed is much faster and more powerful. A high no-load speed is an excellent feature, but it should be matched with a powerful motor.
Perhaps one of the most excellent models available for a variable speed control angle grinder is the Makita 9565CV 5″ Variable Speed Angle Grinder. This tool is powered with a 13 AMP motor and lets the user set the speed anywhere between 0 and 10,500 RPM.
The speed setting is controlled with a basic trigger that can be dialed as high as the maximum setting. However, the aspect that makes this grinder special is that the tool combines numerous safety and power features with variable speed controls.
Finding the best variable speed angle grinder is a matter of selecting a tool that anyone can use intuitively. If you cannot pick up on the proper way to change the speed, then the tool will not be very useful for you.
A reliable variable speed grinder can be used for many different applications. Consider what type of work you are most likely to conduct with an angle grinder, and you can find the best model.
