Hammers
Ball peen hammers,
also known
as machinist’s hammers, are used for
metalwork.
The flat surface on the head is
called the face. The rounded portion
at the opposite end is called the peen.
You can form thin metal by applying light, steady blows with the peen of the
hammer. You use a light touch because the head can damage materials made of
softer metal.
Use a
soft-faced hammer
when
you want to protect the surface
you’re working on. Its replaceable
faces are made of materials such as
soft lead, plastic, wood or rubber that
won’t damage a metal surface.
Using
a
dead
blow
hammer
will also protect a metal surface. Its
head is Flled with shot and coated
in rubber. That helps give it greater
striking power and reduces noise,
vibration and bounce-back.
Save
the
sledge
hammer
for
heavy-duty work. Its head is made of
forged steel and may weigh from 2 to
20 pounds.
