Our Best Choice recommendation if you are on the hunt for an 8 inch Bench Grinder is Dewalt DW758.

With its cast iron base this is a heavy duty bench grinder that won’t let you down, and we have to say, given the great consumer reviews it receives, that the Dewalt is suitable for a whole range of versatile grinding operations.

It’s not all about having the fastest power tools in the shed as our next slow speed bench grinder demonstrates. The Rikon Professional is another 8-inch grinder but rather than operating at a variable speed, or delivering a high RPM like the Dewalt unit we just reviewed, this Rikon operates at 1750 RPM. In this case, though, that’s very much a good thing as it means it can do heavy lift (and by that what we really mean is metal grinding) jobs without the fear of the unit overheating. It still has a powerful 1/2HP motor which means that it’s more than adequate for successfully tackling shaping as well as sharpening jobs in your workshop. There are dual dust collection points as well as adjustable safety spark shields plus a flexible LED light. All that and the Rikon bench grinding machine has a solid cast iron base with rubber feet that both minimize vibrations and hold the unit more securely in place on your worktop.

Bench Grinder Buying Guide & FAQ
Bench grinders are certainly a popular power tool and are favorite for completing a range of diverse jobs including polishing, grinding, and belt sanding and they come with a variety of different capabilities, feature, and benefits to choose from. We’ve picked out some of our key recommendations below of the aspects we suggest you consider before investing in a new bench grinder for your workshop.
Features To Look For In Bench Grinders
Motor Power-Power is, of course, essential and is denoted by the amount of Watts a machine has. The more power it has, the better and more efficient it will be at tackling more robust materials. If you also want to be able to polish and not just grind with your machine, then the more power, the better.
Speed-The speed at which your wheel rotates will determine how long it will take to sharpen and buff those tools. The higher the RPM, the faster the wheel will turn but also the more likely it is to heat up too. The average professional-grade grinder will go up to 3500 RPM with slower machines starting from 1725 RPM.
Safety Features-The key to using a bench grinder is to ensure that you do it safely and exercise the necessary precautions. There will be all kinds of debris, not to mention sparks flying around, so it’s always advisable that you opt for a bench grinder that features safety eye shields as well as protective spark guards too to protect your vision.
Anti-Vibration Features & Noise-The more powerful a machine is, the more likely it is going to be to produce noise and also to vibrate, both of which can be annoying if not disruptive. The more solid and robustly constructed your bench grinder is, especially if it features a sturdy and heavy base, the less likely it is to move and make lots of noise. On the whole though, as popular power tools go, bench grinders are among the quieter ones.
Built-in Lighting-A great additional feature as it will help to illuminate the area that you are working on and ensure that you achieve more accurate results.
Grinding Wheel diameter & Size-Before we discuss the types of wheels available, let’s quickly consider the wheel diameter required too. The larger the wheel, the larger the size of the unit itself will be and therefore the more prominent it’s footprint and workbench space required. The most common dimensions for grinding wheels are:
- 75 mm (3 inches)
- 150 mm (6 inches)
- 200 mm (8 inches)
Besides the obvious question of the physical space that you have available to house your bench grinder which will in part determine which of the above you opt to purchase, the other things to consider are the frictional heating and velocity. Functionality wise there isn’t much difference between the three, so it’s also a matter of personal preference.
Types Of Wheels:
Selecting the most appropriate grinder wheel for your needs is an important consideration, and the decision will mostly come down to the kinds of materials you intend using your grinder with. There are three main types that you could opt for; straight, cylinder and tapered.
Straight Wheel-These are popular and very commonly found across most of the professional brands. They come in various sizes and are typically used for sharpening chisels and other essential handyman tools.
Cylinder Wheel-Larger in size than the straight week, the cylinder wheel also has more limitations as it can only be practically used with vertical or horizontal style bench grinders.
Tapered Wheel-As you can probably guess from the name, this type of wheel tapers off in design towards the edges which makes it an excellent choice for when you are dealing with more dedicate DIY projects.
Safety Tips: Bench Grinder
Below we’ve listed out some of our top safety tips when using a bench grinder.
- Always wear the correct eye protection such as safety glasses, side shields or even a full face shield to protect from high velocity flying debris
- Don’t wear loose fitting clothing that could become trapped in the machine
- Ensure that you have the correct grinding wheel for the job and that it’s securely in place before you start
- Check that all the safety guards are in place before you start
- Adjust the tool rest to within 1/8 inch
- Routinely inspect your wheels for any cracks
- Never use a cracked wheel
- Stand to one side when you first start up your grinding machine
- Ensure that the RPM of the grinding wheel and the grinder are verified and matched
- Allow your grinder to get up to its regular operating speed before you commence any work
- Maintain good housekeeping and keep your work area clear and clean
- Don’t operate your grinder in an area where there are flammable materials
- Turn off your grinder when not in use and allow it to come to complete standstill
