Types of Hammers and Their Uses

There are many hammers available which are used for different construction and carpentry tasks.

Hammer Types

The most commonly used hammers that are also the least expensive include:

  • Ball Pein Hammers (hickory handle and forged steel head)
  • Mauls (hefty, used for demolition)
  • Claw Hammers (two claw styles, short handle, and rubber grip)
  • Sledgehammers (the most powerful of the group, with a steel handle and forging)

Pound and Claw hammers are designed to pound nails into surfaces. These hammers have a straight claw that includes a flat surface to hold the nail. A round-headed hammer, or riveting hammer, has an oval head that is shaped for tapping. A ratcheting handle speeds up the process, allowing one hand to hold the hammer and one hand to hold the object needing attention.

A Cross peen hammer is designed to tear the surface of a material apart. The head of this hammer (looking like the letter "X") curves upward for the task of dislodging nails.

What is Hammer Material Specification?

Usually most hammers are forged steel with a wooden handle. They can be made from any alloy, but the most common are the chrome-molybdenum and high-speed steels. The head of the hammer may have a single peen or a double peen. Cross-peen hammers have a left-facing and a right-facing peen on either end of the head, which allows very large demolition jobs.

Hammers are also available in a steel-head offset. The head is not straight across and is either 1 or 2 inches wide centrally and a combination of offset and offset. This hammer can be used in close quarter work in tight places.

A handle is also made of a wooden dowel, and a leather thong is usually wound around the thong to make the handle more secure. The handle is of walnut, rosewood, or some other hard wood that will not crack or warp if the hammer is used to drive a chisel. Hammer handles were at one time made of ash, but due to newer manufacturing techniques, they are no longer very common.

The angle of the faces of most hammers is perpendicular, though some are curved less or more. The scarfing of the face occurs when the cutting edges of cold chisels are malleable, and hammering a steel chisel face onto a mallet or another piece of steel will make the cutting edge even more malleable.

What is the Hammer Manufacturing Process?

Companies that specialize in manufacturing tools use the same manufacturing process to create both ball-peen and framing hammers. Most are hand-made by skilled craftsmen and conveyor belts are used only in the final stage of manufacturing.

Step 1: Cutting

First, a piece of steel is cut into the proper size using a water-cooled sawing machine that has a diamond blade.

Step 2: Grinding

The steel bar’s rough edges are then ground smooth using sand-ceramic grinding wheels. Their speed is adjusted depending on the final shape of the hammer the maker is trying to create.

Step 3: The Bending Process

Once the steel is properly shaped, the blacksmith begins the bending process. He begins this process by inserting the steel bar into an automotive-style frame that allows him to bend the steel in any way he likes. In order to fit into the machine, the steel bar is held in a special vise, just like on a car.

Step 4: Completed Frame

The blacksmith then tightens the steel bar until it has assumed the desired shape.

Step 5: Hammerhead Assembly

The hammerhead is connected to the frame by inserting it into a hole in the steel bar.
