BALL PEEN HAMMER.— The ball peen hammer is sometimes referred to as a machinist’s hammer. It is a hard-faced hammer made of forged tool steel. See figure 13-1.

Figure 13-1 .—Hammers.

The flat end of the head is called the face. This end is used for most hammering jobs. The domed end of the hammer is called the peen. The peen end is smaller in diameter than the face, and is useful for striking in areas that are too small for the face to enter. Ball peen hammers are made in different weights, usually 4, 6, 8, and 12 ounces and 1, 1 1/2, and 2 pounds. For most work, a 1 1/2-pound and a 12-ounce hammer will suffice.

MALLETS.— A mallet is a soft-faced hammer. Mallets are constructed with heads made of brass, lead, tightly rolled strips of rawhide, plastic, or plastic with a lead core for added weight.

A plastic mallet, similar to the one shown in figure 13-1, is the type normally found in the AM’s toolbox. The weight of the plastic head may range from a few ounces to a few pounds; however, the size of the plastic mallet is measured across the diameter of the face. The plastic mallet may be used for straightening thin sheet ducting or for installing clamps.
