Brass Hammer with Carbide Coated Distal End

Products such as hammers or chippers used to reduce sizes of materials are subject to continued wear. Another example is found in the teeth of hammers located at the distal end used for removing nails. Commonly brass hammers are used in industry so as to not damage the material that it is used to strike against due to the softness of brass. The high cost of tools and short life spans of non-wear resistant materials is a major concern in the construction industry. Any advance which can increase the life of wear parts reduces enormous losses and cost of replacement parts, cost of the replacement process, and loss of productive use of the equipment during the replacement, in addition to inventorying and shipping costs.

How to produce a brass hammer with a wear resistant distal end?

Conventional brass hammers having brass teeth used to pulled steel nails (much harder than the brass) will wear out very quickly and become deformed and useless. Due to the high cost of forging mixed metal tools a normal hammer capable of removing nails must also be used along with the soft brass hammer for damage control. What is needed is to produce a brass hammer with a wear resistant distal end.

The present invention is a brass hammer with a carbide coated distal end used for pulling nails in a wear resistant manner retaining the shape and formation of the teeth for many uses over an extended lifetime.

Hammer 100 built having distal end 110 with protruding teeth 120 has a carbide coating

130 applied over teeth 120 by means of CVD, PVD plasma spray or hot dipping mechanisms (not shown). Proximal end 160 is not coated with carbide coating 130 as to retain the brass finish for soft striking of surfaces (not shown). Carbide coating 130 , atop teeth 120, allow the user to remove nails (not shown) without wearing or disfiguring distal end 110 thereby increasing the lifespan of hammer 100 .
