1.1. Things to Consider Before Choosing an Angle Grinder

The best angle grinders have some distinguishing features that make them stand out on the market. Here are some important factors mentioned below that you must consider before selecting one.

Power Source

The angle grinders come in both cordless and corded models ie. without and with battery.

  1. Corded grinders have their direct connection with the outlet therefore they can continuously produce more power at a consistent level. But their disadvantage is that they are restricted to a certain location because of the limited range of the cord. It’s also possible that the cables can be a pain to work on and, therefore, possibly inconvenient while working on a project.
  2. Cordless grinders are not as powerful as corded ones. Their functionality majorly depends upon the capacity of their batteries. For instance, if the battery goes down during the project you will be stuck. But the plus point is, you can easily move them to your desired location with no hassle and use them in hard-to-reach areas. 

Size of Disc

The angle grinders are available in a variety of sizes according to their diameters. The tools are denoted by the numbers that represent the exact diameter of the disc they can handle. 4 to 5 inches disc are enough for most home-based tasks. As a matter of fact, the lighter and compact-sized discs are best suitable for DIY projects because it may be difficult for DIYers to handle large and tedious discs.

Most professionals and expert workers however use the angle grinders with larger discs, most probably up to 9 inches. These larger discs have the capability to cut through thick materials. For the large-sized discs, the grinder sizes must also be increased with it. However, it’s not easy to deal with the large and heavier tools as they cause fatigue of hands more easily as compared to the smaller angle grinders.

Voltage

The power output of the angle grinders is measured in amperes and volts. In the cordless angle grinders, the unit of Volt is used to indicate the battery power. However, most of the batteries in cordless models come in 18 and 20 volts, which are highly functional as well as affordable. 

However, the corded angle grinders only show that either they are suitable with 120 or 220 power outlets. The experts can analyze the potential of power output through amperage ranging between 5 amperes to 15 amperes. It is however obvious that the large discs demand large output. Therefore, an angle grinder ranging from 7 to 9 inches disc size requires higher power output. 

Speed

The unit of revolutions per minute (rpm) is used to measure the speed of angle grinders. Normally, the speed of most angle grinders ranges from 5000 to 10000 rpm, however, some heaviest grinders come in the speed range up to 12,000 rpm.

When the rpm (speed) is higher, the more efficiently the target material can be cut. A major drawback is that the disc gets heated up at higher rpm sometimes and is at a high risk of causing injury as it may rupture. Make sure that you are using the right disc for the right task and keep noticing the speed of the disc. It will help you to prevent the grinder from being shattered because of over speed.

Soft Start

The best angle grinders are always powerful and fast tools, therefore, they may recoil sometimes when the power goes high. Larger and robust grinding wheels are most likely to face this issue. As a result of the recoiling in the motor, the angle grinder may start jumping in the hands of the user that may lead to severe damage. 

In order to deal with recoiling, this breakthrough soft-start technology lessens the power output to the motor initially, and then increases it swiftly till the angle grinder is fully in function. This not only prevents the recoiling of the motor but also increases the safety of the users.

Hand Guard

The hand guard on the angle grinders works as a safety measure covering approximately half of the disc. The hand guard prevents the debris and sparks from flying towards the worker and hence protects them from getting any kind of injury. Not only this, but the hand guard also serves as a protector of surfaces while working with the angle grinder in tight areas.

Many angle grinders also come with movable guards while some have fixed hand guards. Most users prefer to pick the angle grinders with movable guards because they are convenient to use for both left and right-handed users. However, a major drawback of movable grinders is that they can fall off the unit if they are not tightened enough.

Handed or right-handed use and can adjust to better protect the user from flying debris. If left untightened, however, a movable guard can fall off the unit. Fixed guards are more robust, and there’s no risk of them coming off a grinder.
