6 Inch Versus 8 Inch Bench Grinder

One is 6 inch bench grinder in diameter and the other is 8.

6 inch versus 8 inch bench grinder.

This dual wheel bench grinder fits wheels with 8 inch diameters and up to 1 inch thickness and comes with 36 and 6 grit wheels. Opting for the 6 inch bench grinder which is a smaller wheel in comparison to the 8 inch provides you with more curvature for grinding purposes. Although 6 bench grinders are arguably more compact 8 bench grinders are unbeatable for sheer power. Simply turn the dial to your preferred speed and start grinding.

Eight inch bench grinders are better suited for professional jobs and heavy duty work. Are there more accessories polishing wheels wire wheels for one size than the other. Going to buy a bench grinder and am looking for advice on whether to get a 6 or 8. Yes the surface speed of a 6 inch wheel running at 3600 rpms is slower than the surface speed of an 8 inch wheel running at the same speed.

Besides the grinder size the other thing you need to decide upon is what type of wheel to go for. For an 8 inch you would definitely want the low speed option. Eight inch grinders are especially suitable for work that requires buffing wheels or wire brushes. Going to be using it for just general use nothing specific.

My 6 inch grinder is variable speed but i run it almost exclusively on its highest setting. In addition to the outright speed of a grinder another reason an 8 needs to be used more carefully than a 6 because for any given speed the surface of an 8 wheel is actually moving much faster so at the same rpm an 8 grinder is more likely to overheat a tool than a smaller one everything else being equal. As you are using a bench grinder you might find that other types of wheels will suit your tasks better. Either 6 inch or 8 inch.

6 inch grinders are great. That measurement refers to the size of the actual grinding wheel and generally speaking an 8 inch s used more by the industrial or professional trades. However your selection of the wheel size has minimal effect on the actual functions. Not only can you choose the size but also the grit as it leaves you the freedom to choose between a 36 grit one or a 60 grit on depending on the type of material you want to work with for work light.
