What To Look For In An Angle Grinder?

1.  Disc Diameter

The disc diameter is an important factor for an angle grinder. Angle grinders with bigger disc diameters are more powerful. The larger the disc, the greater the cutting depth of the grinder.









2.  Power Source

You can get an angle grinder with 240v or 110v. There are also smaller grinders that are rated for 18v. Angle grinders measure power output in volts (V) and amperes (Amps).









3.  Speed

Another important factor to consider when choosing an angle grinder is whether it features variable or single speed. You will have the ability to perform more delicate work at lower speeds with variable speed angle grinders than with single speed grinders. However, variable speed angle grinders are more expensive than single-speed grinders. The speed is measured in revolutions per minute and the higher the RPM, the easier and more quickly it cuts through the material.









4.  Brushless Grinders

Another factor to consider when choosing an angle grinder is whether it has brushless motors. They are more powerful with fewer parts to wear out. Brushless grinders eliminate the need for brush changes and they run more efficiently.










5.  Safety Features

Another important factor to consider is safety. There are a number of safety features that protect and prolong the life of the grinder. Some Angle grinders have the slow start feature. This allows the motor to slowly increase speed until it reaches full capacity thereby preventing it from twisting immediately on start-up.

An anti-kickback function allows the grinder to cut out if the wheel gets bound up. Another safety feature of angle grinders is the restart protection that prevents the grinder from starting up again if it is overheated or has cut out and been left on.

Another safety mechanism designed to ensure the grinder is held by two hands and is used to stop the grinder spinning if the switch is released is called a paddle switch or a Deadman’s Switch.










6.  Vibration Control

Vibration control is an important factor to consider when you choose an angle grinder. It prevents your hand from going numb and helps to keep it comfortable.









7.  Dust Protection

Dust protection is not one of the most important factors to consider but it is important to the life span of the grinder. Some angle grinders are designed with dust protection like a dust seal or dust ejection system to keep out dust and debris from entering the grinder.









8.  Hand Guard

The handguard protects your hand by keeping out sparks and debris from hitting you and also protects surfaces from damage. Some of the handguards are moveable while others are fixed.










9.  Spindle Lock

The spindle lock mechanism allows for quick accessory removal and replacement by preventing the wheel from rotating. However, there is a metal nut that is designed to prevent the risk of the system locking while the grinder is running.













Types Of Angle Grinders

1.  Corded Angle Grinders

Corded angle grinders get power from the main outlet and provide more power which is not limited. They are inexpensive and lighter than cordless grinders. However, it limits your mobility as you must be located where the main outlet is situated.









2.  Cordless Angle Grinders

Cordless angle grinders give you mobility as you can take it wherever you need to work. They are powered by batteries and with the advancement in technology, cordless angle grinders can last for quite a while before you will need to recharge it or replace the battery.









3.  Pneumatic Angle Grinders

Pneumatic angle grinders are powered by air pressure. They have to be plugged into an air compressor to work. With no need for batteries or electric motors, pneumatic angle grinders are the lightest angle grinders.







Types Of Grinders

1.  Angle Grinders

Angle grinders’ gear heads and the attached disc make a 90 degree when it is held in your hand. Thus they are called angle grinders to differentiate them from the straight grinder.







2.  Straight Grinders

Straight grinders have the wheel at a 90-degree angle and this makes it useful for grinding the outer edges and inner parts of pieces when a different grinding stone is attached.







3.  Die Grinders

Die grinders work similar to the straight grinder, but instead of abrasive discs, they take dies that work like drill bits in action. Die grinders are designed for shaping and polishing round objects such as metal pipes and plumbing. They can also be used for fabrication, engraving, contouring, and woodworking.








4.  Wet Grinders

Wet grinders polish and grindstone and tile. To get a smooth finish, wet grinders use an abrasive disc with fine grit. Water is used to cool and lubricate the cutting wheel to prevent cracking or damaging the stone or tile.









5.  Bench Grinders

Bench grinders are stationary machines that are bolted to a work table or bench. They are used for heavy-duty cleaning, grinding, sharpening tools, shaping, and buffing of metal, stone, pipes, and wood.








6.  Belt Grinders

Belt grinders are used for finishing processes including finishing surfaces, deburring, and stock removal. Belt grinders are used on metals and other tempered materials.








7.  Floor Grinders

Floor grinders are used for large commercial, civic, or residential applications with a large floor square footage that requires grinding. They are used to level, smooth, or clean concrete surfaces with horizontal rotating discs that remove surface material.








8.  Electric Grinders

Electric grinders are powered by electricity and have to be plugged into a power outlet. Electric grinders limit your mobility as are restricted to how far the electrical cord reaches.









9.  Cordless Grinders

Cordless grinders are portable as they are powered by a battery. They make you mobile but are not as powerful as the electric ones.









10.  Pneumatic Grinders

Pneumatic grinders use air pressure for their power. They don’t need motors or electric cords but they need an air compressor.










Angle Grinder Accessories

1.  Wood Carving Disc

This wood carving disc is used for polishing, grinding, and cutting non-metal materials & all kinds of wood.








2.  Grinding Wheel

The grinding wheel grinds and shapes a variety of metals and non-ferrous materials.


How powerful should an angle grinder be?
To polish, the angle grinder needs 500 watts, It will need to have 1,000 watts of power for grinding. For cutting through simple materials, it will need 1,500 watts and for cutting through strong metals it requires 2,500 watts of power.
Is a brushless angle grinder better?
A brushless motor makes the grinder more durable and powerful than corded angle grinders.
What should I look for when buying an angle grinder?
When choosing an angle grinder, there are some features you need to focus on such as the speed, disc diameter, power source,<br /> vibration control, etc.
