Expert in Electrical Equipment

Clarke is Great Britain's leading manufacturer of electrical & mechanical equipment and tools for different purposes. Plenty of Clarke goods managed to overcome the competition in a variety of independent tests in order to win the 'Best Buy', ‘Best Pick’ and ‘Best Product’ awards. A lot of people all over the world choose to put their trust into the models of this manufacturer. Clarke's range of products is impressive on its own, including but not limited to power generators with digital control panels (featuring an Automatic Transfer Switch patented technology), propane fired space heaters, water submersible pumps, sharpening tools, air impact wrenches, and many others. If you need a high-quality tool, the one from Clarke is generally the right choice.

This CBG6RP is an outstanding representative of Clarke's powerful high-quality equipment line. The model is compatible with any kind of grinding wheel and you can get a replacement wheel in virtually any specialised store. This tool can be securely adjusted to a work surface and it comes included with a plastic base and 4 screw holes for attaching to a bench. What makes the Clarke CBG6RP such a versatile tool isn't just that you can change the grinding wheels to finer ones (if needed) but also the fact that you can even mount the tool for burnishing leather goods. Its owner can find so many uses for it, whether you want to sharpen your kitchen knife, shovel, axe, or prepare the drill bits for a more professional work.

Multipurpose and Applicable

The Clarke CBG6RP is a 6-inch bench grinder with a 150 W motor. This is a relatively low-powered motor that will not be able to tackle the tougher materials but will do an acceptable job when it comes to polishing and it is ideally suited for sharpening tools and blades. Some of the owners tend to change the grinding wheels for polishing wheels which they then utilise to polish some of their dull tools. Though you do have to keep in mind that 150W motor often becomes hot after 10-15 minutes of use (depending on the model of a bench grinder and a manufacturer) and should not be used for more than 30 minutes in a row without giving it some time to cool down.

All in all, what we have in our hands is an amazing bench grinder for sharping cutting tools with adjustable tool rests, a prominent base, eye shields and spark arrestors that protect the user from flying particles. The wheels have a medium grit making them a versatile fit for the majority of purposes. The grinding wheel features a 150 cm diameter, is 20 cm wide, and comes with a 12.7 cm bore.

People often tend to look for a high-quality appliance that isn't necessarily difficult to operate. Very few prefer heavy, loud, and complicated tools. And if you're a part of that majority, the Clarke CBG6RP may just be what you ought to be looking for. The device isn't particularly heavy, doesn't make too much noise, causes next to no vibrations and it doesn’t move while you’re sharpening your tools or working on any kind of applications (when it’s bolted to the working surface).

Affordable and Reliable

Silverline is one of those companies that, despite being recognised and trusted throughout the UK and Europe as one of the premier manufacturers of power tools and electric equipment, doesn't necessarily intend to sit on its laurels, all while trying to make as much money as possible by capitalising on their brand. Don't get us wrong, the company still offers exceptional products that boast the kind of quality you would expect from a premier developer of power tools, but they do that without asking their customers for a ridiculous amount of money.

And if you'd like an example of this practice, no need to look further than towards the Silverline 263511. The model in question is one of the cheapest bench grinders on the market with features similar to some of the more expensive products. This kind of price tag makes this device a great alternative for DIY enthusiasts who can not afford an expensive model but would still like to own a quality appliance. Although what we have on our hands can't necessarily boast the same level of performance as some of the best models out there, this mini bench grinder is more than appropriate for home use.

DIYer's Dream

This bench grinder comes equipped with 150 mm coarse (30 grit) and fine grade (60 grit) grinding wheels. The strong aluminium housing is the key to this product's sturdiness and durability. The 150 W induction motor is powerful enough to face even some of the rougher materials, producing considerable power for high-quality performance. Not to mention the fact that the aforementioned motor is fully water cooled in order to ensure its durability and that water cooling aspect is exactly what really separates this model from other cheap options. On top of that, Silverstorm's bolt holes and rubber mounting feet allow for bench mounting (meaning that it will not be making any movements while grinding). The on/off button is dust-protected and this kind of feature guarantees that any undesirable dirt pieces will not impact the insides of your device. This item will be a great fit for light and medium duty grinding tasks on metal workpieces, such as sharpening drill bits, cutting/shaping tools, and preparing metals for welding.

Another thing we would like to mention about this bench grinder is that this machine can even be used as a polisher. All you will have to do is attach a wire wheel to it and the device is good to go. The only real downside to this machine being a cheaper model is the fact that it starts to warm up after 10-15 minutes of grinding and should not be used for more than 30 minutes at a time without allowing it some time to cool down, otherwise the motor will not last very long. Though it is reasonably quiet and almost entirely vibration-free.

The model in question is certainly not a professional tool, but taking into consideration its price, this is one of the best DIY-level tools on the market.

This appliance comes equipped with a 150 W motor, which means it is capable of dealing with most DIY tasks like shaping and sharpening workpieces. But you have to remember that heavy duty tasks like grinding harder and rougher materials will generally present a problem for this bench grinder because it doesn’t have the power of some of the more expensive models. Nevertheless, this tool is perfect for most polishing work and lighter grinding work. It is equipped with standard 150 mm grinding wheels (one with a fine grit and one with a coarse grit) and these wheels can easily be replaced by polishing or wire wheels. Purchasing any of these wheels in the nearest speciality shop won't prove to be a problem either. The Einhell TH-BG mini bench grinder has 4 rubber feet for safe and low-vibration standing although it is often a bit of an unnecessary feature for this model since it has very low vibrations.

Fit for Most DIY Work

This tool is a durable one and it is featured with an integrated rubber bumpers, adjustable work supports, and sturdy compact metallic constructions, all of which are very robust. The TH-BG 150 tool rests are also adjustable and give you an amazing opportunity to perform various DIY applications. The Einhell grinder comes equipped with adjustable spark reflectors and guard hoods with closed sides that ensure safe operation of this tool, and zero-play ball bearing shaft that enables precise operations. While that may not necessarily spark the interest of seasoned DIYers, all of these features are perfect for less experienced users.

The 150 mm discs of this tool are divided into two; the coarse (K30) and the fine (K60) grinding discs. Coarse grinding wheel completes coarse grinding operations such as repairs and corrections very quickly and efficiently. While the fine grinding wheel performs precise operations like sharpening axes, drill bits, knives, chisels, and many more.

To sum it all up, the Einhell TH-BG is the kind of bench grinder that is highly versatile, reliable, very durable, provides smooth and quiet operations, is easy to clean and maintain, and, on top of everything else, comes at a considerably cheap price.

What Is a Bench Grinder?

That all cutting tools require occasional sharpening is a known fact, and for this purpose, until recently a lot of DIYers used to use abrasive stones. Fortunately, with the invention of powerful bench grinders, there’s no more need to hone tools manually. Today you can get a powerful machine and use it for all kinds of metal, polishing and cleaning your workpieces to perfection quickly and painlessly.

Also, you may consider reading our review on angle grinders that can help polish and shape the metal parts prior to their further processing, as well as the review on table saws that you can use for woodworking projects.

Best Bench Grinders

What Features to Compare

Power and Speed

Before you buy a bench grinder, define the jobs it will fulfill. Pay attention to the power and the number of revolutions per minute (RPM). The higher the power is the longer the grinder can work under heavy loads. The powerful benchtop grinders are the best for daily use in fitting shops. The models that work at higher speeds can sharpen the tools faster, yet the metal itself will get hot faster too and therefore, it'd be better if it's used by an experienced DIYer. Low-speed grinders in turn work at slower speeds, are used for a fine grinding of soft metals and much more convenient to use by novice users. 

Grinding Wheels

Grinding wheels are the next feature requiring your attention when choosing a benchtop grinder. The wheels are available in different thickness and diameter options. The larger the wheel diameter is the longer it will last and the more items you'll be able to process. Most bench grinders come with two wheels of different grits. One of the wheels usually has a coarse grit for rough grinding, sharpening, and milling, while another one features a finer grit for honing and finishing. The wheels are replaceable, and you can always choose a finer or coarser grit. Moreover, you can install felt and wire wheels as well. Don't forget to pay attention to the grinder's arbor size to pick the fitting wheel.

Conveniences

To make the usage of bench grinder more comfortable for a user, manufacturers tend to fit them with some little extras. We'd recommend you to go for a tool with a variable speed support so you could adjust the speed yourself depending on the type of material you process. A lot of bench grinders come with LED lights to allow you to use it under low-lit conditions. Since overheating is an often result of a long grinding process, some of the grinders include coolant vessels. For more comfort of use, you may want to consider purchasing a grinder with a tool rest where you could place workpieces. These rests can be notched to allow you to sharpen some smaller bits and scissors. Consider the package too as a lot of tools today are shipped together with eye shields that come useful during work with metal. 

FAQ:

Q: What is the best bench grinder for home use?
A: It all depends on what kind of work you're going to do. There isn't really a universal solution, but you can choose the most suitable one for your purposes. If you surely know that you will use this tool in your garage for sharpening kitchen knives or maybe garden shovels, you don't need a professional and powerful bench grinder. 150 W motor will be more than enough and, talking about other specs, you should just pay attention to the price/quality balance. If you are ready to pay a big price for this tool, you can choose any of the models from a famous brand, but if you know for a fact that you are not ready to pay much, you can choose the one from a lesser known brand which will be enough for amateur use.

Q: I'm a DIYer and I need the one for sharpening, which is the better option to buy?
A: It'd be better for you to look for a non-professional one. If you need a bench grinder only for sharpening, you don't really need a model with a really powerful (350 W and more) motor. Your search criterion has to be directed at "DIY tools" or any other interpretation of it.

Q: I bought a bench grinder but don't know how to use it. Where can I get information on how to sharpen tools on a bench grinder?
A: Firstly, before turning the grinder on, you have to make a safety check. Then make sure the grinder is tightly secured to the bench and check that the tool rest is in place on the grinder. The tool rest is where the metal item will rest as you grind it. The rest should be secured in place so there is a 1/8 inch (3 mm) space between it and the grinding wheel. Clear the area around the grinder of objects and the debris. Fill a pot or a bucket with water and place it near the metal grinder so you can cool off any metal that gets too hot while you grind it.

It's important to protect yourself from grinding dust. Wear safety glasses, steel-toed shoes (or, at the very least, no open-toe shoes), ear plugs or muffs, and a face mask.

Turn the grinder on and wait until it reaches maximum speed. Rest the piece on the tool rest and hold it securely with both hands. Slowly push the blade into the grinder, angling it slightly up or down, so the grinder cuts the metal away in order to create a pointed, sharp edge. Use the same forward-and-back motion, rubbing the blade across the bench grinder to prevent cutting into the blade or warming it up too much.

Q: I need a bench grinder polisher to burnish my stuff. What model should I consider?
A: The majority of the models feature replaceable grinding wheels so you can mount a wire or polishing wheel on virtually any bench grinder. You just need to know how much pressure you will have to apply to your grinder and that will define the power of the tool's motor. Knowing the motor's power, you can just choose among different brands and that's only the matter of price.
