Angle grinder purchase instructions

 

Disc diameter - larger diameter angle grinders produce larger discs that make deeper cuts

Wattage - higher wattage gives more power to cut through denser materials

Speed ​​- multi-speed gives more control for precise work

Brushless - angle grinders with brushless motors tend to last longer, have more power and run longer.

Power source - 110v modules are a requirement for work sites, 240v appliances are designed for home use, and cordless grinders allow great movement no matter where it is located.

Safety Features - Slow start, anti-kickback grinding and paddle suids help prevent injury.

 

Main uses for angle grinders

There are four main uses for angle grinders;

 

Cutting: Square grinders can be used to make cuts in metal, ceramic and masonry. They are often used as an alternative to sauces for cutting purposes, due to their movement. Square grinders are great for cutting material ‘in-situ’ (where it was originally), which saves the hassle of moving the material to the cutting machine.

Grinding: As the name of an angle grinder suggests, ‘grinding’ materials are the main use for the machine. An angle grinder can help move and remove excess material, quickly and easily. An angle grinder can grind masonry or excess metal from welding.

Polishing: Square grinders are also used for polishing surfaces using special polishing discs or mop attachments. The high RPM of angle grinders makes them a great tool for creating narrow finishes on materials.

Sanding: While a traditional sander is the best tool to use for sanding, a grinder can also be used with sanding discs. Using a sanding disc, the angle grinder can smooth metal surfaces and masonry.

 

Key Considerations When Buying an Angle Grinder

Here are some key tips to look out for when buying a corner grinder:

 

Disc diameter: disc diameter is a major choice to make when choosing an angle grinder. The larger the disc, the greater the cutting depth of the tool. Square grinders with a disc diameter are usually more powerful.

 

Our angle grinders have disc diameters with sizes ranging from 4 "(100mm) to 9" (230mm), with the 4.1 / 2 "(115mm) & 9" (230mm) grinders being the most popular choices. Smaller grinders rotate the discs at higher speeds and are easier to handle. The downside of smaller grinders, however, is that they cannot cut as deep as larger angle grinders, and their discs need to be replaced more frequently as the wear rate is higher.

 

Wattage: higher wattage provides more power for cutting through tough materials such as thick steel. If the grinder is to be used for a long time, a higher wattage is also recommended.

 

Speed: single speed and variable speed grinders are available. Variable speed angle grinders allow more delicate work at lower speeds, but usually increase the price of the machine.

 

Brushless grinders: brushless motors are more powerful and have fewer parts to wear out, so they are well worth the extra cost in a challenging environment. Grinders are available in 240v and 110v mains (for site work) and smaller grinders are now available in 18v amorphous wire. Recently, some 36v and 54v cordless angle grinders have been launched which offer similar performance to larger mains power tools.

 

Safety features: Some larger angle grinders come with a slow start, where the motor accelerates slowly at full speed, preventing it from turning immediately when starting. An anti-kickback action on an angle grinder causes it to cut out if the wheel is attached. Restart protection prevents the grinder from restarting if it is too hot or has been cut out and left on.

 

Some grinders are equipped with a paddle grinder, sometimes called Deadman’s Switch, which is a safety device designed to ensure that the grinder is held by both hands, and it is ai
