Best Cordless Angle Grinder Buyer’s Guide

Angle grinders, also called disc grinders or side grinders, can be termed sui generis instruments among handheld power tools. With their splendid capability of operating on metal, they are the best suit for DIYers, plumbers, artisans, and electricians, among other related experts.

They are ideal tools for fabricating tasks about metallic material like grinding, sanding, polishing and cutting metal. However, in an application, these tools are prone to potential safety hazards like:

  • Bursting of the disc.
  • Kickback from binding on an object.
  • Accidental start-ups.
  • Bursting of the guard.

The few listed risks seldom occur, but that does not entirely rule out the chance of occurring. Acquainting yourself with such risks raises the need for an inquisition on factors to look for in a tool to make sure it is ideal for usage. Some of those factors are elucidated below.

Accessory changing methodology

Cordless angle grinders require accessories or attachments for effective and comprehensive performance. These accessories include a guard, a grinding wheel and a cut-off wheel.

The wheel or disc demands you to switch it depending on the application in progress. The guard is of dire essence as it plays a significant role in deflecting debris and sparks emitted when the tool is in operation. It also shields you from the risk of injury if the rapidly spinning wheel slips and goes flying.

It is, therefore, very critical to hold high consideration of the methods a tool has put in place to make accessories changes. Most dominant products improvise a tool-free methodology, which is highly remarkable. Others have spanners on board for a quick and effective accessory switch. A tool with either method should be considered.

User-friendliness

You want a tool that has set well-defined programs to ensure optimum handling and safety of the tool and user. These programs or properties offer critical components for the scrutinization of your appliance of interest.

Examples of such components to tout for include a drop control property that will result in the immediate turning down of the tool if it falls off. This kickback control property lessens the danger that would be posed by the tool unexpectedly jamming on an object.

Another feature contributing to user-friendliness is the soft start property that enables the tool to smoothly start up and gradually gain speed to give room for preparation. Rubberized grips and thin bodies are other features that chip in on user-friendliness by augmenting the handling of the tool for amplified maneuverability.

Battery and motor

All featured implements are cordless, meaning they source their power from batteries. Considering how severe metal fabrication tasks are, the source of power for the tool executing those tasks should correspondingly be monumental.

For that reason, battery power expressed in terms of voltage should be thoroughly considered. Tools backed up with a rechargeable Li-ion battery pack with a voltage ranging between 18V and 20V are considered appropriate. You will find that some brands provide double Li-ion for tool usage. You ought to consider yourself lucky.

You should also check whether the battery cell and charger are included in the purchase package or sold separately. This prepares you financially for extra costs. You should research more in-depth to find out whether your tool of interest is compatible with batteries other than its own because that would be a huge advantage for you.

The motor is the other paramount inbuilt structure in all featured cordless grinders responsible for bringing about a spinning action of the wheel/disc, which is now implemented to execute metal cuts, sharpening, and grinding, among other tasks.

Therefore, the design of this motor structure is pertinent. The structure grants the wheel/disc the spin speed expressed in RPM (rotations per minute). Tools characterized by RPMs ranging between 7,000 and 11,000 rpm are considered reliable.

In conjunction with battery power, the motor is responsible for a tool’s runtime: the time a cordless appliance can run seamlessly per charge. High-ranking grinders have adopted technologies that have served as game-changers by intensively extending the runtime and motor life.

Such motor technologies include Powerstate Brushless motor technology, Bl Brushless technology and EC Brushless motor technology, among others. A tool with such and related motor technologies ought to be highly considered, as it means you will be graced with an incredible runtime to ensure you execute a considerable amount of work.

Conclusion

Cordless angle grinders have become the resort instrument in metal fabrication. They are handy tools for polishing, cutting, sanding and grinding metallic objects. Other units even raisedd the bar and demonstrated practicability on concrete and grooved stone.

The tools have an outstanding detail, such as the side handle that is incorporated in their bodies. In some brands, the side handle is adjustable in two different positions, while in others, it is adjustable in three different positions to increase manoeuvrability. The essence of the side handle is to accord you control over the tool.

You can employ this magnificent tool effectively on home improvement tasks like removing loose paint or grout, tile cutting and eliminating rust, among other home projects. We hope perusal of this article will help you make a guided purchase decision.
