Single Gear vs Multiple Gear Cordless Impact Drivers
Single-gear vs. multiple gear
|
||||
|
|
||||
 |
Simply put, gears alter the amount of torque and speed being delivered. Some cordless impact drivers only have 1 gear, others have 2 or more. | |||
Single-gear impact drivers |
||||
 |
Cordless impact drivers with a single gear allow you to vary the speed and torque within a single range.
This is done using the speed control trigger. |
|||
 |
Using the trigger, you can increase or decrease the speed and torque within the range offered.
For example, speed in the range of 0 – 2,400 RPM, and the torque in the range of 0 – 150 Nm |
|||
Multiple-gear impact drivers |
||||
 |
Some cordless impact drivers have up to 3 gears! An example of how these could be broken down is shown below.
Once you have selected the gear you want, you can use the trigger to vary the speed and torque between 0 and the maximum amount for that gear. |
|||
 |
Gear 1:Speed: 0 – 1,600 rpm For applications that require less power, first gear offers the least torque and the slowest speed. |
|||
 |
Gear 2:Speed: 0 – 2,150 rpm For medium-duty applications, second gear offers a slightly higher speed range and level of torque. |
|||
 |
Gear 3:Speed: 0 – 2,650 rpm For heavy-duty applications, third gear offers the highest level of torque and the fastest speed. |
|||
How many gears do you need? |
||||
 |
The more gears you have on your tool, the more control you will have when working.
If you want to use your cordless impact driver for a variety of tasks involving small and large screws, hard and soft materials as well as some drilling – then the more gears, the better. |
