Impact tool head

An impact tool head configured to be disposed on a front end of an impact tool, the impact tool head including:

• a rod body extending in an axial direction;
• and
• a flange radially protruding from the rod body, the flange including:
• an inclined flat surface facing toward the front end;
• and
• an outermost peripheral edge connected to the inclined flat surface, and
• a contact position being defined as a position where the inclined flat surface contacts with at least one projection of the impact tool;
• wherein each of the at least one projection is a ball member, as viewed in the axial direction, a ratio of a distance between the contact position and the outermost peripheral edge to a radius of the at least one projection is between 0.1 and 0.6;
• wherein a projection length of the inclined flat surface on the axial direction is defined as a first length, and in the axial direction the outermost peripheral edge has a second length smaller than the first length.
