Hammers and mallets
Hammers and mallets are used to apply a striking force.
The carpenter’s hammer is used for driving and pulling nails and tapping wood chisels. |
Machinist’s ball peen hammers have a flat striking face for striking punches and chisels, and the other end is for forming soft metal, peening rivet heads, and striking metal in out-of-the-way plac |
The dead blow hammer is a shot-filled, rubber encased, single-piece hammer. It allows for greater striking power, and the elimination of broken heads and splintered handles. |
Sledge hammers have heavier heads and longer handles, and are used for striking punches and chisels, for breaking stones and concrete, and for setting timbers. |
The rubber mallet has a cylindrical rubber head. It is used for forming sheet metal, driving dowels, and small stakes. |

How to use
- The proper way to hold any hammer is near the end of the handle.
- TIP: Attach tape to handle to show students where to grip.
- Strike nail or tool squarely and on center to prevent the hammer from glancing off.
- Small nails require light blows almost entirely from a wrist motion. Heavy blows come from the wrist, forearm and shoulder.
