How to choose a punch for home and do not make mistakes ?

Punch - what is it?

Modern hammer is a power tool, characterized by shock-rotational action and is designed to form holes in hard materials (concrete, bricks, etc.).In some cases, it may be used as a jackhammer.That is why the hammer is one of the most popular tools in the construction market.Drilling, shtroblenie holes in the walls, fighting off tiles - effectively and in a short time to perform these works help was he.

Inexperienced inhabitants often confused household hammer and a hammer drill.To avoid mistakes when purchasing advised to examine the fundamental differences between these instruments.Firstly, when the punch impact force is created by electromechanical or pneumatic, and when working with drill - with a mechanical transmission.Obviously in the first case, the drilling force is greater than the second, respectively, more efficient drill operation.

Second, these tools vary drill design.drill chuck does not always guarantee protection against rotation of the drill and not too increases the force of impact at the point of drilling.A kind of "hybrid" of the two instruments can be regarded as a hammer drill, which is also fairly well represented in the sale.So, what to pay attention to choose the best punch for home?

How to choose a punch - study the characteristics

If you're not too experienced in the acquisition of building tools, and the question of how to choose a punch, is quite sharp, it is necessary to pay attention to the following performance items:

• Power.
• rotational speed of the drill.
• impact energy.
• drilling diameter.

speed and quality required drilling holes directly dependent on the power of the product.If your plans include working with excessively hard materials, which need to make large holes, then give preference to a more powerful tool. It should be remembered that the higher the power of the gun, so it will be harder and heavier, respectively, will be more difficult to work with him.As for the speed of the drill, the larger it is, the more convenient to use the punch.Today

available are products, which speed drill is generally 600-1,500 rpm.For large diameter drill speed must be high enough to ensure efficient operation.

When you decide which one to choose punch for home, pay attention to its impact energy.Her figure is one of the most important, as it directly demonstrates the possibilities of the instrument.Impact energy defines the maximum diameter of the holes and the drilling efficiency of breaking the material.Some drills impact energy models can reach 15 joules. With regard to the drilling diameter, as a working figure of domestic punch, the more often its maximum value is specified by the manufacturer in the instructions to the instrument.

Choice punch for home - choose the degree of functionality

Before you make a choice for the gun home, you must focus on the degree of functionality.Do not be seduced too many instrument functions, you may not need.You must be clear about the purposes for which it is acquired.So many drills models have a built-in meter drill hole depth.It allows you to accurately determine whether the drill has reached the desired depth.

Each punch can work in a particular mode, which is equipped with a special switch. It allows you to select mode of the product, thereby controlling the rotational speed of the drill and the working efficiency.For example, when drilling a large hole is recommended to switch to the slow rotation of the drill mode.

If you need to perform a small hole, the speed can be increased by going to a different mode.Unobtrusive and reverse rotation function that allows you to easily pull out the drill bit stuck in the material.After that you will be able to resume their work.
