Rotary tool base with modular head

A rotary power tool assembly includes a rotary power base and a modular drive head. The rotary power base may be configured to rotate the spindle, and the modular drive head may be configured to be removably coupled to the rotary power base. The modular drive head may include a torque control clutch, a working tip, and torque value indicia. The torque control clutch may be non-adjustably configured to perform a torque limiting slip event in response to the working tip being subjected to torque exceeding a discrete torque value, although the spindle continues to rotate, the torque limiting slip event prevents further rotation of the working tip. The torque value indicia may be externally visible and may include visible features associated with discrete torque values. 一种旋转动力工具组件，包括旋转动力基座和模块化驱动头。旋转动力基座可被构造成使主轴旋转，并且模块化驱动头可被构造成可拆卸地联接到旋转动力基座。模块化驱动头可以包括扭矩控制离合器、工作尖端和扭矩值标记。扭矩控制离合器可以不可调节地构造成响应于工作尖端受到超过离散扭矩值的扭矩而执行扭矩限制滑动事件，尽管主轴继续旋转该扭矩限制滑动事件防止工作尖端进一步旋转。扭矩值标记可以是外部可见的，并且可以包括与离散扭矩值相关联的可见特征。
