  "abstract": "An object of the present disclosure is to contribute to determining the wear condition of a fastening unit more accurately. A tool system (1) includes a motor (M1), a fastening unit (24), a control unit (26), a detection unit (27), a rotation stopper (30), and a condition determiner (28). The fastening unit (24) includes: a hammer (244A) caused to rotate with motive power supplied from the motor (M1); and an anvil (244B) arranged forward of the hammer (244A) in a rotational axis direction of the hammer (244A) to receive rotational impact from the hammer (244A). The fastening unit (24) fastens a fastening member by driving a tip tool in rotation. The control unit (26) controls the motor (M1). The detection unit (27) detects a predetermined physical quantity in a state where the hammer (244A) is receiving the motive power. The rotation stopper (30) prohibits the anvil (244B) from rotating. The condition determiner (28) makes determination about the wear condition of the fastening unit (24) based on the predetermined physical quantity detected by the detection unit (27) in a state where the rotation stopper (30) prohibits the anvil (244B) from rotating.",
