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. A medium-sized angle grinder is expected to go faster than 8,000 RPM, while a larger angle grinder may generate around 6,000 RPM. However, the larger angle grinder will have far more power.
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.
We’ll decide what’s the right angle grinder size for you: we’ll go through a series of common activities and determine which is the right size for them. To get an idea of the specs of this size of angle grinders, let’s take as an example the Makita GA4030K 4″ Angle Grinder. If you need to cut through paving slabs, you need to consider a couple of things before choosing the correct angle grinder size for the job.
Blacksmithing Contact Us. Here’s a basic question that I received recently:Debbie asks:I am new to angle grinders. The shaft the sticks out of the end of the angle grinder at a 90 degree angle is the “Spindle”. The problem for us users is when we see a disk whose grit or style is what we want, but the disk doesn’t fit our angle grinder’s spindle. So we need to be know what size our angle grinder’s spindle really is when selecting a disk. “I found this general explanation about spindles on the”net” just now:————————————————–“The “Standard” spindle thread these days on a angle grinder in the US is 5/8-11. While the above article is generally true, the author fails to recognize that we in the USA import LOTS of angle grinders and they often DO have those smaller diameter spindles AND with metric threads. Here’s my answer to adapting those smaller spindles as needed:Pete’s Angle Grinder Spindle Adapter Ideas.
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.
We will discuss a few tips for choosing the right grinder size for the job. If a 7-inch grinder is spinning at speeds of 5,000 RPM while it is sanding a floor, its greater design and slower speed is generating less heat than a 4.5-inch grinder that is spinning away at 10,000 RPM. While the greater speed gives the grinder more power, it also makes it much easier to fail. These are just a few tips for selecting the right grinder size for the job.

What is an angle grinder arbor?
The angle grinder arbor, which is commonly knowns as spindle, is the shaft that protrudes at a perpendicular angle to the grinder’s end. This is the component to which the grinding/cutting wheel is attached. It is powered by the grinder’s drive motor and threaded at the outboard end.
Are grinders true to size?
