Gearwrench 3/4-Inch Electronic Torque Wrench Successfully Blends Technology And High Strength
Any mechanical engineer will tell you that proper torque settings can be the difference between success or catastrophic failure. The Gearwrench 3/4-inch electronic torque wrench is designed with both the brains and brawn to tackle high-torque jobs and with outstanding precision.
Gearwrench 3/4-Inch Electronic Torque Wrench Electronic Benefits
Digital Display
As an electronic torque wrench, you need a power source. There are some rechargeable options out there, but Gearwrench sticks with the simplicity of two AA batteries.
While you’re working, the screen tracks your progress and displays the maximum torque value you hit.
Gearwrench’s digital display is also where you’ll set the Warning Torque Percentage as well as your desired unit of measure. Think of the warning percentage as a sort of yellow traffic light. You can set the warning percentage from 5%-50% depending on your preferences.
To set the value, push the (%) button and use the arrows to navigate. Once the display shows the percentage you want, push the (%) button again to save it. Press (CLR) to clear the warning torque values.
Setting the torque value is basically an identical process. Press the (SET) button and use the arrows to scroll. A second press of the (SET) button saves your selection. Clearing set values is the same process as before.
Precision Haptic Feedback
A nice feature of the Gearwrench 85082 is the visual and audible feedback you get through the torquing process. As you approach your targeted torque setting, you’ll hear the buzzer start to chirp and the green LED illuminates.
When the torque reaches the target value, green and red LEDs light up and a buzzer issues a continuous long “beep” sound. In addition to the audible alerts, the handle will begin to vibrate when the applied torque reaches your target value.
If you exceed your target torque, the buzzer sounds a constant tone and you’ll continue to feel a mild vibration in the handle.
If the torque exceeds the maximum 750 ft-lbs, the display will read “—-“, both LEDs will light up, and the buzzer will issue a continuous long beep sound.
Accuracy
When the job requires precise high-torque specs, the 3/4-inch Gearwrench electric torque wrench has the strength to back it up. It delivers 70-750 ft-lbs of fastening power with a ±2% margin of error on torque.
You can set the torque wrench to measure and read out in ft-lbs, in-lbs, Nm, Kg-m, and Kg-cm. Plus, it saves the last torque setting you used, which is kind of nice. Simply press the (UNI) button to scroll to your preferred unit of measure.
Gearwrench Electronic Torque Wrench Design Notes
High Torque Needs High Leverage
The length of this wrench makes it very easy to achieve high levels of torque. On our torque testing rig, we were able to easily tighten 1.5-inch Grade 8 nuts to 600 ft-lbs for our impact wrench testing.
Avoid the temptation to use a “cheater” pipe when you’re getting close to the upper torque limit. The precise nature of the internal mechanism makes it susceptible to damage if you over-torque a bolt.
Ergonomics
Gearwrench makes sure that the whole process of measuring torque feels as comfortable and natural as possible with such a large electronic torque wrench. The textured metal handle offers a decent grip if you’re using it bare-handed. The handle and housing are oil and solvent-resistant, so your greasy hands won’t gum it up too bad.
Access
The teardrop-shaped head does a nice job of getting into tight spaces. One thing to watch for is that while the 24-tooth pawls are super-durable, they need 15° of arc swing to work with.
Calibration
Gearwrench ships the torque wrench with an ASME certificate of calibration. Because of its precision nature, we recommend you have it recalibrated once a year. Torque wrenches are more delicate tools than they look and accuracy can get thrown out of whack with as little effort as accidentally dropping it off the workbench.
That’s why we appreciate that Gearwrench houses this torque wrench in its own blow-molded hard case. When we’re not using it, the wisest course of action is to keep store your torque wrench in its case to avoid any inadvertent “calibration adjustments”.
Who It’s For
In terms of fit, a torque wrench of this size is something you’ll find in the arsenal of an industrial mechanic or heavy equipment tech.
If it’s more than your typical job requires, Gearwrench has a wide array of torque wrenches if you’re in the market, including 1/4-inch, 3/8-inch, and 1/2-inch electronic models.
Gearwrench Electronic Torque Wrench Price
This is a premium torque wrench made from alloy steel with a full polish chrome finish. Expect to pay around $899 for this model. With that, you get a sturdy hard case, a 90-day calibration warranty, and a 1-year equipment warranty.
The Bottom Line
What we really love about Gearwrench’s design is that it’s a durable, industrial-quality build with electronic feedback that makes it easy to know when you’re nearing and reach your target torque. Dealing with torque ratings up to 750 ft-lbs can be a pain, but Gearwrench makes it more convenient and lets you fasten with more confidence with this 3/4-inch electronic torque wrench.
