Things To Consider before buying the Retractable Baby Gates

The first and most important characteristic is how well the grinder does its job- how powerful it is and the materials it can cut through, as well as how deep the cuts can be. There are a few different mechanical aspects like the RPM of the motor, the size of the cutting wheels, and so on. All of these combine to determine the strength and depth of the cuts. If you have a specific project in mind, then you can look up the hardness and thickness of the materials that you plan to use. You can then match your needs to a particular grinder.

On the other hand, if you do not have any particular goals, then you probably want a more general choice. The more certain you can be about how you will use the bench grinder, the easier it is to find yourself the right choice. Power costs money, so it’s risky to buy more than you need, in case you never actually use it. It is best to buy only what you need.

Specific Features

Bench grinders have assorted other features that can help you decide between them. For example, some are cordless and need to be charged, while others are corded and do not need charging, but you have to deal with wires. Other features could be that the grinder is particularly light, or has extra safety tools. In general, these features are good for choosing between different grinders that you already like, but they should not be the only thing on which you make a decision. Once you have a shortlist based on power and price, then you can use features to differentiate the best one. The sole exception is if there is some particular thing that you just have to have. These are by definition extra, supplementary. It’s always tempting to go for the grinder, that is loaded with features, but that is an easy way to overpay and wind up spending more than you intended. Much of the time, you will not find yourself using any very much anyway. If they will definitely inflate the price, do not bother. No extra feature is worth a major price increase, no matter how appealing the description makes them seem.

Ease of Use

When you have a bench grinder, you need to make sure it is easy to use. A lighter grinder or one with a better handle will be easier to hold. Because a bench grinder can be heavy and you need to be precise in your cuts, then the easier it is to use, the better you will do with it.

Some bench grinders are poorly designed and have bad handles or are awkwardly balanced. That makes it harder to follow a line and make the cuts you want to make. If you want to switch out the wheels for different types, then you’ll find that some grinders have quick-release mechanisms and other aspects that make it fast and easy to carry out the task, while others can be complicated. If you have a grinder that is tough to work with, then it will cause you annoyance every time you use it. It is worth it to invest in a grinder that won’t be aggravating. This is separate from the extra features section because it is more about the overall user experience of the grinder. As much as possible, try to get your hands on any potential grinder before you buy it so that you can see how it feels.

Durability

Best Bench Grinder for Sharpening and Home
Bench grinders can cost money. Moreover, they are often the best and only tool for a particular task. That means you should look for one that is going to last. You can get a rough idea of the lifetime of a bench grinder by looking at the included warranty. In general, a good bench grinder should last at least two years and preferably three as long as you are not using it excessively or trying to cut things that are too hard for the cutting edge. The longer the grinder lasts, the more value you get out of it. If you hold onto it for too long, it will perform less well, and the power of the motor will decrease. You also need to keep an eye out for mechanical failure and other wear and tear that could become a safety issue. You should also remember that you don’t necessarily want to keep a grinder forever- new grinders tend to add new features and characteristics, like better energy efficiency. That said, in general more durability and better construction is worth more to you in the long run than a cheaper, less durable choice.

Value

The last thing to consider is the value of the purchase. All of the features and aspects together have to be reasonably priced. Otherwise you will wind up spending too much on the grinder, leaving you not enough for other tools and materials for your project. As with other power tools, bench grinders have a wide range of prices. It is very easy to find yourself slipping higher and higher up the chain to the more expensive grinders. The best way to restrain this habit is to set yourself a budget before you look at a single grinder. Then refuse to even consider any choice with a price tag higher than the budget. That will preemptively remove temptation and make it easier to stick to your plans. Remember, every dollar you spend on the grinder is one that you cannot spend on anything else.

Full Detailed Review Of Bench Grinder for Sharpening

 

1. DEWALT DW756 6-Inch Bench Grinder

The DW756 from DeWalt is a 6-inch grinder that costs a little under $100. It has a 5/8 horsepower motor that reaches an RPM of 3450. It weighs 25.5 pounds and is fifteen inches long. The grinder is made of cast iron and aluminum.

The best part about the DW756 is the quality of the construction and the materials it is made of. It comes with a 3-year warranty, but you should expect it to last longer than that. It is fairly easy to use and adjust, and it comes with 36 and 60-grit wheels.

The DW756 is recommended for someone who wants a reliable and dependable 6-inch bench grinder. It doesn’t have a lot of bells and whistles, but it it is sure to last and maintain its function for a long time. The DW756 is a bit more expensive than some of the competition, but it should justify that price tag by lasting longer without having to be replaced than similar grinders from other brands.

Pros
  • Tough and durable
  • Comes with wheels and instructions
Cons
  • A little expensive

2. Sunex 5002A Bench Grinder with Light

The Sunex 5002A lists for $200 and, as the name suggests, is an 8-inch grinder. There is also a six-inch version. The main thing that sets it apart is the mounted light that makes it easier to see your work.

The 5002A has a 3/4 HP motor that gets 3450 RPM, same as the DW756. It is a little heavy at 36 pounds. The light is easy to adjust and move so you can get a good angle on your work. The wheel adjustments are easy to make and despite the weight the grinder is fairly easy to work with.

If you often find yourself in need of extra lighting up close to your grinding, this makes an excellent choice. It’s a feature that can be invaluable in the right circumstances. Aside from that, the 5002A is a little pricey, so make sure the light is really what you need. It does its work well- just make sure you get your money’s worth from the light.
Pros
  • Adjustable work light
  • Durable
Cons
  • Price is a little high

3. WEN 4276 6-Inch Bench Grinder

The Wen 4276 is one of the most popular bench grinders available for one simple reason: value. For about $35, you get a lightweight grinder that has a light, a motor that reaches 3450 RPM, and the usual two-wheel configuration, and it only weighs about 16 pounds.

The 4276 isn’t the best or easiest grinder to use. The light is a little bulky and the wheels are only 3/4 inch instead of a full inch in diameter. On the other hand, the motor is relatively quiet and fast to start up. The light weight makes it easy to control.

The Wen 4276 is by far the best value on the market. Make no mistake- there are better grinders out there, but none have the same combination of price, features, and build quality. Typically grinders this inexpensive don’t last, but Wen has provided a 2-year warranty. That ensures you will nearly match the lifetime of grinders several times the price of this unit. Unless you really need an 8-incher, this should be one of your shortlist options for almost any application.
Pros
  • Best value
Cons
  • Light is a little hard to use

4. POWERTEC BGSS801 Slow Speed Bench Grinder

The BGSS801 is an 8-inch grinder that runs at a slower speed for greater precision. The motor runs at 1725 RPM, which is half the usual rate. Everything about this model is efficient: the motor is quiet, the base is heavy for reduced vibration.

As a slow grinder, the operation of the BGSS801 might be a little different than you are used to. It’s better for fine work. But the unit performs admirably despite lacking notable features. It is smooth and consistent, with low-heat wheels and full inch wheels.

If you want a slow 8-inch grinder, it is hard to do better than the BGSS801 in terms of value. It costs about $100 but has an excellent build quality that improves user experience just as much as its durability. Expect a superior grind with a unit that will last. If you don’t have a goal that will explicitly make use of the slow speed and larger size, you should spend your money on a different grinder.
Pros
  • Smooth and quiet grinding
Cons
  • Not much in the way of extra features

5. SKIL 3380-01 6-Inch Bench Grinder

The Skil 3380-01 is a 6-inch grinder with a few extra features packed in that make it worth more than its $50 price tag. Specifically, it has a set of LED lights over each wheel for targeted lighting and adjustable tool rests, along with rubber feet to deliver better stability on the bench.

The 3380 works as well as a grinder twice its price, and the LEDs are very convenient. It is nice to have lighting without having to worry about adjusting and moving it. It is also on the quiet side just for a better user experience. The wheel angles are not adjustable.

The 3380 stands out because of the LED lights and other extras, but it also works well on its own as a solid midrange grinder in the 6-inch market. Look into it if you like lighting and you want a 6-inch grinder without spending too much money. It does have problems if you try to push it too much, so consider this a smaller and light-duty grinder if you don’t want to risk overwhelming the motor.
Pros
  • Strong value proposition
  • Useful feature set
Cons
  • Tends to slow down for heavy-duty operations

6. DEWALT DW758 8-Inch Bench Grinder

Unsurprisingly, DeWalt makes another appearance on this list. The DW758 is much like the DW756, but it is an 8-inch grinder rather than 6 inches. As with the other model, its biggest attribute is its durability, but it also boasts a powerful 3600 RPM motor for more advanced grinding. The base is cast iron and the rest is aluminum.

The weight of the DW758 is an asset, because it delivers exceptional stability even with the bigger demands that an 8-inch grinder job puts on the machine. It has rear exhaust ports and an adjustment guard that needs no tools to adjust, providing simple, yet powerful ability. It also has an overload protector to enhance the unit’s durability even more.

This unit is recommended for someone who wants a basic 8-inch grinder that will last for a long time and is easy to use. It lacks a light, but it is so good at its basic task that it is worth its price and more. It’s harder to find good value near the top of the market, but the DW758 pulls it off.
Pros
  • Good value
  • Durable
  • Useful quality of life features
Cons
  • On the expensive side for some people

7. JET 577102 JBG-8A 8-Inch Bench Grinder

The Jet 577102 is a straightforward 8-inch grinder that lacks features but has the grinding ability, as well as price, of a high-end machine. At over $200 it stands out from the competition for how much it costs, which is often a bad thing. In this case, however, it is justified by the powerful 1 HP motor and sealed construction.

As with the DeWalt line, the Jet is simple to operate and does not include much in the way of extra use modes or features. It is excellent at grinding because the engine is powerful enough to handle with ease tasks that other grinders would not be able to manage.

If you have a particularly tough material that you need to work on regularly, then it might be worth the price to shell out for the Jet. For most applications, a less powerful grinder will be enough for the job, but pushing a grinder too far can lead to overheating and other problems. This is a niche tool for people who can make full use of its motor.
Pros
  • Powerful motor
  • Durable
Cons
  • Significantly more expensive than competition

8. Craftsman 9-21154 Variable Speed 6-Inch Grinding Center

The Craftsman 9-21154 is one of a rare breed- a grinder that can adjust the RPM of the motor. This is an intriguing feature if you find yourself using both regular and low-speed grinding for different projects. At about $100 it is reasonably priced.
The Craftsman has a large lamp and some small extra features like a water cooling tray and a cast iron base. In general, it is easy to use and adjust, although the lamp is a little bulky. The power level is good, if unexciting.

The Craftsman is priced at an average or above average point for a 6-incher with a light, so it is really the variable speed that makes the difference. It is decent as far as vibration and durability goes. If you think you will want the variable speed, this is probably the best option you have. Otherwise, you can find other 6-inchers that have more features or better grinding ability for about the same price. That does mean you don’t really pay much extra for the special motor, which is a nice upside.

Pros
  • Variable-speed motor
Cons
  • Aside from variability, doesn’t bring much to the table

9. HRYOBI GIDDS2-3554576 6″ 2.1 Amp Grinder With Led Lights

The RYOBi GIDDS2 has a special feature that really sets it apart. It has an onboard voltage detector that has an electronic readout in the form of a bar chart on a small screen mounted on the unit. Separate from that, it also has a light. It costs about $60, so it is in the midrange market like the Skil model up above.

The performance of the RYOBI is adequate. It does not do anything particularly well or poorly, like a jack of all trades, but it certainly has a unique feature set. Moreover, this price range is ideal for getting a good product without worrying about its durability.

The RYOBI is perfect if you are interested in the voltage detector, because there aren’t really any other models that do this well. You are probably comparing this to the Skil or something similar, and it is hard to go wrong. Just choose whichever one has the better feature set for you.
Pros
  • Interesting voltage detection feature
Cons
  • Lacks much else in terms of features

10. Ironton 6in. Bench Grinder

At $40, the Ironton is between the middle and the bottom of the market. Accordingly, it has solid safety features and good construction with a basic 3650 RPM motor, but not much else.
The biggest concern with the Ironton is that it only has a 1-year warranty. That raises the question of whether it will last long enough to be the equal of grinders in the $50-$60 range. Other than that, it does grind well and it is easy to adjust.

The Ironton is a little better at grinding that the $30 grinders, but not as good value as the $60 ones. That places it in a bit of an odd spot. The motor is 1/2 HP, which is significantly better than some others in this price range.
Pros
  • Good value
  • Strong motor
Cons
  • Lacks features

Final Thoughts

Bench grinders are great tools because of how useful they are at removing rust and making other repairs. There are lots of good choices to select, and new models keep coming out with better motors, better construction, or new features. Keep your eye open for the latest and greatest. You certainly can’t go wrong with what’s available now, though.
