DW: Hammer and mallets

Page history last edited by Joel Rosenberg 10 years, 1 month ago

 

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.

 

Safety

 

WEAR EYE PROTECTION AND WATCH THE FINGERS. BEFORE USING, CHECK FOR A LOOSE HEAD OR A CRACKED HANDLE. DO NOT USE HANDLE AS A PRY BAR, OR TO KNOCK SHARP EDGES TOGETHER.
