1. Different voltages:
One is 12v voltage, the other is 16.8v voltage;
2. The number of revolutions is different:
The motors used under different voltages are different, and the higher the voltage, the larger the number of revolutions;
3. Differences in battery capacity:
Motors with different voltages require higher electronic capacity relative to the configuration required.
working principle:
The DC motor rotates, and after being decelerated by the planetary deceleration mechanism, it drives the drill chuck to rotate to drive the batch head or drill bit. By pulling the levers of the forward and reverse switches, the polarity of the DC power supply can be adjusted to change the forward or reverse rotation of the motor to achieve disassembly and assembly operations.
Lithium drill use:
1. It is used for screwing in and out of screws, wood screws, self-tapping screws, etc. It can also be used for drilling various metals and woods.
2. According to the voltage of the rechargeable battery block, there are 7.2V, 9.6V, 12V, 14.4V, 18V and other series.
3. According to the battery classification, it can be divided into lithium battery and nickel-chromium battery. Lithium battery is lighter and has lower battery loss, and the price is higher than that of nickel-chromium battery.
