Things To Know Before Buying a Best Angle Grinder
The grinders have many things in common. When you go looking for the grinder that works for your needs, do your homework and make sure you know the following things about each grinder you consider.
- Power Source
There are two different ways your grinder can come. Your grinder can come with a power cord for a continuous stream of power and voltage, or it can come with a battery. Both types of grinders have their benefits. The corded grinder you will never need to charge or worry about the batteries burning out. You will always have power, and you will never need to stop working to wait to charge a battery.
The battery-powered grinders will never get in your way because of a cord, and if the battery is at least eighteen volts, you will be able to use it until your battery requires recharging. Most batteries that come with cordless power tools will be quick-charge batteries, so you don’t’ have to wait long for them to recharge and for you to keep going. They are easy to store, with no cord to wrap up, and easy to travel with for those out-of-the-home jobs.
- Disc Size
Most grinders come with multiple types of discs so you can select the size and shape that works for your project. Before you buy your grinder, make sure you know which sizes are available for you to purchase separately if you need them. A grinder without a lot of sizes to choose from will limit your projects, and you will spend more money to purchase a separate grinder to get those projects completed.
- Watts
There are rated watts and running watts. You should know what kind of watts each grinder has when comparing them. The watts your grinder has will tell you about how much power you have to work with for each project you undertake. The higher the watt rating, the more power the grinder has.
A higher rating for watts does not mean the grinder will be able to handle massive projects or excessive use. Other factors will go into how well the grinder performs in the long run.
- Speed
How fast your grinder goes depends on the type of project you are working on. It is also an important factor in how your grinder performs. Most grinder speeds average up to ten thousand rotations per minute though low-end grinders will only average five thousand per minute. The higher speeds can help get the results you want more quickly if you have the skill to control the grinder while it is in operation.
The faster grinder is not always the best, especially for an inexperienced beginner, as you can damage what you are working on because you cannot control the tool with the speeds produced. The grinder you should work with is a variable speed grinder.
A variable speed grinder allows you to operate at the speed that works for the piece, but also the experience level. When you go looking for a grinder, you should make sure your new grinder has this feature to ensure you have full control over the piece and your advancement.
- Ergonomic Design
Having a tool that is ergonomic in design means it will fit your hand comfortably and ensure you will be able to use it for hours or even days without hand fatigue. Ergonomic tools help are comfortable for the human hand to use and helps keep you working long-term.
Buying a tool from a major manufacturer that has ergonomic features is not something to sneer at. It is worth paying the extra price for a tool you can use without hand, shoulder, or back fatigue, and it should be a deciding factor in the tool you finally select.
- Hand Protection
Many manufacturers are working to make their tools safer and as well as easier to use. A grinder with a hand guard is something to consider when getting deep into projects. A hand guard protects your hands and even your face from splinters and other debris; the grinder can kick up. While not a necessary feature to get your job done, a hand guard is a feature that is becoming more standard on some tools for safety, and it is a good thing to have if you are beginning your work with a grinder.
- Dust Protection
Dust can kill your power tools. The grinder is no exception to getting dust on it and in it. Many modern grinders come with dust shields and designs that protect the grinder from getting sawdust and regular dust inside the motor. If you do get dust inside the motor of either kind, it will burn out or, at the very least, shorten the lifespan of the tool.
Most grinders come with special protection to ensure dust does not get inside the delicate engine. The design includes special components that funnel dust away from the engine and any moving components that can trap dust inside of them.
- Slow Start
Depending on the grinder you buy, it may or may not have a slow start. A slow start is a good feature to have on a powerful grinder that is putting out over ten thousand rotations a minute because it allows you to get the grinder under control before the higher speeds get going. The slow start is also a safety feature that will prevent you from damaging yourself or your project so you can accelerate the speed and power of the grinder as you get going.
- Price
Grinders come in a wide range of prices, but the price is the last thing you should look at when considering what grinder to buy. While an expensive grinder can break your budget, the features you need to do multiple projects are what you are buying. In some cases, you are also buying the longevity of the tool.
Most grinders you will get a reasonable price, and they come with many features you would want on a grinder such as variable speeds or dust protection. You can find a decent grinder that will last you through multiple projects without breaking your budget.
