Buying Guide for Electronic Torque Wrench
It wouldn’t really be a complete review without a buying guide for the torque wrench, would it? Well, to have the utmost confidence when selecting a wrench, here are some of the major factors you should pay attention to find the best cheap digital torque wrench out there.
The Alert Features
Whereas the micrometer torque wrenches come with the click feature which allows you to hear and feel the click, we at least expect something similar and of course more from an electric torque wrench. Usually, many models feature red light, and beeps warning as torque alerts.
Most of the digital wrenches cost way more than the micrometer torque wrenches hence it really would not be fair if the alert features were handicapped, right?
The Digital LED Alerts
The reason as to why most people get top digital torque wrenches is because they can be able to use these in poor lighting conditions as well as somewhat noisy environments due to LED flashing.
In order to let you know that the needed torque measurement has been reached, the LED display or LCD display in most cases, flashes a few times. This way, you will not put too much stress on your bolts which could result in damaging your equipment.
A Vibrating Handle
This can be compared to the click only that it is not as subtle as the click- trust me, you’ll know the difference if you use the two-.
The vibrating handle works in such a way that as you approach the set torque limit, the vibration gradually increases and once you hit the set limit, the torque vibrates as well. this could be handy in noisy environments when hearing a click from a micrometer torque wrench is difficult or also when seeing the LED alert is a problem.
The Buzzer Notification
I’d consider the buzzer notification a must-have for any good quality electrical torque wrench and the reason for this is due to the conventional nature of the click type torque wrenches and the familiarity to knowing the torque limit is attained by hearing the click.
If you are moving from the click-type torque wrench to the digital torque wrenches, this is something I’d recommend you pay attention to.
With the buzzer notification, as compared to the click, you can hardly miss on this when you reach the set torque limit and if it is backed up by the other alert settings, there’s no way you could miss out on the alert once you hit the set torque.
The Torque Directions
Yet another thing that is worth looking into when choosing an electronic torque wrench is the ease of usage of the torque wrench. The rule of thumb when choosing any torque wrench basically is the easier it is to use, the better a torque wrench it is.
Most torque wrenches allow you to only apply the torque in the clockwise direction. This, however, makes it somehow difficult to use it both right-handed and left-handed.
In addition to the difficulty of using the torque wrench with your dominant hand, something else that you are limited to if you can only be able to apply the torque in a single direction is when you are needed to use it in hard-to-reach spaces such as under your saddle.
Though most manufacturers tend to overlook the importance of applying the torque in both directions, it is something worth taking into account while shopping for a good digital torque wrench. Another thing you should check is the swing arc of the tool.
A Comfortable Handle
Now, as you look for a torque that gives you the convenience of applying the torque in both the clockwise and counter-clockwise direction, it would probably be a good idea if you also go ahead and select one that’s got a really comfortable handle.
If say you’re just from greasing your bike parts or oiling them and your hands are all slippery but at the same time you’d like to tighten some bolts and be done with everything before you clean up, you’ll want the handle to give you the best level of grip, right?
An Ergonomic Handle
The first thing you should consider looking into is how the handle is shaped. Such a handle should comfortably be able to fit in your hand perfectly well once you tighten your grip around it. This saves you from any unnecessary fatigue and the odds of it slipping away are quite slim.
Speaking of slipping away, let’s have a look at what you should get on your torque wrench handle to prevent this from happening, shall we?
A Non-Slip Rubber Grip
The best handle for slip resistance would be a rubber grip. Naturally, rubber is not only soft but it also does allow for friction when clenched down on.
If you can’t get a rubber handle, I’d recommend that you consider choosing one that’s made of plastic. In some cases, you might get a torque wrench with a metallic handle and in all 3 cases, it would be a wise choice to have one that’s got ridges on it.
NOTE: from my experience with torque wrenches, it is a good idea to go for a wrench with a torque wrench with the least amount of plastic or rubber since doing otherwise might compromise on the overall strength of the torque wrench.
The Number of Torque Measurements
Yet another thing worth looking into is the units of measurement that the digital angle torque wrench allows for. The rule of thumb as far as the ideal digital wrench is concerned is that it should allow for more than just one unit of measurement.
Manufacturers have different specifications for torque units and it would be somewhat cumbersome to use an alternative limit as you’d have to do a lot of conversions which are not always guaranteed to be correct. Also, some equipment has torque measurements on specific values so you can choose one also depending on your area of expertise.
The most common torque units are inch-pounds, kilograms per centimeter and even kilograms per meter. For the sake of versatility, it would be wise to choose a torque wrench that has got at least two of these.
The general rule of thumb in choosing digital torque wrenches is the bigger their size, the higher the torque levels they can attain.
For finer torque adjustments, you’ll want to go for something that’s small in size and for coarse adjustments, going for something that’s larger is a good idea.
Not, taking these two scenarios into account, I’d advise that you get more than just one electronic wrench unless you are really specific about how you are going to use the torque wrench. Size is also an important factor to purchase the best bike torque wrench out there.
The Accuracy Level
Being the most important feature to look into when selecting an electronic wrench, the level of accuracy varies from one manufacturer to the other.
Whereas getting the highest level of accuracy should be a priority, getting a wrench with a high accuracy level, yet again would mean that you get to spend a little bit more on the same. So, that being said, here’s the way to go:
The recommended threshold for accuracy is +/-4%. If you’re using the torque wrench for finer adjustments, it would be a good idea for you to have a higher level of accuracy hence the 4% would increase to 3% or 2%. Sometimes a product will have features like gear sensing system, and target setpoints to ensure greater accuracy.
Clockwise vs Counter-Clockwise Accuracy
Still, on the accuracy, it is important that you consider the fact that some angle torque wrenches do have both the clockwise and the counterclockwise torque adjustment capabilities. Regarding this, I’d recommend that you go for an accuracy level that is at least +/- 2% for the clockwise torque application and +/-3% for the counterclockwise torque application.
At the end of the day, you’ll want something that’s got a high level of accuracy depending on how you’ll be using the wrench. It is therefore always important to pay attention to what you’re using the electric wrench on demands regarding the accuracy.
With an electric torque wrench, it might seem that visibility is not a problem at all but this is not always the case. As much as the wrench may have an LED display that’s easily visible in the dark, some of these are not as visible out in the sunlight.
To ensure it is easily visible at any time of the day, always go for a high contrast scale as this would work perfectly well even when used out in the sun.
Extra Features to Take Into Account
Wrapping up our buying guide on the top electronic wrenches, I’d like to shed some light on some extra features you should consider taking a look at for added convenience while using your digital torque wrench.
A Storage Case
Though this is more of a priority for the click type wrenches, it is worth having for a digital torque wrench. The last thing you want is spending a lot of cash on a wrench only to have it deteriorate in quality from bouncing against other tools in your toolbox.
After all, with a storage case, it would also be easier to carry your wrench around your workshop and definitely harder to lose it.
Most digital wrenches normally have the data storage feature and from my own point of view, it’s a good idea to get one that allows for the storage of some values. The rule of thumb is the higher the number of storage values it can accommodate, the better the electric wrench is.
Automatic Shut-Down Feature
All digital torque wrenches use either a rechargeable battery like AA batteries or just the usual batteries and it would be a good idea if you optimize their usage. The best way manufacturers make this possible is via the auto shut-down feature which is triggered after about 2 minutes hence conserving the battery power.
A Charge Indicator
Besides the low battery level indicator, always look out for the charge capacity indicator since this lets you know when it’s nearly time to swap the battery. If you ask me about battery type, then I’d suggest that you go for lithium-ion batteries as they last long.
Since these items are quite expensive, you would want them to be long-lasting. The construction of the tool should be done with high-quality materials only. If you see stainless steel and chrome finish used in the device, usually it’s a good sign. It would be great if they come with a warranty as that would mean that the company trusts its products.
How to Calibrate a Digital Torque Wrench
Calibrating a digital wrench is really easy. Unlike the traditional wrenches, it doesn’t require you to rotate the handle again and again.
The wrench will come with a digital display, on which you can set the torque. Thanks to the digital display screen, it’s easy to read the torque amount.
A few of the wrenches will warn you when you are getting closer to the set torque. It helps to minimize mistakes.
However, keep in mind that the electronic wrench runs on battery, so always make sure it has an adequate amount of battery life in it.
