• More of a mechanic's and blacksmith's tool but now and again they found use in other trades. The peen is the part behind the hammer head and is used for riveting and curving metal. If you take a flat piece of metal and strike it with a ball peen then a small dimple will appear on the surface. The surface at that point has slightly expanded.
• In its center, a slot is cut, with whose help nails, etc. Can be easily extracted (taken out). This hammer generally used by the carpenters in the carpentry trade. It has been shown in the figure. If compared to as a drilling hammer or lump hammer, the tool has a small, double-faced head that is similar to a sledgehammer.

A ball-peen or ball peinhammer, also known as a machinist's hammer,^[1] is a type of peeninghammer used in metalworking. It has two heads, one flat and the other, called the peen, rounded. It is distinguished from a cross-peen hammer, diagonal-peen hammer, point-peen hammer, or chisel-peen hammer by having a hemispherical peen.

Uses[edit]

The hard-face hammer is made of very forged steel. The best general purpose machinist's hammer is the ball-peen hammer. The lat end of the bead is called the face. This end is used for most of the hamstring jobs you will have. Also The another end of the hammer is called the peen.

Besides for peening (surface hardening by impact), the ball-peen hammer is useful for many tasks, such as striking punches and chisels (usually performed with the flat face of the hammer). The peening face is useful for rounding off edges of metal pins and fasteners, such as rivets. The ball face of the hammer can also be used to make gaskets for mating surfaces. A suitable gasket material is held over the surface where a corresponding gasket is desired, and the operator will lightly tap around the edges of the mating surface to perforate the gasket material.^[2]

Variants[edit]

Variants include the straight-peen, diagonal-peen, and cross-peen hammer. These hammers have a wedge-shaped head instead of a ball-shaped head. This wedge shape spreads the metal perpendicular to the edge of the head. The straight-peen hammer has the wedge oriented parallel to the hammer's handle, while the cross-peen hammer's wedge is oriented perpendicular. The diagonal-peen hammer's head, as the name implies, is at a 45° angle from the handle. They are commonly used by blacksmiths during the forging process to deliver blows for forging or to strike other forging tools.

Head materials[edit]

Ball-peen hammer heads are typically made of heat treatedforgedhigh-carbon steel^[3] or alloy steel; it is harder than the face of a claw hammer.^[4] Softer brass heads are sometimes used.
