Product Information

You do have to choose the right wheels for this grinder, as it can wobble a bit with cheaper wheels. But get some good quality wheels on it, and the performance is stable and reliable. Grits also come in different colors, which indicate the type of material used. Like grit sizes, different colors are better suited for different purposes. Lower bench grinding speeds help keep heat build-up under control - If available, use a lower bench grinding speed to keep the heat build-up, on both the object being ground and the grinding wheel itself, under better control. The best bench grinder for the workshop or garage runs at a consistent operational speed and delivers with minimal vibration. You will definitely get more use out of an 8” grinder and a variety of wheels than you would with a 6” grinder and the same set of wheels. Choosing the best bench grinders

An integrated light isn’t essential, but it does come in handy for working in low-light conditions. Even if your workshop is brightly lit, having a light on your bench grinder will let you see the workpiece more easily.Bench grinders are fairly simple in terms of design and function, so even a DIY brand should provide satisfactory performance for a tool that’s not used often. Make sure that the wheel has access to a reasonably wide area of your workpiece. You may have to remove the guard that normally provides protection when grinding, but be aware that the guards on some models are part of the main casing and are usually unremovable. Use the appropriate grindstone grits for the job at hand - Coarser grit wheels will remove material faster leaving less time for the tool or the wheel to heat up. Therefore, use harsher wheels when a lot of material needs to be removed. In contrast, finer wheels are used for removing smaller amounts of material, such as when finishing off a blade edge. However, if the blade is chipped or is overly dull and more material needs to be removed to reform a uniform blade edge, a coarser wheel may be needed initially. If you do need the more acute curvature provided by a smaller wheel, you can simply swap out the standard 8” wheel for others that are better suited for the job you need to do.

One notably nice feature about the Makita bench grinder is that the housing over each wheel contains an integrated light that lights up the grinding area. However, it should be noted that these lights only come on when the machine is in operation whereas ideally we would have liked to see them have a separate control switch so that they could remain permanently on if desired. Remember if a bench grinder is a brush-type motor you could use a rheostat or a dimmer circuit to control the speed on a pro-brand tool. Should you get a 6 or 8-inch table grinder? Do not use a bench grinder to grind aluminium - Bench grinders are designed for grinding down steel and similar metals. However, never use a bench grinder to grind down aluminium as the filings generated from this metal can accumulate in the wheel, which then can ignite when the wheel becomes hot during a later grinding session. This can cause the wheel to disintegrate as it is being used, with the resulting danger to the user.

You can generally avoid this by using a rough grit wheel and slow rotation speeds, although this isn’t always practical. Buffing is pretty easy once you know how, although you will first have to become familiar with how different surfaces react to the buffing wheel. The Dewalt or a Jet bench grinder are popular choices, depending on if you want the best or the best value. So what size to get? After deciding on whether the bench grinder size will fit in the workshop space allocated for it, choosing which size is best is to some extent a matter of personal preference. The size of the wheel does affect some characteristics of the bench grinder, like a larger wheel has a faster angular velocity at the grinding edge affecting the rate of frictional heating, or smaller wheels are more curved at the grinding point which can cause slight differences in bevel formation, however, for the most part, the effect on actual function is minor. Power As with all power tools, getting the most out of your bench grinder involves knowing what you will use it for and what the best features and accessories are for the job.
