bench grinders Buyer’s Guide

If you keep the before points in mind, you can easily go out to the market and buy bench grinders, right? No!

Common Uses

I know I mentioned that bench grinders are for sharpening blades, but they can also be used for many other things besides this. Some other common uses for a bench grinder are grinding down rivets, smoothing weld joints, or smoothing the edge of wood after it has been cut. On top of this, you can also use it to repair cold chisels, drill bits, plan irons, and knives or cutting tools. This means that once you have a bench grinder you will probably be coming to it and using it more often then you thought. That is why it is a good idea to read reviews and invest in the best bench grinder you can afford. You don’t want to buy one now to have to replace it later because it doesn’t do everything you need it to do.

Spark Deflectors

The grinding wheels hook onto the side of the grinder and go into housings known as spark deflectors. These spark deflectors also known as wheel guards cover about seventy-five percent of the wheel, but the front twenty-five percent is exposed so you can use that surface to work. The spark deflectors like the name indicate tries to prevent sparks from flying towards you. When grinding on metal you especially get a lot of sparks, but even grinding wood sends fragments out. By having the grinding wheels covered it helps contain these fragments so they don’t get all over your shop or into your skin. Another function of the housings around the grinding wheels is to help keep your fingers or other objects out of the grinding wheel. You have to work carefully not to get your hand to close when grinding because the wheel will act like sand paper on your skin and flatten and cut into it just like it would the metal or wood. Also, if the vibration causes something to fall onto your bench grinder or you accidentally knock something off of your bench because you didn’t keep the area clean and organized the spark deflectors keep the falling object form hitting the grinding wheels and shooting wherever.

Eye Shield

Another part that serves a similar function to the housings is the eye shield. This part is generally a clear plastic and is located above the opening where you can work your material on the grinding wheel. This is an added precaution to make sure that any scraps to not come up and hit you in the face or eyes. However, it is still good practice to wear eye protection when working with a bench grinder. It is better to be too safe and not get hurt then to not be cautious enough and end up with an accident happening.

Choosing the Right Wheel

When choosing a bench grinder wheel it is important to pick one that is designed for the job you are doing. You also want to make sure it is rated for the speed of your grinder. If you use a wheel on a faster setting than it can handle, then you could end up with the wheel exploding. This can still happen with proper use and that is another reason for the wheel guard, but it is much less likely to happen if you take care of your wheels and use the proper ones.

Straight Wheel

The most commonly used wheel is the straight wheel. It produces a concave surface which makes it good for sharpening chisels and other tools. Any type of surface grinding can be done with a straight wheel, but they can also do the centerless and cylindrical grinding.

Saucer Wheel

If you got a lot of saw blades that need sharpened then you will want to invest in a saucer wheel. A few other wheels that exist, but are very specialized are dish cup wheels and straight cup wheels. If you have a used for one of these, then you will probably know what it does.

Cylinder Wheel

If you need a larger grinding surface than the standard horizontal wheels can provide, then you can get a cylinder wheel. They are hollow and have use vertically or sometimes horizontally if your grinder is big enough. They can go all the way up to 1inches so if you ever needed to grind a big sheet of metal all at once, then this might be the option you will have to use.

Aluminum Oxide Grit

The most common grit is the aluminum oxide and the most common colors are gray and brown. Color effects toughness as well as cost. The gray and brown are the workhorses thanks to the fact that they are inexpensive, but get the job done. They are general purpose and can be used on low or high carbon steel. Pink and white are used on harder steel which needs a cooler cutting action to avoid burns and they cost a little more than the gray and brown. Ruby red is the most expensive and is used on tool steel and is an especially tough grit.

Silicon Carbide Grit

Silicon carbide is normally black or green. The black is used on softer metals such as aluminum and even on plastic. The black silicon carbide is extremely sharp. Another area where it is used is of stone such as marble so if you want to grind the edge of a counter top it is the go to grit. Green silicon carbide is even sharper though then the black and used for strong metals such as titanium or plasma sprayed material. Silicon carbide can still be used on steel, but it is actually a finishing grit. It provides a nice polished surface when used on steel.

Ceramic Grit

Ceramic is a newer grit that is available. One advantage of ceramic is it doesn’t dull. Instead, it fractures into sharper pieces as you use it. This is cool and saves time and money on having to resurface your grinding wheels. The downside, however, is ceramic wheels are expensive and most wheels only mix a little ceramic with another type of wheel. Due to the cost, it can be hard to find a profitable way to use ceramic wheels, but as time goes on they may become more affordable or you may find a special use for them that makes them work for you.

Grit Sizes

Next, we get to grit size which effects the finish you get when grinding. Grit is generally in four categories which are coarse, medium, fine, and superfine. Course grit is those from 16-24, medium from 36-60, fine from 80-120, and superfine from 150 on up. The coarser the grit the faster material is removed. This makes work quicker but leaves a rougher surface. When you want to remove less material and start working on the finish you move to finer grits till you have it ground and polished the way you wanted.

Grit Hardness

The last aspect of the grinding wheel that I will cover here is hardness. Hardness is rated from A-Z. “A” is the softest and “Z” is the hardest. The harder the material you are working on the softer you want the grinding wheel to be. The harder the wheel the longer it will last, but you don’t want it to be too hard that it damages what you are working on. Also, it is important to stick with one manufacturer when buying wheels because one companies “F” hardness could be another company “G” hardness. There is no set standard on how hardness is rated across brands.

Fine Wheel

You can also get a fine wheel instead of a course wheel. The fine wheel is generally a brush that is used for polishing. The advantage to having a fine wheel on one side and a course wheel on the other is you can grind and polish right back to back. The down side is a fine wheel takes more care to take care of.

Select the Stone and the Right Speed

As for using a bench grinder, it is simple. You put the proper stone on it for the job and then you set it on the right speed. After that, you guide the tool careful and gentle into the grinding wheel. The key thing is you want to make smooth movements. You don’t want to be jerking or get tired while using it. You want to be comfortable.

Set the Right Speed

When using the grinder you also want to make sure you are using it at the right speed based on the wheel being used. You have to factor in the wheel material, but also the material you are grinding. As you grind heat builds up and this can cause the wheel to wear. You don’t want the wheel getting too hot or it can fracture or explode. You can sue coolants to prevent this, but that isn’t always the best option. It is better to be safe and work at a slower speed than to go too fast. Another thing that affects how fast a safe speed for the wheel is, is the wheel size. The bigger the wheel the slower you need to go. Just be sure to read the packaging of the wheel you are using.

Use the Proper Angle

The proper angle you use depends on the material and the job you are doing. If you want a sharp edge on something then you will have to use a sharper angle. If you are just using the grinder as a way to sand some material or polish some material then you may not need as much of an angle. One key thing to remember though is you want to keep your pressure forward. The wheels are designed to handle pressure coming down on them from the front and top. You never want to try to use the edge of the wheel or use it from the side. You may think you can get more use out of the stone, but this can heavily damage the grinder. This can cause the router to warp from the pressure and can also cause the stone to be damaged. Always keep the pressure forward and don’t try to extend the life of the stone by putting yourself at risk by using the side.

Coolants and Rolling Pan

Back to addressing the issue of friction and overheating you have to option for coolants. There is a dipping pan option where you dip the metal you are working with into the coolant. This is method is convenient and quicker. By having a dipping tray you don’t have to wait for the metal to cool down while working on it. The other option is a rolling pan. The rolling pan cools the stone as it spins. By cooling the stone you are not actually cooling the metal so the metal could still warp as you work on it. That is why generally the dipping pan is a better option, but the dipping pan doesn’t protect the stone from heat. You could always combine the options to protect everything.

View Product

This is a convenient bench grinder for buffing, sharpening, and grinding as well as polishing. Its speed range is up to 3400 RPMs and has a variable speed dial. This model uses both 60 and 3grit wheels for grinding and sharpening. The drill bit rest is milled into the Grinder which helps ensure you get the right angle on the tip.

Tormek T-Sharpening System

If you are looking for a system that gives you professional sharpening application the Tormek T-Sharpening System combines the precision of an angle guide with the durability and slow speed of a grindstone.

The T-uses the Diamond Truing and Dressing Tool with the Square Edge Jig to increase accuracy and safety.

For precision sharpening, the SE-7Square Edge Jig aligns automatically while the Diamond Truing and Dressing Tool protects the stone and keeps it in perfect condition that is necessary to make a perfectly sharpened edge.

Unlike dry grinding, the wet grinding process uses less friction and removes less material from your tool as you sharpen it. You also don’t have to worry about overheating, burr build-up, and have to sharpen tools frequently.

It also comes with eleven jigs that will work with most knives, industrial tools, and woodworking tools.

The jig is also adjustment free as it aligns squarely for quick clamping, unlike conventional jigs that make you align the tool in the jig with mounting screws. It can also handle blades that are up to inches or 7millimeters in width, plus it includes safety stops so the tolls don’t slip from the stone.

The Tormek T-also features a heavy-duty motor that provides 90 RPM with a inch by inch stone wheel that can be run continually.

Stone Size

If you are doing smaller projects like sharpening household knives or tool sharpening, a small grindstone is sufficient. For larger, heavy duty jobs, a larger grindstone is necessary. When looking to purchase a grindstone, make sure you get a stone that is the correct size for the projects you have planned.

Purpose

First the of all you have to know your purpose. I mean why you are purchasing the bench grinder? What will you do with the machine mainly? Ask yourself both the two question. Not all the bench grinder is suitable for all-purpose works. If you need one for small projects, you have to think about the smaller versions. If you need one for large projects, you have to consider more extensive options. That’s the basic idea.

Motor power is another most important consideration. The bigger the motor, the more powerful it will be. If you need to grind a large area quickly, a powerful motor has no comparison. At least search for a bench grinder that has 1/horsepower motor with 3000 RPM speed. If you are a newbie, a slow speed model will be suitable for you. Therefore, some of the bench grinders have dual speed options or adjustable speed control setting included. Those are more useful. But to purchase that type you have to spend a bit more. If you are a beginner or you often work with different types of materials a bench grinder with multiple speed setting is what you need.

How to choose the Grinding Wheel

There are some certain factors you need to consider while choosing grinding wheel. The most important factor is the material by which it is made of.

Wheel Size

Wheel size is another most important factor in a bench grinder. How can you use the grinder and how fast the task will be done is depending on the wheel size. to inches size wheels. If you want to do both smaller and larger task to inches will be suitable for you.

POWERTEC UT100Universal Tool Stand

The tool comes with two high-quality Norton wheels. One wheel is an 80 grit 3X blue ceramic alumina K grade high-performance wheel which is for coarse grinding. Another wheel is a 100 grit white Aluminum Oxide which will help you especially is finish grinding. These two wheels get power from a horsepower high-performance motor. The motor is mounted independently inside the tool base ensuring easy access and service.

This slow speed tool has a wheel speed of 1750 RPM which will allow you to perform optimal sharpening of common tool steels precisely. The base is strong to keep the tool in place at the time of running by reducing vibration. There is an integrated paddle switch with the tool having a safety key.

Silverstorm 263511

One other thing to remember with the 26351is that the machine starts to warm up after 10-15mins of grinding and should not be used for more than 30 minutes at a time without allowing it to cool down, otherwise the motor will not last very long. It is reasonably quiet, but vibrates a little bit so it does need to be bolted down to the workbench.

Draper 66804

Draper 6680bench grinder houses a 250W motor making it a more powerful grinder compared to the budget 150W models. Having said that however, it is still by no means industy level, and the Draper 6680remains firmly in the DIY / hobbyist camp. The Draper 6680can sharpen tools, knives and even large lawnmower blades, but it will struggle with some harder materials. In addition, the more powerful motor does not mean that it can be used longer than lower power bench grinders as the motor will heat up over the course of 15-30 minutes of use and will need to be allowed to cool down at frequent intervals if the motor is to have a long life. The more powerful motor also creates more vibration and the 6680will need to be bolted down to the bench-top using the holes in the base of the unit, however, it should be noted that these are of a smaller diameter than we would have liked.

Draper 29620

Draper 29620 is a middle-of-the-range bench grinder with a 370W motor allowing it to handle some heavy duty grinding. In general, it is solidly built, the wheels are well-balanced, running smoothly with little vibration. The machine comes with 3grit and 60 grit grinding wheels, which are a little too corase for delicate blades, but as with most other bench grinders the grinding wheels can be swapped out for other types of discs if need be.  The unit weighs a hefty 1kg so it is unlikely to move much but it can be bolted down to the workbench using only two holes in the base of the unit. Overall it is a good medium-level machine, however, it is let down by the inclusion of less-than-adequate tool rests which can deform when grinding something substantial, and the fixings of the tool rests and various other components on the machine, are woefully below the standard of what is otherwise a good machine.

Draper is a large and well-known player in the DIY and trade professional arena producing a wide range of power and hand tools. However, with Draper, it can sometimes be a bit of a lottery as to whether you get a perfectly built tool as quality control at Draper seems to slip up once in a while and lets through some substandard units. Sometimes it is a matter of going though a couple of rounds of returning substandard items until you are satisfied with the unit you have received.

Record RPBG8

On the positive side, the machines house a powerful 370W (RPBG6) and 500W (RPBG8) motor that are able to tackle most grinding and polishing jobs. The bench grinders come standard with a wider fine grinding wheel, and both wheels, if properly adjusted, run true and with little vibration. This together with an extensive warranty makes the purchase of either bench grinder a compelling prospect. On the negative side, the spark guards are poorly-made, and one would expect the tool rests to be better designed on a reputable machine. In addition, the manual is poorly-written (by a native of China is our guess) which is always a bad sign, and particularly ominous from a company that prides itself on living up to British standards.

Tormek T-Water Cooled Precision Sharpening System
