What are the different type of head's for golf clubs?
The head for golf clubs sets golf clubs apart from one another. The materials and the design in the club heads affects the control and the distance that the club can generate. Club heads are also designed to maximise the benefits of hitting the ball in the centre of the face, and to minimize the damage from making mis-hits. This allows you to have a more consistent game.
There are different variables for judging club heads. Whether or not they are oversize, the degree of offset, the perimeter weighting and the weight of the sole. Club heads are also made of different materials, and this can affect their performance and feel.
The reason why club heads are oversized is because the sweet spot of the club can become larger. This is important because it means that you have a better chance as a player of hitting the ball in the middle (simply because that middle is bigger). It's all about the sweet spot in golf clubs, and that's what you want to hit. Space age materials have allowed golf club heads to be bigger without them being any heavier than smaller clubs. It's probably also true that your confidence can be helped by standing over a ball looking down at a large club head.
The design of a golf club means that the clubface is set back behind the shaft. This means that when you swing at the ball the face arrives at the ball after the shaft. The aim of this is to ensure that the face of the club is better aligned when it impacts the ball. The degree to which this is the case is called the degree of "offset". Some people like their club heads to be heavily offset, and some people don't. It is a case of personal preference.
Many cast irons are designed so that the weight of the head of the club is distributed around the outside perimeter of the clubface. This is called "Perimeter weighting" and it's purpose is to make it easier to find the sweet spot when you hit the ball and also more likely to increase distance.
The weight of the club head can be distributed more heavily at the sole - or the bottom - of the club. The reason why you may want this to be the case is because it would help you to generate more club head speed. It will also help you get the club underneath the ball, making it more forgiving for mishits. To make it easier to get the ball out of rough or tall grass many clubs will have special grooves or rails.
Club heads can be made out of steel, which is more durable or metal composites, which are lighter.
