Offering the ideal blend of performance and durability, pneumatic angle grinders are ideally suited to cutting and shaping metal workpieces. Pneumatic grinders require connection to suitable air compressor units they are well-suited to high-precision tasks and are considerably lighter in weight than other angle grinder models. The unique disc angle can make straight grinders a better choice than the standard angle grinder in some instances.
Get the most out of your angle grinder by using different types of angle grinder wheels. The most apparent disc and probably the most popular one among different types of angle grinder discs is the grinding disc. Similar to other angle grinder discs, wire wheels are produced in different shapes and sizes because they are used for different purposes.
Of the different types of powered grinders available, the angle grinder is probably the most common and widely used. Angle grinders fitted with the appropriate disc can be used to grind and cut metal or stone. The smaller angle grinders operate at higher speeds – 4½ inch grinder will typically operate at 10000 rpm whereas a large 9 inch grinder will rotate at only 6500 rpm.
Smaller angle grinders usually have a higher RPM than larger angle grinders, which in turn means the small discs get worn out quicker than a large disc would. Perhaps the most common question we receive about angle grinders is what disc should be used for particular jobs. The cutting capabilities of the angle grinder isn’t the only factor you should consider as there are other features which will determine how easy-to-use and comfortable a particular angle grinder will be.
Exactly what you will be cutting should determine what type of cutting disc to choose – cut off discs for metal or stone, diamond disks for slate, marble and abrasive materials, etc. If you only need to cut a 2mm aluminium panel, a 115mm cutting disc is plenty, even if your cutter could mount a 180mm disc. A final consideration is the torque required to drive the cutting disc – many smaller cutters and grinders are physically capable of mounting 150mm or even 180mm discs, but might not be able to supply enough torque to get the cutting disc up to full speed or to maintain that full speed when cutting hard materials.
6 inch grinder size in mm A 6 inch grinder is 150mm. 14 inch grinder size in mm A 14 inch grinder is 356mm. Common Angle Grinder Sizes in Australia Grinders also come in various other sizes, such as a 3 inch 76mm angle grinder, however these are the most common sizes used in Australia.

The shaft the sticks out of the end of the angle grinder at a 90 degree angle is the “Spindle”. Here’s my answer to adapting those smaller spindles as needed:Pete’s Angle Grinder Spindle Adapter Ideas.
how to measure angle grinder disc Related Question:
How are angle grinder discs measured?
Angle Grinder Wheel/Discs The hardness and smoothness of a grinding disc is measured by grit. Just like sandpapers, a lower grit number in a grinding disc means it is coarse and a higher number means the grinding wheel is less coarse.

The size of the disc should have a direct bearing on your choice of angle grinder. The two most common disc sizes are 4.5” (115mm) and 9” (230mm). Grinders with larger discs are particularly well suited to heavy-duty applications, whereas those with smaller discs are ideal for finer work.
How is cutting discs measured?
The Cutting Index can be measured by the following method. Now measure the diameter of the wheel after the cutting and calculate the surface area of the used wheel. Multiply the surface area of the workpieceinto the number of cuts to calculate the total surface area of the cut work piece.
What is the most common angle grinder size?
