Things to consider before buying angle grinders in India.

Disc Size

The most popular choice is 4.5 inches or 9 inches when it comes to the disc size of angle grinders. Normally if the size if the disc is bigger then the power of the motor is also more. Sometimes you may need a pneumatic angle grinder to make that precise cut since it has smaller and faster cutting disc.

Motor Power

Angle grinders come in different shapes and sizes to fit everyone’s need. You may have an option to choose between 110 and 230 volts AC (Voltage), 500 to 2500 watts and you will also have to check the amp ratings which normally range from 4 to 15, these numbers are directly related to the power of the angle grinders for any job.

Voltage, wattage and amp ratings can vary in angle grinders. With regard to current, tool buyers have a choice between 110 and 230 volts AC, and amongst wattage ranges from 500 to 2,500 watts. Another consideration is the unit’s amp rating; ranging from 4 to 15, these numbers directly correlate to the power of the motor. Although a lower rating is sufficient for household tasks, heavy-duty professional projects call for an angle grinder with more amps.

Speed Ratings

The power contained in a hand-held angle grinder is incredible. During operation, the unit’s disc makes anywhere between 5,000 and 10,000 revolutions per minute. While this means the hard-working power tool optimally performs any number of grinding, sanding, or cutting tasks, it also translates into a high risk of injury if the powerful grinder is not handled properly.


Two things that directly affect the comfort of using a tool are its size and weight. With angle grinders, the two go hand in hand. Unless a buyer intends to use the power tool for large construction or industrial jobs, perhaps a smaller unit would be more comfortable. Not only are more compact units easier to hold for long periods of time, but angle grinders with anti-vibration handles take operational comfort even further.

Wheels and Accessories

Angle grinders are remarkably versatile tools. Not only can their discs be interchanged, but users can install different wheels and accessories, as desired. With the wide variety of wheel and brush attachment styles available, the handyman should read packaging and usage guides to ensure purchasing the right tool for their job.
