Buyer’s Guide – Considerations When Choosing an Angle Grinder
Features to Consider When Choosing an Angle Grinder
Typically only shown on a large angle grinder, the horsepower on a nine-inch grinder can be more than 5 hp making it a pretty powerful hand tool. Just to give you a good comparison, that is the same amount of horsepower you would get in a large gas lawnmower.
This is the measure you would normally see in a 4 ½-inch angle grinder. Amperage will tell you what the electrical load is on that motor. But for our intents and purposes, consider the more amps a grinder has, the more power you have to work with. Typical DIY grinders will start around four amps, but six amps are the suggested minimum. And, if you have a grinder with over 10 amps, you have a very powerful tool, which is probably the most anyone will ever need.
You don’t often see wattage listed on an angle grinder. It is a good rating of the output of the motor’s power and also follows the rule of more is better.
Known as the rotational speed of the grinder’s wheel. You will see a difference between small and large angle grinder with larger models feature fewer RPMs while smaller tools will give you more.
The larger the angle grinder, the heavier it typically is. A nine-inch grinder can weigh as much as 12 to 16 pounds, which makes them a great choice for professional applications. Smaller models can be found between 4 and 5 pounds, which is a nice lightweight for DIYers. Don’t go any lighter than that or you may be risking cheap components that can break easily and will also not help steady and balance the grinder.
There is a large range of angle grinder wheels that include chainsaw-like devices that allow you to carve tools, lambswool bonnets that polish auto bodywork, and diamond-encrusted wheels that are used for cutting tile.
It’s very important that you using the correct wheel for the application. A steel grinding wheel gets clogged in stone, and it also won’t put a scratch on metal bolts. Remember that a shattered wheel can be very dangerous.
DIYers usually prefer an angle grinder that takes 4-1/2-inch discs. These are small and lightweight grinders that you can use in a small space, but still have the power you need for most sharpening, grinding, and sanding jobs making them a great choice for uses around your home.
An angle grinder that takes a 7 or 9-inch disc is more powerful as well as heavy and more difficult to maneuver, especially in a tight space. These are good choices for large remodeling projects and auto repair. Professionals will need the largest angle grinder available to maximize their power and size to cut through hard materials like steel and concrete.
The size of an angle grinder can vary by a few inches in length, although the size doesn’t have much impact. But an angle grinder that has a more slender motor housing will be easier for users with small hands to use.
An angle grinder will start up fast and generate a good amount of kickback, which may cause them to lurch in your hand as you pull the trigger. With a soft start feature, your angle grinder will have a design that reduces that motion.
On some angle grinder models, you will find a lock-out switch or button that will stop the unit from starting accidentally.
If you look at a cheaper angle grinder, you will find gears that are made out of hard plastic or nylon. Since a lot of power will be transmitted through these parts, it’s preferred to have metal gears instead.
Many angle grinders break down due to debris and dust getting inside the motor and the gears. Look for angle grinders that have a design or system that prevents this from happening.
