Golf club heads and methods to manufacture golf club heads

A golf club head comprising:

• a body portion having toe portion, a heel portion, a front portion, a rear portion, a top portion, a sole portion, a hosel bore at the heel portion, and an interior cavity;
• a filler material partially or entirely filling the interior cavity;
• and
• a hosel portion coupled to the hosel bore, the hosel portion having a serpentine shape and configured to couple with a golf shaft,
• wherein the hosel bore and the hosel portion are disposed within a space bounded by a center longitudinal plane, a heel boundary plane, a front boundary plane, and a lateral plane parallel to the front boundary plane and separated from the front boundary plane by a distance equal to one third of a total length of the golf club head in a front-to-rear direction,
• wherein the hosel bore and the hosel portion are intersected by a heel dividing plane parallel to and equidistant from the center longitudinal plane and the heel boundary plane,
• wherein the hosel portion is configured to orient a shaft axis toe-ward relative to a center of gravity (CG) location of the golf club head,
• wherein a distance between the shaft axis and the CG location in a heel-to-toe direction is greater than or equal to 5 mm and less than or equal to 6 mm,
• wherein a distance between the shaft axis and the CG location in a front-to-rear direction is greater than or equal to 0 mm and less than or equal to 3 mm, and
• wherein a distance between the shaft axis and the CG location in a top-to-sole direction is greater than or equal to 0 mm and less than or equal to 3 mm.

A golf club head comprising:

• a body portion having toe portion, a heel portion, a front portion, a face portion at the front portion, a rear portion, a top portion, a sole portion, a hosel bore at the heel portion, and an interior cavity;
• an alignment aid;
• a filler material partially or entirely filling the interior cavity;
• and
• a hosel portion coupled to the hosel bore,
• wherein the hosel bore and the hosel portion are disposed within a space bounded by a center longitudinal plane, a heel boundary plane, a front boundary plane, and a lateral plane parallel to the front boundary plane and separated from the front boundary plane by a distance equal to one third of a total length of the golf club head in a front-to-rear direction,
• wherein the hosel bore and the hosel portion are intersected by a heel dividing plane parallel to and equidistant from the center longitudinal plane and the heel boundary plane,
• wherein the hosel portion provides an unobstructed view of the alignment aid at an address position, and
• wherein the hosel portion is configured to orient a shaft axis toe-ward relative to a center of gravity (CG) location of the golf club head.
