I do not need to emphasise much on its excellent build quality because since it’s entirely on the visible side. The bench grinder also has beautiful architecture (maybe it’s just the prominent eye guards and metal tool rests) and works with a reliable and efficient 3/4 hp motor at a terrific speed.

Best Bench Grinders – Buyer’s Guide

Best Bench Grinders Buyer’s Guide

That being said, we shall now lay proper emphasis on the things to consider when purchasing a bench grinder from the store. Some months back, I had a colleague who often complained about his bench grinder being inefficient for some of his works. Not until recently did I figure out that the model he bought (portable bench grinder) wasn’t good enough to carry out the specific kind of task he wished to complete in time and adequately.

As a result, we got an automotive bench grinder with adjustable speed settings to help maximize time during the tasks associated with it. The dilemma of my colleague experienced was merely due to insufficient knowledge on the selection of an apt bench grinder for the nature of most of his projects. Intuitively, he was probably intrigued by the portability and ideal light weight of the machine which caused him to make a wrong choice.

In case you are a novice, an explained set of information has been provided for you so you don’t face such predicaments in life regarding your choosing skills. The primary factors to consider when looking for the best bench grinder are:

1. Motor Power

This property is usually labelled in watt (W) or horsepower (hp) depending on the model or country you intend to purchase the grinder. The latter is actually more common in most e-stores; but for the sake of unforeseen events, you might want to recall that 1 hp = 745.7W. By logic, the higher the value of the motor’s power means the more significant the power efficiency of the machine.

For instance, a bench grinder using ¼ hp will be 4 times less potent than a grinder using 1hp. For example, if you want to use the machine to sharpen a mower blade and do related tasks then the ¼ hp will be good enough for you. But if you need to really clean up your steel, or remove or shape the blade, the 1hp power motor will be ideal.

2. Construction & Durability

You surely want your investment to serve you for a long period of time. You need to make sure your preferred choice has a good build quality so you get good return from your investment.

3. Speed

Different top grinding machines come with wheels that are designed with variable speeds. Our research shows that a variable speed bench grinder is predominant amongst artisans and recommended for aiding optimum outcomes for projects. There are different types of wheels as stated below.

4. Types of Wheels

  • Straight wheel: It is the most popular of all types of wheel and is usually used for sharpening of chisels, gouges or similar tools. The straight wheel grinder is typically applied for tasks involving surface grinding or centreless grinding.
  • Cylinder wheel: This type of wheel is relatively large and hollow in design to be applied on huge, tough materials, such as large metal sheets.
  • Tapered wheel: Tapered grinder discs have their wheel narrowing towards edges. This design is mainly meant for exquisite kinds of tasks like grinding metal threads or sharpening of gear teeth during which the edges become tapered.

You can also choose from the dry wheel and wet wheel options when purchasing a bench grinder.

5. Safety Measures

I urge you also take proper safety precautions when dealing with bench grinders because there are quite a number of possible hazards that are accompanied by this machine if not adhered to.

  • Spark protection: No single glove is enough to provide complete protection for every work situation, so it may be imperative you get specialized (spark) protection when working with tools like bench grinders
  • Guards and tool rest: Make sure you have wheel guards in good condition for your grinding machine and set tool rest about 1/16 to 1/8 inch from the wheel
  • Anti-vibration feature: It is essential to reduce or limit vibrations of the grinding machine as they could cause poor surface finish or even accidents
  • Eyeshield: Guard your eyes while grinding to prevent grinding chips, metal pieces or little particles from contacting the eye
  • Rubber feet: It is ideal to mount your grinder to sit on rubber feet to subject it to firmness while you work on the machine. This can reduce errors or accidents when in use

6. Adjustable Speeds

With reference to speed being among the necessary factors to consider, bench grinders are best operated with an adjustable speed feature. It helps its user monitor and control the rate at which the wheels can exercise their performance on a workpiece so as to prevent uneven trimming or sharpening.

7. Warranty

A full warranty for your machine is a must-have, and it goes beyond that. The information should include a detailed explanation of the warranty coverage and what is not covered upon purchase of the bench grinder. More favorably, if you’re able to get a warranty for over 12 months then go for it without much hesitation. That way, you can account for the general performance of the machine for a longer time and feel secure about your budget.

8. Budget

You will find price ranges starting from $50 to as much as $600. On the other hand, angle grinders are cheaper when compared to bench grinders.

The Bench Grinder & Its Types

Bench grinders are commonly used to drive abrasive wheels, usually Aluminum Oxide stones, that sharpen or shape a workpiece (usually metals) for better efficiency. The various models of bench grinders invariably have a unique property that defines their purpose and the commonest bench grinders you will find are automotive, woodworking, and portable bench grinders. Some of them also come with a belt sander to help users grind and sand various materials.

Automotive bench grinders are quite the most prevalent type you will find around. This versatile machine can be used for grinding a whole range of cutting tools and shaping different metal equipment by the modern blacksmith. Consequently, an automotive bench grinder is designed to be stable with only a few adjustments to keep you going on the bench properly.

Woodworking bench grinders work per their designation – wood. They are specially constructed to smoothing cutting edges of woods that are dull and grinding wood, of course. This kind of grinder requires good precision and can be effectively gotten from a high-quality unit.

Portable bench grinders merely give us a hint that they can be transported around as preferred due to their lightweight. You can modify them to pedestal grinders with a sturdy stand. The only downside to this type of grinders is that they are not as strong as bigger grinders which may not be handy for tough metal works.

Why Use Bench Grinders?

So, what could be the reason that I would need a bench grinder for in my workshop? Considering the multiple metal and wood pieces I have there, I believe anyone who is need of a shaper or sharpener for optimum efficiency of these reference tools should keep a bench grinder at their arm’s reach. It may drive someone nuts when having to work on a project with blunt tools or inapt workpieces in general.

A bench grinder always makes our jobs more accessible by providing a flexible usage on our casual workpieces that tend to deteriorate over time. For us to keep all our tools in their nifty conditions from time to time, a bench grinder serves that purpose well. This is why it is recommended for construction specialists, tool based workers, or even homeowners. But you should also know how and where to use a bench grinder properly for maximum output.

Bench Grinder Care & Maintenance

Hunting out the top quality bench grinders isn’t enough, you need to take good care of the tool to make it long-lasting. Follow these tips and get served by your investment years after years.

  • A regular inspection on your grinding machine keeps you in-check for possible damage(s) in the nearest feature
  • Make sure you clean the machine when necessary. Remember to do this when unplugged or powered off
  • Lubricating the bench grinder from time to time improves the life cycle of its bearings
  • Cover up the machine when not in use for a long while and store in a safe place (dry, no solar heat contact)
  • Use proper cables to power the bench grinder. Failure to do so can cause interruptions and may even blow a fuse

It’s Time to Wrap Up

Who makes the best bench grinder? There are so many choices with different features and specifications that you may feel confused and not know how to make an informed buying decision. This merely tells us that when browsing among the numerous options, it takes more than just knowing the specifications. However, we were able to overcome this conservative perspective by reviewing more elaborate details about various grinders and their most remarkable, outstanding properties. Hope this article has given you sufficient insight on how to select an apt bench grinder. A better re-evaluation on reviews so to say!

Some reputed brands like Central Machinery, Bosch, Ozito, Creusen, Wilton, Hitachi, Wolf, Gmf, Task Force, Draper, Ryobi, Aeg, Linishall, Porter Cable, Parkside, Shopcraft, Kinzo, Waldown, Abbott & Ashby, Steel Grip, Mac Allister, Terratek, Ashland, Mastercraft, and Cummins Mack failed to match our benchmark. As a result, no model from them made it to our final list. Besides, vintage brands like Valley, Blue Point, Thor are now outdated and lack the required features to top among the new comers.

And in case you are still not able to make up your mind, compare the 8-inch grinders mentioned above, for instance, DEWALT DW758Jet 578008 and Metabo DS 200.
