Title: ROTARY IMPACT TOOL
Abstract:
A setting unit (15) sets a number of impacts for shutoff of an impact mechanism (9). An impact detection unit (12) detects the impacts applied to an anvil (7) by the impact mechanism (9). A control unit (10) counts the number of impacts detected by the impact detection unit (12) and stops the rotation of a motor when the counted number of impacts reaches the number of impacts for shutoff. A rotation angle acquisition unit (19) acquires the anvil rotation angle due to one impact of the impact mechanism (9). The control unit (10) corrects the number of impacts for shutoff set by the setting unit (15), on the basis of the number of impacts when the anvil rotation angle acquired by the rotation angle acquisition unit (19) has reached a prescribed threshold value or is less than the prescribed threshold value.
