What to Look for When Buying an Angle Grinder
Angle grinders are slightly different from die grinders, giving them some distinct advantages and making them better suited for specific projects. Angle grinders are designed for cutting and tackling rough grinding materials; die grinders are smaller rotary tools designed for precision work. A thin abrasive disc is mounted on a rotating spindle set at 90° to the tool’s body.
It’s natural to become overwhelmed by too many choices and confused by all of the features offered when looking at angle grinders online or at your local hardware store.
Trying to understand which grinder features you should consider is where this buyer’s guide comes in very handy. To help ease the decision-making process, we’ve listed and explained what’s important to look at when buying the best angle grinder for your needs.
Motor Power
Generally, the higher the engine output or the horsepower (HP) of the motor, the more power output it offers, allowing you to cut, grind, or polish quicker. The price of an angle grinder will rise in correlation to an increase in size. Smaller hand-held angle grinders typically have motors that range between 1.5 and 5HP.
Disc Size
One of the most important features to look at when buying an angle grinder is the disc size. Smaller models typically take a 4.5-inch disc or occasionally a 5″ disc. Larger angle grinders take a 7 or 9-inch disc. It’s no surprise there are pros and cons to the different sizes.
- Smaller angle grinders are most favored by home hobbyists and the DIY crowd. Models that use a 4.5-inch disc are relatively lightweight and can get into small spaces. Even with their small size, they are powerful enough to tackle most of the projects you have in mind, including grinding, sanding, and sharpening. There is a range of corded and cordless models of this size to meet your needs around your home, yard, or garage.
- Larger angle grinders are more powerful and work well if you do your own auto repair or major remodeling projects. A 7 or 9-inch disc size and increased power are helpful when trying to cut through concrete, steel, or other hard materials. Most of the time, these models are corded to generate more force.
Power Source
As with many of the other power tools you have in your workshop or garage, you basically have two power source choices when choosing an angle grinder: corded and cordless. Pneumatic angle grinders are available for purchase, but the average DIYer doesn’t typically use them as they are mainly used in professional auto body shops.
- Corded angle grinders generate consistent power – typically more than cordless models – due to their reliance on AC from the outlet. They keep you tethered to a physical location and may require the use of a heavy-duty extension cord. The cord can be a nuisance or tripping hazard when working with the tool.
- Cordless angle grinders are helpful when working in tight quarters or areas away from an electrical outlet. On the downside, they aren’t as powerful as corded models, and the power output and speed may wane as the battery drains over prolonged use.
When looking at a cordless angle grinder, keep in mind that you may need to purchase a battery separately. If you’d like to have more than one battery on hand for projects, look for an angle grinder that uses the same battery pack as your other cordless power tools.
Arbor Size
The arbor, also known as a spindle, is the piece you attach the cutting disc or grinding wheel to on an angle grinder. Most angle grinders in the United States have a standard ⅝-11 arbor. This means the spindle has a ⅝” diameter with 11 threads per inch. Some models have a ⅞” spindle, so the arbor size must match the wheel or disc size. Adapters are available to convert a ⅝” arbor to a ⅞” and vice versa.
Speed
Speed is another one of the important grinder features to look at. How fast the disc on an angle grinder spins is measured in RPM or rotations per minute. A higher RPM means a tool can cut through the target material more easily and quickly to get the job done sooner.
- Smaller angle grinders operate at higher speeds than their larger counterparts. They typically operate at speeds in the 5,000 to the 11,000 rpm range. Smaller tools may also come equipped with variable speed controls to tailor the RPM to your project needs.
- Larger angle grinders operate at lower maximum speeds, typically in the range of 5,000- to 8,000 rotations per minute.
The speed listed on the angle grinder is the maximum RPM achievable when the tool isn’t “loaded,” – meaning it doesn’t have a disc and isn’t actively grinding or sanding. Therefore, once in use, the speed will slow down a bit. Keep in mind, too, that the faster a disc spins, the hotter it becomes.
Variable Speed Control
Variable speed control is a handy feature if you plan to use your angle grinder for various tasks. The ability to adjust the speed is beneficial if you are polishing or buffing materials with the tool. Models with a variable speed aren’t as common, and they cost more, but they do give you more control over the RPM and spinning speed when in use.
Dust Protection
Over time dust buildup within the internal parts of an angle grinder can cause the vents to clog, leading to overheating and potentially burning out the motor. This dust buildup can also wear out the gears quicker. This makes dust protection a vital feature, especially when using the angle grinder for long periods.
Some models come equipped with dust protection features such as a seal or a dust ejection system that keeps the dust away from the vents and out of the inner workings of the motor. These features extend the lifespan of the tool, negating the need to replace it soon.
Kickback Brake
A kickback brake is an essential safety feature on an angle grinder, ensuring the wheel is automatically stopped very quickly when a bind-up event, stall, or pinch is sensed. Killing the wheel rotation prevents the tool from coming free and kicking back towards the user, causing severe damage.
Two-Stage Trigger
Some angle grinders come equipped with two-stage triggers, another safety feature that minimizes damage or harm to the user. The separate safety switch must be disengaged with a two-stage trigger before the tool can be set into action. This minimizes the risk of the angle grinder accidentally starting when you are changing the disc.
Soft Start
Due to the fast, powerful motors on angle grinders, they often recoil when they turn on as they are quickly coming up to maximum speed. This recoil may cause the angle grinder to jump in the user’s hands, with the potential to cause serious injury. A soft start on an angle grinder prevents recoil during start-up by reducing the power output initially, ramping up slowly until the grinder comes up to speed fully.
Safety Guard
To protect your hands from the disc when in use, keep debris and sparks from flying towards your face and body, and to protect surfaces in tight spaces from damage, angle grinders come equipped with a safety guard. The safety guard can be moveable or fixed and covers half of the disc, allowing you to see the work area when using an angle grinder.
Moveable guards are more popular as they can be adjusted for right or left-handed use and moved to protect you from flying debris. They can, however, fall off the angle grinder if not correctly tightened.
Fixed safety guards are more robust, providing better protection. They also have no risk of falling off the grinder after being adjusted.
Noise
Unfortunately, angle grinders are loud by nature, and you should always wear appropriate hearing protection when using one. On average, an angle grinder measures approximately 110 dB when operating. Some manufacturers, like DeWalt, have designed innovative gearcases that provide precise gear alignment for smoother, slightly quieter operation.
Thermal Protection
Any motorized tool or piece of equipment benefits from having thermal overload protection, and an angle grinder is no exception. Thermal overload protection, or thermal cut-out, is a safety feature that kills the motor when it reaches a maximum temperature. This prevents overheating and potentially burning out the motor. Once it sufficiently cools, you can turn the tool back on again and continue working.
Conclusion
Angle grinders are incredibly versatile, hand-held power tools capable of performing many different tasks around the home or shop. Slightly larger and more powerful than die grinders, they are fantastic for cutting metal, rebar, stucco, and tile. You can also use an angle grinder for sharpening, sanding, and polishing.
An angle grinder makes a great addition to any tool collection, but it’s essential to understand the different features available to purchase the best angle grinder for your needs.
