Golf club head

A set of golf club heads comprising:

• a first golf club head comprising:
• a first loft between 30 degrees and 54 degrees;
• and
• a first main body including:
• a first top portion;
• a first sole portion opposite the first top portion;
• a first heel portion;
• a first toe portion opposite the first heel portion;
• and
• a first hosel portion extending from the first heel portion and including:
• a first hosel bore with a first open end for receiving a golf club shaft and a first abutment surface configured to support the golf club shaft;
• and
• a first auxiliary recess extending sole-ward from the abutment surface, the first auxiliary recess comprising a volume greater than 2.25 cubic centimeters;
• a second golf club head comprising:
• a second loft less than 30 degrees;
• and
• a second main body including:
• a second top portion;
• a second sole portion opposite the second top portion;
• a second heel portion;
• a second toe portion opposite the second heel portion;
• and
• a second hosel portion extending from the second heel portion and including:
• a second hosel bore with a second open end for receiving a golf club shaft and a second abutment surface configured to support the golf club shaft;
• and
• a second auxiliary recess extending sole-ward from the abutment surface, the second auxiliary recess comprising a volume less than 1 cubic centimeter.

A method of forming a correlated set of golf club heads comprising:

• providing a first golf club head having a first striking face and a first hosel portion including a first hosel bore with a first open end for receiving a golf club shaft and a first abutment surface configured to support the golf club shaft, and an auxiliary recess extending sole-ward from the abutment surface, the auxiliary recess comprising a volume greater than 2.25 cubic centimeters;
• applying a coating to at least the first striking face of the first golf club head;
• applying a first media blast to the first striking face, the first media blast comprising aluminum oxide having a grit between 180 to 120;
• providing a second golf club head having a second striking face and a second hosel portion including a second hosel bore with a second open end for receiving a golf club shaft and a second abutment surface configured to support the golf club shaft, and a secondary bore extending sole-ward from the abutment surface, the secondary bore comprising a volume less than 1 cubic centimeter;
• applying the coating to at least the second striking face of the second golf club head;
• and
• applying a second media blast to the second striking face, the second media blast comprising a mix of aluminum oxide and a ceramic media, the aluminum oxide having a grit between 180 and 120.
