In the world of cordless torque wrenches, few tools have come further in-terms of quality than the battery-powered torque wrench. When we wrote about these wrenches a few years ago, we offered several caveats, such as the fact that the tools had a shorter battery life.
But in 2020, battery powered wrenches -- particularly the ones offered by RAD tool -- are among the best cordless torque wrenches.
- The weight of the battery in these cordless torque wrenches is substantially lower than on earlier models.
- They offer electronic features not included on pneumatic torque tools.
- There’s no power cord or airline involved, allowing operators to use these tools on jobs that require them to work in smaller spaces.
- They feature an automatic release function that activates once torque is applied to a bolt.
Among RAD’s cordless torque wrenches is the Digital B-RAD tool, the world’s first cordless, digital and battery-powered tool with a digital display and single increment torque settings. These tools also feature:
- A lithium ion battery
- Dual scale, reading ft./lbs and nm.
- LED indicator lights
- Integrated calibration
In addition, each tool features a:
- Reaction arm
- Choice of either a simple screen or digital display
- Two batteries and a charger
- Retaining ring
- Storage case
- Operations manual
Lastly, this wrench will arrive with a calibration certificate, giving you peace of mind that you’re working with a tool that has ISO-17025 accreditation.
This tool provides unrivaled power and reliability from a cordless torque wrench that’s portable and lightweight, perfect for jobs where electrical tools or compressed air connections are either unavailable or impractical.
Other benefits of the BRAD include:
- Controlled torque capable of +/- 5 percent accuracy and +/-2 percent repeatability.
- High power-to-weight ratio
- An ergonomic pistol grip which reduces operator strain and prevents injury.
What’s the difference between the BRAD vs. the D-BRAD?
RAD makes two battery-powered wrenches, the B-RAD and the D-BRAD. While these cordless torque wrenches have similar names, there are some key differences between them.
While both tools are fully ISO 17025 calibrated to an accuracy of +/- 5% F.S, the DB style torque wrench can be set to 1 ft/lb. or NM increments, while the B-RAD can be set at every 10 ft/lbs. or NM.
The B-RAD wrench has a brushless motor and carries an approved Class 1, Division 2 intrinsically safe certificate. This same motor allows the B-RAD to operate in certain volatile environments. The DB-style tool has a brushed motor and does not come with this safety certificate.
DB wrenches come with a two-speed style gearbox, while B-RAD tools are available in single speed and two-speed configurations. But the B-RAD brushless motor is generally faster and provides a higher RPM.
Unlike the DB wrench, the B-RAD automatically releases torque -- or backs off -- from the bolt once final torque is applied. This removes the need for the operator to reverse the tool to get it to detach.
Pre-Set Torque Set Up
DB cordless torque wrenches have a digital controller which allows the operator to set up to eight pre-set torque settings on the screen. The B-RAD tool doesn’t have this feature.
