Hammer
A simple tool in design, used by man since ancient times. The main property of a hammer is the ability to significantly increase the impact force and apply it accurately.
Hammer is translated into English as Hammer .
To carry out certain work, it is worth using hammers for the appropriate purpose. The right hammer affects not only the speed of work, but also the quality.
A hammer is a dangerous tool, so when working with it you must follow a number of safety rules:
- You shouldn't play with a hammer and fool around. In general, the most serious injuries occur in situations like this;
- Never work with a broken hammer or hammers whose head is not secured and may fall off;
- Never use a hammer that is chipped or cracked.
Sledgehammer
the largest type of hammer. The weight is used to drive concrete posts into the ground
The head of this tool is made of high-strength steel by forging followed by heat treatment in the form of hardening to the required hardness and can be in the shape of a parallelepiped or an ordinary hammer. By the way, the depth of the hardened layer after hardening reaches 30 mm. The handle has a larger diameter and length compared to previous models, which means two-handed operation.
The length of the handle is directly proportional to the weight of the working part of the sledgehammer: the higher it is, the longer the handle and can reach 120 cm, but is usually in the range of 80-90 cm. The cheapest sledgehammers have a wooden handle, but they can also be all-metal.
The hole into which the handle is inserted has a conical shape, and the handle itself is inserted from above and does not need to be wedged. This assembly method completely prevents the massive head part from slipping off. When working with a sledgehammer, you must be extremely careful, because it is considered a dangerous tool. There are several types of sledgehammers, but the most used are the blunt-nosed sledgehammer weighing 2-16 kg, longitudinal or pointed-nosed transverse, which weigh from 3 to 8 kg. The preferred handle option is a rubberized one; it is more expensive than a wooden one, but the tool will be securely held in your hands and dampen vibration during impacts.
Hammer device
The design of the hammer is simple. As a rule, it includes two components: a hammer head (head) and a handle.
Also, depending on the material of the hammer handle, an additional fastening element can be used. For example, for hammers with a wooden handle, wedges are additionally used in the design of the hammer.
The main element in the design of this tool is the hammer head. It comes in a variety of shapes, types and weights. For hammers with metal heads, they are made from special tool steel by forging or die stamping. In this case, the striker part of the head is hardened in water, and the side with the nail puller is hardened in oil. This technology makes it possible during future operation to ensure the strength of the hammer head and the plasticity of the nail puller. At the end, the product is opened with a special varnish to prevent corrosion.
The part of the hammer head that directly strikes is called the striker.
The firing pin can have a variety of shapes - flat, convex or jagged.
The flat shape of the striker is intended for driving (for example, nails). Convex shape - on hammers intended for striking another instrument. With a serrated striker surface - designed to prevent slipping.
In addition, the hammer head can vary in weight.
As for the handle, it can be made of different materials: wood, plastic and metal. The handle affects the ease of use of the hammer. It should be light in weight (relative to the head) and of appropriate length.
Construction store windows show a variety of hammer handles, and it is impossible to single out the most common material for handles.

In conclusion, a few words about safety precautions. As you work, hold the hammer firmly by the end of its handle. Monitor the condition of the tool and do not put your hands near the impact site. Wear gloves and use pliers to hold nails in hard-to-reach areas. Naturally, some will dismiss the basic recommendations, but others will remember a couple of broken fingers and cases of a poorly secured working part flying out.

Handles
In modern models, these hammer parts are made of plastic, polyurethane, and fiberglass materials. However, according to the experience of professionals, a wooden handle is still the best and most popular.
Pegs can be driven into the wood to make the grip on the striker stronger.
In addition, if the handle breaks, you can make it yourself.
Fiberglass is also popular today. It is considered a type of fiberglass. This material contains more than 70% fiberglass. Also contains polyester resins. This material is characterized by very high durability and resistance.
Among the main advantages of fiberglass is strength. It is 9 times higher than that of plastic, and also 4 times higher than that of aluminum. Handles for hammers made from it are not deformed.
Hammer with nail puller

It is worth noting that low-quality hammers of this type are very common on sale. They are cheap in price. They are light in weight and have a poor connection to the head. As a result, they break literally after the second blow or during the first attempt to pull out the nail.
But you shouldn’t overuse the nail puller even with high-quality hammers. They can also break under heavy loads. This applies to pulling out nails larger than 150 mm for ordinary construction (glossy) nails and 100 mm for rough or screw nails.
