Impact drivers are power tools mainly used to drive screws and tighten nuts. 它们的外观和功能可能与钻头相似, 但这两种工具之间存在一些关键区别. The primary distinction is that impact drivers provide more torque or twisting power than standard power drills. This makes them the better choice for larger-scale projects involving more intense fastening tasks, 比如房屋建设或改造.

然而, impact drivers don’t feature a chuck to accept a variety of drill bits. Instead, they use a hex collet that only takes bits with a 1/4 inch hexagonal shank. These bits are designed to withstand the increased force exerted by the impact driver. An impact driver is great for driving larger screws and fasteners without stripping them.

Impact drivers are also smaller and more lightweight than traditional 钻机司机s, so you can easily use one around the house or take it with you to and from job sites. 这不仅使它更容易处理, but the additional power of an impact driver does most of the twisting work for you, 尽量减少手腕的压力.

什么时候应该使用撞击驱动?
除了处理更大的项目, an impact driver is the preferable option when you want to drive fasteners more quickly. 一个标准的 钻机司机 更好的全能工具是因为它的多功能性吗, as its chuck can accept a range of different bits based on your needs. Impact drivers can handle some of the same drilling tasks as a power drill, 虽然通常不会达到同样的精确度. They should be reserved for applications where extra torque is needed, 比如钻穿金属或密实的木头.

如何选择冲击驱动程序
There are a few important features to consider when picking the impact driver that’s best for you.

电压
You can find impact drivers in a range of voltages including 12V, 18V, and 20V. Higher voltage levels offer more torque, but these tools are generally larger and bulkier. 在一般情况下, the difference in power between an impact driver on the lower end and higher end of the voltage spectrum may be negligible enough that you’ll want to go with the smaller tool for its convenience and portability.

无刷电机
和标准钻头一样, impact drivers with brushless motors also come with various advantages. 无刷电机运行效率更高, 减少过热的风险, 并且会延长工具的使用寿命.

RPM
Many impact drivers include multiple speed settings that you can adjust depending on the job. 你可能会找到一个设置为0-850的, 0-2100, 和0-3000 RPM轻到更重的任务. 然而, you’ll likely prefer an impact driver with a variable speed function that gives you more control over the precise RPM setting rather than sticking you with just three or four range options.
