best bench grinders review

If you’re still looking for the best bench grinders online with no success, your luck is about to change. At this website, we have gathered the best bench grinder reviews so you don’t have to venture far to find what you need. A bench grinder is basically a motor with spindles on both ends. However, the features and functionality depend on the brand. That’s why I have prepared this guide. We have narrowed the choice down to the top 5. I also include here a buyers’ guide and general information about bench grinders. But first let us go over the benefits.

Why need a Bench Grinder

Carpentry: The best bench grinders are essential for home projects like renovating your bedroom, cabinet building or deck construction. You can use bench grinders to smooth rough areas and level joints. Bench grinders are ideal for wood furniture construction, bevels and grooves.

Flooring: Grinders are ideal for raising nail heads and leveling buckle joints. You can also use it to remove excess grout or tile. Whether it’s tile or wood, these grinders can simplify your work.

Painting: With a grinder you’ll be able to prepare any surface for painting. A grinder levels any swell and gets rid of old paint. Even paint that is years old can be removed by a grinder. Its function is similar to sandpaper, only more efficient.

Plumbing: You can use a bench grinder for cutting worn out pipes. You can also use it to make way for new pipes. If the cut doesn’t turn out as smooth as you like, use the grinder to flatten it. You can also use a bench grinder to slice through the wall and flooring. With this tool you or the plumber will be able to gain access to the piping and tubes.

Advantages of the Bench Grinder

  • As the best bench grinder reviews point out, these tools are primarily for sharpening. If you’ve got an object you want to sharpen, this will do.
  • Bench grinders can also be used for honing and shaping.
  • These tools are often used to get rid of burrs in castings. It is also the tool you’ll want to use to dress rugged steel. In general a bench grinder works well for all around metal shaping.
  • You can add different wheels on a bench grinder. Depending on the wheel you can use the tool to clean, polish, sharpen or shape any metal.

Types of Bench Grinder

There are two types of bench grinder—6-Inch (Regular Speed) and 8-Inch (Slow Speed).

6 Inch Bench Grinders

The 6 inch grinders move at standard speeds. These have enough power to handle most home improvement tasks. Most of them run at 4 amps or in that range. RPM level is around 3400 to 3600. They are quiet, though some are heavy.

8 Inch Bench Grinders

8 inch bench grinders are for professionals. The 6 inch works fine for most people. But if you’re doing extensive work, use a buffing wheel or wire brush, an 8 inch is better. 8 inch bench grinders are slower but need fewer wheel changes.

Things To Consider Before Buying a Bench Grinder

The best bench grinders are not necessarily the most expensive. Rather they’re the ones that satisfy your requirements. Here are some guidelines and suggestions you may follow:

  1. Decide what you will use the tool for. In the section above, you have to choose between a 6 inch and 8 inch model.
  2. Look for a durable model if you’re going to use it for sharpening metals and rusted objects. Some bench grinders have specialised uses so read the product description.
  3. The wheel is the most vital component of the grinder. Make certain the bench grinder works with the wheel you have in mind. Fine grit grinding wheels, wire brush wheels, buffing and coarse grinding wheels are the most common.
  4. Motor power is also important. The larger the motor the stronger the grinding power. If you’re going to work with large metals, buy a bench grinder with the most powerful motor you can afford.
  5. Think of the long term. If you’re only going to use the grinder occasionally and for light work, get a standard bench grinder. If you’re a professional or see yourself doing more complex grinding, get a more powerful tool.

How to Use a Bench Grinder

  • Turn on your bench grinder. Wait until the tool attains maximum speed.
  • Stand in front of the bench grinder.
  • Hold the metal. After putting it on a tool rest, push in the direction of the bench grinder.
  • Stop when it reaches the edge. Don’t let the metal make contact with the grinder’s sides.
  • To grind a metal, move the piece back and forth until the desired metal part disappears. Don’t hold the piece too long in one place because it could overheat and get damaged.
  • To cut a metal: grab the metal. Rotate it until the bench grinder touches the part you want cut. Keep turning until the desired piece is broken off.
  • To shape a metal: set the part of the metal you want shaped against the bench grinder. With a back and forth movement, grind until you get the desired shape.When the metal turns orange, pull the metal away. Bend the metal with your hands into the shape you want.
  • To cool the metal, dip it in water. Make sure your face is nowhere near the bucket of water. This prevents the steam produced by the metal from striking you.

Accessories for a Bench Grinder

Wire Bench Wheel Brush

A wire bench wheel brush is ideal for removing corrosion and paint. You can use a wire bench wheel brush to eliminate some burns as well. This is also the tool for blending and tidying up surfaces. There are different types of wheel brushes. Some are for heavy duty use and others for light and medium tasks. When shopping for these, look for one that is solidly built.

Bench Grinder Stand

A bench grinder stand (or pedestal stand) has a simple but important function. You use it to steady a bench grinder. An ordinary table won’t do because some grinders vibrate. This leads to clutter and affects performance.
A bench grinder stand is constructed to prevent that from happening. Different styles are available. All the good ones however, are made from solid steel or cast iron. They are also well-balanced and come in different sizes.

Grinding Wheel Dresser

A wheel dresser has several uses. You can use it to dress and clean up wheels and get an even surface. The best wheel dressers take only a minute or so to get the job done. A grinding wheel dresser is also handy for removing metal buildup.

Bench Grinder Buffing Wheels

For optimum performance you’ll want those wheels clean and shiny. That’s what you get with bench grinder buffing wheels. There are different types of buffing wheels, but they generally work the same way. It’s like using sandpaper except the motor does the heavy work.
Buffing wheels provide different levels of smoothness. Before you buy one of these, make sure it’s got the properties and features you’re looking for. Keep in mind there are lots of these products so some research is going to help.

Safety Tips

  • Do not touch the workpiece ground part until it has cooled.
  • Even the best bench grinders cannot work with small stock. Do not shape, sharpen or grind anything the tool rest cannot handle.
  • Move the object into the wheel smoothly and slowly.
  • Never use a vibrating wheel. If it suddenly vibrates, turn it off.
  • Adjust settings only when the grinder is unplugged.
  • Don’t wear jewellery or loose fitting clothes.
  • Wear safety glasses, a face shield and side shields. I also recommend hearing protection.
  • A two foot perimeter is recommended around the bench grinder. This area should be free of debris and people.

Maintenance Tips

  • Read the instruction manual that came with your bench grinder. Follow the directions for cleaning and maintenance.
  • Use a compressor to get rid of dust buildup. Wear goggles.
  • Do not use solvents or detergents to clean the grinder.
  • Inspect the grinding wheel regularly. Look for signs of wear and tear. Replace immediately if there are signs of cracks or it is worn out.
  • Some manufacturers recommend oiling the rotating tool shaft every 5 or 6 months.
  • As the best bench grinder reviews will show, these tools work with specific types of wheels. Use only the ones indicated in the user guide.

My Recommendations

My best bench grinder reviews show why these five are the cream of the crop. However, I recommend either the DEWALT DW758 8-Inch Bench Grinder or the WEN 4276 6-Inch Bench Grinder. The DEWALT DW758 8-Inch Bench Grinder is easy to use, and its motor makes material removal quick. It’s very suitable for large projects.
The WEN 4276 6-Inch Bench Grinder is just as good. It gets my vote for being lightweight yet fully functional. The inclusion of a light is a nice touch and the grinder does what it’s supposed to do. It’s nothing fancy but as far as functionality is concerned, the WEN 4276 runs fine.

Final Word

Bench grinders come in different styles and functions. There was a time when these tools were beyond the reach of most. But now the cost has gone down while efficiency has increased. Along with that is the number of bench grinders to choose from.
If this is your first time to buy, figuring out what the best bench grinders are can take a long time. With the information I have presented here hopefully you’re now better informed. Whether you’re new to this stuff or have been using it for a while, being updated is essential. Good luck!
