Embodiments of golf club heads, golf clubs, and methods to manufacture golf club heads and golf clubs are generally described herein. In one example, a golf club head may include a body portion, and an internal mass portion comprising a material having a greater density than a material of the body portion, a height in a top-to-sole direction, a depth in a front-to-back direction, and a width in a toe-to-heel direction. The distance between the internal mass portion and a toe portion edge is substantially less than the distance between the internal mass portion and a heel portion edge. The volume of the internal mass portion increases in a top-to-sole direction, and the height of the internal mass portion is greater than the width of the internal mass portion. Other examples and embodiments may be described and claimed.

A putter is described. The putter includes a composite putter head having a high moment of inertia. The putter also includes a putter head face connected to the composite putter head. The putter further includes a hosel for mounting to a putter shaft. The putter also includes a plurality of sole weights mounted in a sole of the composite putter head.

Some embodiments include club heads having reinforced club head faces. In one example, the club face comprises a reinforcement element such as a looped rib positioned on a rear surface of the club face to provide reinforcement. The club head further comprises an undercut that extends along the entire perimeter of the club face to provide increased club face bending. The combination of the reinforcement element and the undercut reinforces the club head while permitting the club face to bend. Other embodiments of related club heads and methods are also disclosed.

A golf club head that is capable improving on the inertia properties of a golf club head all while also improving the Center of Gravity (CG) location is disclosed herein. More specifically, the golf club head in accordance with the present invention achieves a relative low Moment of Inertia (MOI) about the Z-axis (MOI-Z) as well as a relatively low MOI about the Shaft-axis (MOI-SA).

A cast cup can include a forward portion of a golf club head, including a hosel, forward portions of a crown, sole, heel, and toe, and a face portion or an opening to receive a face insert. A rear ring can be formed separately from the cast cup and coupled to heel and toe portions of the cast cup to form a rigid club head body, such that the club head body defines a hollow interior region, a crown opening, a sole opening, and/or face opening. The cast cup and rear ring can be made of different materials, including various metals, composites, and polymers. Composite crown, sole, and/or face inserts can be coupled to the crown, sole, and/or face openings. Weights can be coupled to the cast cup and to the rear ring. The face can have a complex variable thickness geometry.

Embodiments of golf club heads with components composed of a metal-composite-metal construction are described herein. The metal-composite-metal construction makes up a portion of the golf club head. The metal-composite-metal construction can make up any one or combination of the following structures: faceplate, face insert, internal ribs, turbulators, crown insert, or weight channel. The composite layer of the metal-composite-metal construction is composed of reinforced fibers. The metal-composite-metal construction allows for weight savings in the golf club head while maintaining durability, strength, rigidity, and performance.

Embodiments of golf club heads and methods to manufacture golf club heads are generally described herein. In one example, a golf club head may include a body portion having a front portion, a rear portion, a toe portion, a heel portion, a top portion, a bottom portion, a face portion, and a periphery. The bottom portion may include a forward portion and a rear protrusion at or proximate the rear portion. The rear protrusion may project downward from the periphery and extend longitudinally in a rear-to-front direction. The rear protrusion may include a front-side portion. A toe-side portion may extend rearwardly from the front-side portion towards the rear portion. The rear protrusion may also include a heel-side portion extending rearwardly from the front-side portion towards the rear portion. A weight port may be defined by the rear protrusion. Other examples and embodiments may be described and claimed.

Described herein is a tour iron having a golf club head with a faceplate, a body, and an insert. A sole, top rail, rear, and the faceplate enclose a cavity within the body. The cavity can house the insert. The insert can comprise a low-density material, allowing weight to be concentrated around the peripheral edge of the golf club head. The insert can further comprise multiple materials to improve sound and feel. The rear of the golf club head has an inflection seam running from the heel to the toe. The golf club head has an upper portion, above the inflection seam and a lower portion below the inflection seam. The lower portion can have a depth greater that the upper portion depth. The faceplate, body, and insert can be formed of different materials having different densities. The golf club head has a comparatively high moment of inertia and a low center of gravity. Other embodiments and methods are described herein.

A golf club head is described having a body defining an interior cavity and comprising a heel portion, a toe portion, and a sole portion positioned at a bottom portion of the golf club head, and a crown positioned at a top portion. The body has a forward portion and a rearward portion. A non-metallic striking surface is positioned at the forward portion of the body.

An adjustable interchangeable golf club with a faceplate-based platform to receive components for enhancing and controlling various aspects that control the golf ball flight and spin characteristics. Disclosed are components for adjusting loft and bounce angle, and interchangeable faceplate and rear flange styles. Novel milled surface roughness for enhanced spin control is disclosed along with new milling methods for achieving optimal surface roughness. Lightweight hosel and consequent redistribution of mass in club head greatly increases the inertia of the golf club. Centrally located hosel position aids in club head stability on off-center hits. This results in a golf club that hits the ball higher, straighter, longer, and with increased ball spin characteristics.
