Single Gear vs Multiple Gear Drill Drivers
Single gear vs. multiple gear drill drivers |
||||
|
|
||||
 |
Simply put, gears alter the relationship between torque and speed.
Some cordless drill drivers only have 1 gear, others have 2 or more. |
|||
Single-gear drill drivers |
||||
 |
Some cordless drill drivers only have 1 gear. Using the speed control trigger, you can vary the speed within a single range of 0-600 rpm but no higher. | |||
 |
Squeezing the trigger increases the speed but decreases torque. The more you release the trigger, the slower the chuck will turn but the more torque the tool will deliver. | |||
Multiple gear drill drivers |
||||
 |
Cordless drill drivers with more than one gear offer the possibility to select different speed ranges.
The cordless drill driver on the left has two gears. |
|||
 |
In first gear, you can use the speed control trigger to vary the speed within the range of 0-350 RPM but no higher.
In second gear, you can use the speed control trigger to vary the speed within the range of 0-1200 RPM but no higher. |
|||
 |
Are more gears better?Basically, gears break up the tool’s power into manageable chunks, preventing too much torque and speed from being delivered at one time. This is useful if you are going to be working with a variety of materials and screw sizes. |
|||
 |
A cordless drill driver with two or more gears will allow you to complete a wider variety of tasks and because you can really fine-tune the amount of power being delivered, there is less risk of a damaged screw or work surface. | |||
 |
However, the more gears a cordless drill driver has, the more expensive it’s likely to be.
If you only want to work with smaller screws and softer materials, then a single gear drill driver should be sufficient. |
