Buyer’s Guide to Angle Grinder

Consider the following When Purchasing an Angle Grinder

Angle grinders differ differently from dying grinders, giving them various benefits and making them more suitable for particular applications. You can use Angle grinders for rough grinding and cutting; die grinders are small rotary tools used for precise work. A thin abrasive disc is attached to a revolving spindle positioned at a 90-degree angle to the tool’s body.

It’s easy to be overwhelmed by the abundance of options and perplexed by the variety of functions available when shopping for angle grinders online or in your local hardware store.

Trying to choose which grinder features to consider is where our buyer’s guide comes in helpful. To assist you in making an informed selection, we’ve listed and discussed things to consider when purchasing the best angle grinder for your requirements.

Motorized Motion

In general, the larger the engine output, or horsepower (HP), the more power the motor produces, letting you cut, grind, or polish faster. The price of an angle grinder will increase in direct proportion to its size. Smaller hand-held angle grinders generally feature engines rated at 1.5 to 5 horsepower.

Size of the Disc

The disc size is a critical aspect to consider when purchasing an angle grinder. Smaller versions generally use a 4.5-inch disc but may accept a 5-inch disc on occasion. Angle grinders with a larger disc accept a seven or 9-inch disc. Unsurprisingly, different sizes have their advantages and disadvantages.

Hobbyists and do-it-yourselfers prefer smaller angle grinders. Models with a 4.5-inch disc are reasonably light and maneuverable in tight areas. Despite their compact size, they are strong enough to complete most of your jobs, including grinding, sanding, and sharpening. This size is available in various corded and cordless versions to suit your requirements around the house, yard, or garage.

Angle grinders with a larger blade are more powerful and ideal for vehicle maintenance and heavy renovation tasks. When cutting through concrete, steel, or other rigid materials, a seven or 9-inch disc size and higher power are advantageous. Typically, these devices are corded to produce additional force.

Source of Power

As is the case with many other power tools in your workshop or garage, you have two basic options when purchasing an angle grinder: corded or cordless. While pneumatic angle grinders are available for purchase, they are usually not utilized by the ordinary do-it-yourselfer because you can use it in professional car body shops.

Due to their reliance on alternating current from the outlet, corded angle grinders provide constant power – generally more than cordless versions. They encircle you physically and may need the use of a heavy-duty extension cord. When operating with the tool, the cable might be an annoyance or a trip hazard.

Cordless angle grinders are advantageous while operating in confined spaces or locations without access to an electrical outlet. On the flip side, they lack the power of corded versions, and their power output and speed may diminish as the battery empties over time.

When shopping for a cordless angle grinder, bear in mind that the battery comes separately. If you want to have more than one battery on hand for projects, search for an angle grinder compatible with your other cordless power tools.

Arbor Dimensions

On an angle grinder, the arbor, also known as a spindle, is the component to which the cutting disc or grinding wheel is attached. In the United States, the majority of angle grinders feature a standard 5/8-11 arbor. It equates to a 5/8″ diameter spindle with 11 threads per inch. Some versions have a 7/8″ spindle, so the arbor size must match the wheel’s or disc’s diameter. There are adapters available to convert a 5/8″ arbor to a 7/8″ arbor and vice versa.

Speed

Another critical grinder characteristic to consider is speed. The speed at which an angle grinder’s disc rotates measures in RPM, or revolutions per minute. A greater RPM indicates that a tool can cut more readily and swiftly through the target material, completing the operation faster.

Angle grinders with a smaller blade rotate at a faster pace than their bigger equivalents. They generally work at rates ranging from 5,000 to 11,000 revolutions per minute. Smaller tools may also include variable speed controls that allow you to customize the RPM to your project’s requirements.

Angle grinders with a larger blade rotate at slower maximum speeds, generally between 5,000 and 8,000 revolutions per minute.

The speed indicated on the angle grinder represents the highest RPM possible while the tool is not “laden,” when it is not equipped with a disc and is not actively grinding or sanding. As a result, once in use, the speed will decrease slightly. Additionally, keep in mind that when a disc spins faster, it grows hotter.

Controllable Speed

Variable speed control is a convenient feature to have if you want to use your angle grinder for various applications. Adjusting the speed is advantageous for polishing or buffing materials using the tool. Variable-speed models are less popular and more expensive, but they allow you greater control over the RPM and spinning speed while in use.

Protection Against Dust

Dust accumulation inside the internal components of an angle grinder over time can block the vents, resulting in overheating and perhaps burning out the engine. Additionally, this dust accumulation might cause the gears to wear out more quickly. It makes dust protection critical, even more so when operating the angle grinder for extended periods.

Specific versions have dust protection measures such as a seal or a dust ejection mechanism that keep dust out of the vents and away from the motor’s internal workings. These qualities prolong the tool’s life, obviating the need to replace it soon.

Brake Against Kickback

A kickback brake is a critical safety element on an angle grinder, ensuring that the wheel comes to a complete stop extremely fast in the case of a bind-up, stall, or pinch. The tool is prevented from escaping and kicking back at the user by halting wheel movement, causing severe injury.

Trigger with Two Stages

Certain angle grinders include two-stage triggers, another safety feature that helps prevent damage or injury to the operator. Before using the tools, the separate safety switch must be disengaged using a two-stage trigger. It reduces the likelihood of the angle grinder starting unintentionally while you are replacing the disc.

Start Mildly

Angle grinders frequently recoil when turned on due to their fast, strong motors rapidly approaching maximum speed. Recoil may force the angle grinder to leap into the user’s hands, posing a significant harm risk. A soft start on an angle grinder minimizes recoil at start-up by gradually increasing the power output until the grinder reaches full speed.

Guard of Safety

Angle grinders come fitted with a safety guard to protect your hands from the disc during operation, prevent debris and sparks from flying towards your face and body, and protect surfaces in confined places from damage. When using an angle grinder, the safety guard may be moved or set and covers half of the disc, allowing you to see the work area.

Moveable guards are more common since they can be adjusted for right or left-handed or you can use it to protect against flying debris. They do, however, have the potential to fall off the angle grinder if not correctly tightened.

Fixed safety guards are more sturdy and hence provide superior protection. Additionally, they provide no risk of slipping off the grinder after adjustment.

Noise

Unfortunately, angle grinders are naturally noisy, and you should always use them with adequate hearing protection. When working, an angle grinder produces around 110 decibels. Certain manufacturers, like DeWalt, have developed unique gearcases that include perfect gear alignment for a smoother, slightly quieter operating experience.

Thermal Shielding

Thermal overload protection is beneficial for any motorized instrument or piece of equipment, and an angle grinder is no exception. Thermal overload protection, sometimes referred to as thermal cut-out, is a safety mechanism that shuts off the motor when it exceeds a predetermined temperature. It protects the motor from overheating and perhaps burning out. Once it has cooled sufficiently, you may restart the tool and continue working.

Conclusion

Best Angle grinders are very flexible hand-held power tools that you can use to do various jobs around the house or workplace. They are slightly more powerful and more significant than die grinders and are ideal for cutting metal, rebar, stucco, and tile. Additionally, you can use an angle grinder for sharpening, sanding, and polishing.

While an angle grinder is an excellent addition to any tool collection, it’s critical to understand the many features available to select the finest angle grinder for your requirements.
