Battery-powered wrenches are among the most popular items we sell, so it makes sense that one of our most frequently-asked questions has to do with these torque tools:
“What is the difference between the RAD Digital D-BRAD battery torque wrench (or DB) and the RAD B-RAD battery torque wrench?”
And while their names might make them sound like interchangeable tools, there are some significant differences between these battery-powered, high-capacity torque wrenches.
In this blog post, we’ll explain the differences between and advantages of each tool.
Accuracy
Both tools are fully ISO 17025 calibrated, to an accuracy of +/- 5% F.S.
The difference here is that 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.
Intrinsically Safe
The B-RAD tool, with its brushless motor, comes with an approved Class 1, Division 2 intrinsically safe certificate. D-BRAD battery torque wrenches, with their brushed motor, do not carry this certificate.
Motor
The B-RAD has a brushless motor, while the DB has a brushed-style motor. The brushless motor allows the B-RAD to be used in certain volatile environments.
Speed/RPM
All DB wrenches are built with a two-speed style gearbox, while B-RAD tools are available in both single speed and two-speed gearbox configurations.
However, the B-RAD brushless motor is generally faster, and tool-for-tool gives the brushless tools a higher RPM.
Auto Back-Off
The BRAD style tool automatically backs off (releases torque) on the bolt after the final torque is applied, meaning the operator doesn’t have to put the tool in the reserve to get it to detach. Meanwhile, the DB style tool does not automatically release it after the torque is applied.
Pre-Set Torque Set Up
The digital controller on the DB battery torque wrench gives the operator the ability to set up to eight pre-set torque settings on the screen. The B-RAD battery torque wrench does not have that option.
Price
DB-style tools are about 10 percent higher in cost due to their programmable digital controller, allowing for the eight pre-set torque points we just mentioned.
