Bench Grinder Buying Guide
Here are the important characteristics of bench grinders to consider when shopping for a new one.
Price/Frequency of Use
Grinders are like most power tools because they come in all different qualities and price ranges. That is why use must consider how well a particular model bench grinder fits into your budget. It is never a bad idea to set yourself a budget range when shopping for a tool like a bench grinder.
Setting a price range to shop in will not only help you stay on budget but it will also narrow down your bench grinder choices so you don’t waste time looking at models you will never buy.
One big thing to consider when setting your budget range is the frequency you will use your bench grinder model. If you will be doing many different tasks with it on a regular basis then it is easy to justify spending a little more on one of these handy power tools. If you won’t be using it a lot there are plenty of budget models available that will do the job nicely.
You really need to also consider how powerful you want your bench grinder to be. Some grinding tasks require the grinding wheels to spin at very high RPM’s. So this is something to seriously consider if you will be shaping metals or doing some serious grinding down of metals on a regular basis. The higher the RPM’s a bench grinder has the better it will be at doing the heavier duty grinding tasks that you require.
If used improperly a bench grinder has the potential to cause serious injuries. Most manufacturers go to great lengths to add safety devices to their grinders that will greatly reduce the risk of injury when using them.
Here is some of the built in safety devices that should be standard equipment on any model bench grinder that you are considering buying:
There is no way you can grind any type of metal in a way that it won’t create sparks. Since sparks are basically super-heated small chunks of metal they are not something that you want flying all over the place. That is why a good properly installed spark deflector is an essential piece of safety equipment.
These are usually small pieces of flat metal that are installed closed to the top portion of the exposed grinding wheel. As you grind the centripetal force created by the grinding wheel tends to pull the sparks all the way around it as it moves. The spark deflector angles the sparks that hit it in a downward fashion so they do not go back toward the tools user.
Out of safety concerns over the year’s bench grinder manufacturers have come up with ways to make using bench grinders much safer. One of the most innovative pieces of safety equipment that is almost standard equipment now on most model grinders is a plastic eye shield. These are located at the top portion of a bench grinder and placed in a way that metal fragments from grinding will have a hard to shooting upward toward a user’s face.
**** Important to note: Eye shields should not make you confident enough to use any bench grinder without wearing proper eye protection. When using any type of power tool protective eyewear must be worn no matter what safety measures a company builds into its power tools****
Wheel guards are pieces of heavy plastic or metal that covers the exposed bottom of a grinding wheel. These are put in place so you don’t accidentally catch your clothing and have you pulled toward the speeding grinding wheel and to keep your body parts from accidentally coming into contact with the rotating abrasive grinding wheel as you are using it.
Here is a photo that clearly shows all these different safety features in place:
Grinding wheel options
Most bench grinders come with both a coarse and fine grinding wheel. There are other types of grinding wheels such as ones that are made of steel brishes for cleaning and polishing. A model bench grinder that makes it easy to change out grinding wheels can be very convenient to own.
You also have different size grinding wheels that bench grinder products come with. Keep in mind that you can’t interchange wheel sizes on a bench grinder model so be wary of that when making your selection. Bench grinders generally come with 6, 8 or 10 inch grinding wheels. Smaller grinding wheels are better for precision grinding tasks and polishing. Large grinding wheels are best for heavy duty grinding tasks.
Adjustable Tool Rest
Your hands tend to get pretty tired if you have a lot of grinding to do. That is where an adjustable tool rest comes in very handy. They will really help to cut down on arm and hand fatigue as you are working.
Here is a close up shot of an adjustable tool rest:
You want your grinder to last you for a long time so there are certain construction characteristics of bench grinders that will help you achieve that. Look for things when shopping for one such as a cast iron base, metal alloy motor casings
Get as long and as inclusive a warranty as you can get with your bench grinder purchase. This is especially true if you spend the money on a more expensive model. A good warranty is a nice peace of mind to have with any power tool purchase.
