best bench grinder

Many people associate bench grinders with professional workshops, but these incredibly useful power tools can be an affordable addition to your own DIY kit. A bench grinder is a useful tool for smoothing out wood and metal surfaces, but can also be used for sanding applications. They can also be used to sharpen the edges of tools, allowing you to keep your DIY essentials in optimal condition with minimal effort. Need some further guidance on what to look for when selecting the best bench grinder? Read on for our bench grinder buying guide.

Bench Grinders Explained

A bench grinder is a heavy-duty power tool that includes two wheels that spin at high speeds. Usually, bench grinders feature two varieties of wheels to provide you fulfil different applications. In most cases, one wheel is coarser in texture, while the other is finer. Faster bench grinders can be used to make cuts in wooden work pieces, or even some metal sheeting. Bench grinders with slower rotational speeds are handy for buffing wooden surfaces or polishing other pieces down to a smooth finish.

Bench grinders can also be put to use if you need to sharpen up your tool collection. More or less any metal tool with an edge can be sharpened with a bench grinder wheel. If you are a DIY enthusiast with a lot of tools in their collection, a bench grinder can be a worthy investment just for this application alone.

Bench Grinder Dimensions

If you are looking for a bench grinder to use at home in your own workshop, you will probably be limited to smaller models. The smaller the bench grinder, the smaller the motor and the less powerful it will tend to be. However, even the smallest bench grinder should be powerful enough to carry out a variety of cutting, grinding and sanding tasks. You can also use them for polishing and finishing jobs if you select suitable wheel attachments.

Although compact bench grinders have their limitations, they can be very effective for carrying out delicate work requiring precise control.If you can afford to purchase a larger bench grinder and have the space to house it, you can expect to carry out more substantial cutting and sawing. You can also undertake more heavy-duty filing tasks with a larger bench grinder.

Motors

Even if you are limited to a smaller bench grinder, you can still enjoy high levels of performance if you purchase one with a powerful enough motor. The higher the motor rating, the more efficient it will be. A more efficient motor makes it easier to cut through masonry and hardened materials like metal. If possible, choose a bench grinder with a brushless motor. This type of motor is generally more efficient, but also has the benefit of requiring no maintenance or brush replacements.

Rotational Speed

The speed of your bench grinder will also determine how effective it will be at carrying out cutting, sanding and grinding tasks. If you plan on working with hardened materials, you should look for a bench grinder that delivers very high speeds of around 2000-3000 RPM. However, if you only intend to work with wood, a lower speed should be more than suitable for your needs.

Grinding Wheels

A hallmark of any bench grinder are the grinding wheels on either side of the main unit. First, you will want to think about grinding wheel size. Most compact bench grinders allow you to use grinding wheels with a 6-inch diameter. These are fairly versatile and fine for most tasks, but they will eventually wear out and require replacing.

You also need to consider the grit of grinding wheels. As with sandpaper, there are various grit sizes to choose when selecting a grinding wheel. Bench grinders usually come with two different grits supplied, with a smoother grit and much coarser grit provided. You can of course change wheel grits to meet your individual needs.

Essential Safety Features

As a bench grinder works at speed and at high power, you can not overlook the importance of safety. Spark deflectors should be standard with any bench grinder. These guards cover a substantial part of the wheel diameter, leaving only a small section of the wheel exposed. This prevents sparks from flying into your eyeline as you work. Additional eye shield may also be included to add a further barrier between you and your workpiece.

If you want to use your bench grinder regularly in poorly ventilated indoor spaces a dust extraction system is also advantageous. These dust removal systems will ensure sawdust and other debris is quickly removed from your work area, preventing you from breathing them in or getting debris stuck in your eyes. Finally, you may wish to purchase a bench grinder that includes an adjustable work light. These lights are both convenient in that they illuminate your grinding wheel and materials as you work so you can achieve precise results, but also make it less likely that you accidentally make contact with wheel as you handle materials.

Bench Grinder Buying Checklist

If you want to take your home workshop to the next level, a bench grinder is something you should probably invest in. When choosing a bench grinder, first thing about the amount of space you have available for it. If you have a larger area to play with, go for a bigger bench grinder as these will usually include a more powerful motor. However, even compact bench grinders can include powerful motors. Go for the most powerful motor possible, unless you only intend to use your bench grinder for very delicate work. If this is the case, a more modest motor with a slower rotational speed may be a better fit.

Grinding wheels also warrant some further thought. If you are sticking with a smaller bench grinder, you will probably find yourself limited to a 6-inch wheel diameter. Regardless of the size of grinding wheels you will be working with, make sure you have a bench grinder that allows for easy removal and replacements of wheels. Grit sizes are also important. Most bench grinders will come with two different grit sizes supplied, giving you a choice of coarse and fine grit textures.

Finally, make sure your bench grinder does not neglect safety. The minimum safety features you need include spark deflectors and eye shields, although dust extraction systems and cooling systems are also good to have. An adjustable work light is also a very useful feature addition, although models that include them can be far more costly than basic bench grinder products.
