Today we will discuss about types of hammers. Hammer is
widely used in mechanical industries to drive any thin metal part like nails
etc. by an impact force. It is a tool which is used to create a sudden pointed
force, which is further used to drive nails, remove unwanted metal parts form
work piece and also in forging to create flat surfaces. Hammers are also used

A hammer consist two main parts. The first one is handle and
the other one is head which is a heavy metal piece mounted at perpendicular to
the axis of the handle. There are many different types of hammers used in

9. Rock climbing hammer:
It is a special type of hammer used to climb the rocks.
10. Rounding hammer:
It is also known as blacksmith hammer. It has round face
which is used to design or shapes a forged bar or sheet in blacksmith.
11. Soft faced hammer:
It has a soft face of rubber, plastic or copper. It is used
where steel face may damage workpiece.
12. Stonemason’s hammer:
This hammer is also known as brick hammer. One end of the
head is flat and other end has a chisel like shape. It is used to split bricks
or concrete wall.
13. Welder chipping hammer:
13. Welder chipping hammer:
This hammer is used to remove unwanted welded area form the work
piece. It is also dissipates heat.
14. Lump hammer:
It is a double face hammer and used to driving steel chisel
in work piece. It is one of the types of sledge hammer which has smaller handle
with light weight. It is mostly used in domestic work.
15. Mechanic's hammer:
It is used to remove dents form the sheets. It has a small
curve anvil at one side of head and a sharp chisel type face at other side.

material. In this hammer the hammer head is attached to a piston which driven
by the steam pressure. At the piston moves down it provide impact force which
used to shape the material.

mechanical. It is used to dig out roads.
