Angle grinders are handheld power tools that, depending on the blade or attachment used, can grind, buff, polish, cut, sharpen, and clean. Corded angle grinders require you to remain within reach of an electrical outlet, but in return, you gain more power and no fears of running out of power before you finish your task. These angle grinders aren’t exceptionally heavy and are small enough-most are around 12 inches long-to get into small spaces, and yet large enough to have the power to tackle most typical grinding, sanding, or sharpening tasks around the home, yard, or garage.
Corded angle grinders are the type you need to plug continuously into a power source before working. Large angle grinders usually come with a slower pace of about 6,000 RPM, while the medium angle grinders come with a faster than 8,000. Without any further ado, let’s hook you up with the best angle grinders out there!

best rpm for angle grinder Related Question:
Is higher rpm better for angle grinder?
Boyd said, “Working at the highest RPM, even if it is a variable speed machine, may give you the fastest removal rate for grinding. But depending on the tool or abrasive, the abrasive could wear more quickly, and you might not get the overall productivity.
What is good rpm for a grinder?
The speed should be between 850 and 1,600 RPM. If you are cutting stainless steel and tool steel, with a 4-inch disc, the speed should be between 3,500 and 6,000 RPM. If you are using a 7-inch disc, the speed should be between 1,900 and 3,200 RPM.
What rpm does an angle grinder spin at?
Unlike drill motors that run at about 700 to 1,200 rpm, grinders spin at a breakneck speed of 10,000 to 11,000 rpm. They’re fast enough to be scary!
Is a variable speed angle grinder necessary?
Variable speed will be used if you want to use the angle grinder as a polisher/buffer, as those wheels wont work as well at 10,000rpm.
Do I need a slow speed grinder?
Consider a Low-Speed Grinder for Sharpening If you’re careful and keep the wheel dressed (more on that in another tip), these high-speed grinders work fine. But for sharpening, a low-speed grinder running at 1,750 rpm is a better choice. The lower speed reduces the chance you’ll overheat the edge of your tool.
How is RPM calculated on a grinding wheel?
If you want to maintain exactly the same chip load, the equation is: new rpm = original rpm × (original diameter ÷ current diameter)1.5. So, if you were running your new 18″ wheel at 1,800 rpm, run it at 2,366 rpm [1,800 × (18 ÷ 15)1.5] once it gets down to 15″—again, within the safe speed.
What is machine RPM?
Rpm is the speed of rotation of a machine expressed in revolutions per minute. The drum rotates at a speed between 400 and 700 rpm. If the speed is 4000 rpm, the induction motor will act as an asynchronous generator. Rpm is the speed of rotation of a machine expressed in revolutions per minute.
How deep can a 125mm angle grinder cut?
All in all, 125mm angle grinders are extremely versatile tools despite their limited cutting depth of just 38 mm. While 115mm angle grinders offer a maximum cutting depth of only 30 mm, they are precise, easy to handle and lighter than larger versions.
What is the most common angle grinder size?
The most commonly used sizes are the 4” and 4 ½”. These grinders typically have the capacity for wheel diameters of up to 7”, with particularly small versions having the capacity for 3” discs.
Is the DeWALT grinder variable speed?
The DeWALT DCG412M2 125mm XR Premium Angle Grinder has a powerful fan cooled motor and intelligent variable speed trigger.
What does no load speed mean on an angle grinder?
The speed of an angle grinder determines the quality of the cutting or grinding action. This is measured by no-load speeds, which means ‘how fast the disc will rotate before it makes contact with the work piece’.
What is the speed of grinder?
Grinding wheel speeds should be maintalned with-in a range of 5000 to 6500 feet per minute (1525 to 1980 meters per mm), unless special conditions prevall or equipment and wheels designed for substantially higher wheel speeds are used.
What RPM is a slow speed grinder?
Slow speed grinders are kinder and more forgiving to the workpiece. Tools of this sort operate at speeds of 1800 RPM, or even slower. These relatively slow RPMs generate heat too, but it happens at a more controllable pace that is ideal for work on delicate metals.
Will a router speed control work on a bench grinder?
Router motors and most bench grinder motors are significantly different. The commercially available speed control for routers will not AFAIK work on a bench grinder.
What is a slow speed grinder used for?
Slow speed bench grinders are excellent tools for sharpening, cleaning, polishing, and shaping metal.
