3 Tips For Choosing The Right Demolition Hammer

Let’s see together what are the characteristics that allow us to determine what kind of work a demolition hammer is capable of facing.

This article is mainly intended for DIY enthusiasts and novice hobbyists, who still have little experience and therefore are more exposed to the risk of evaluating work equipment based on incorrect parameters. Since power tools are quite expensive, and among these also demolition hammers, before buying one it is good to understand what the requirements are to be paid attention to, and how they affect the level of performance and the intended use of the tool. .

The demolition hammer is nothing more than a more compact, lighter and less powerful variant of the pneumatic one, but far more versatile and suitable for small-scale demolition work.

In the home and hobby, this tool is very useful in construction and renovation works; to remove tiles from walls and floors, for example, to demolish partitions, remove concrete screeds, particularly large and heavy rocks from gardens, drill holes in attics and more.

Depending on the compactness and hardness of the material to be removed, therefore, a certain level of power and the possibility of being able to change the type of tip used are required, so let’s see what are the distinctive characteristics of these power tools.

Power is decisive for the type of work

To choose the best demolition hammer , therefore, you must first understand what type of work you need to use it for; the first and most important requirement, in fact, is that of power.

Unlike drills, saws and other power tools, the power of a demolition hammer is not determined by the number of Watts absorbed by the motor, but by the power in Joule that it is able to impart to the blow. The higher the Joule power, the more effective the tool is in demolishing extremely hard and compact materials, such as reinforced concrete, concrete or rock.

The power in Joules can vary depending on the model and the price range to which it belongs, starting from the cheapest models that develop a force per stroke of about 1 or 2 Joules up to the more expensive ones, which are able to generate up to 26 Joules and more.

If you need to demolish a brick wall, or masonry works made with bricks or with materials of medium hardness, then the hammer does not need to be very powerful, indeed an economic model is the best solution in cases. If, on the other hand, it is necessary to remove a concrete screed, or to tackle medium-sized jobs but on a regular and intensive basis, then it is advisable to focus on a medium-high range model.

The cost can vary a lot in fact, from a minimum of 50 up to 2,500 euros and more, depending on the model; It is clear that in the higher price range there are models intended for intensive professional use, but this does not mean that mid-range demolition hammers cannot be functional also for professional applications.

Overall, therefore, we can say that if the tool is used only for do-it-yourself, when you go to choose the model to buy you have to check the power and stay within a limit that does not exceed 5 Joules per stroke, in this case. the price of the power tool will hardly exceed around 250 euros.

The different standards of the attack

Another determining element is represented by the type of attack possessed by the hammer; the latter, like drills, is equipped with a spindle designed to accommodate the demolition tool. Unlike tires, which only generate the percussion movement, some demolition hammers are able to also give the tip a rotary movement, so the spindle is very similar to that of drills but has a different type of standard, given that the thickness of demolition bits is larger than that of traditional drill bits.

In this case we are talking about the SDS attack, which is available in two variants: original or SDS-Max. Those who are more familiar with power tools will easily understand that the fundamental difference between the two variants is the maximum diameter of the shank that can be inserted. This standard was developed by the well-known German company Bosch, which made four different variants, but demolition hammers only use two.

The SDS attachment, often also referred to as SDS-Plus, was the first original standard and allows you to insert tips whose shank has a diameter between 6 and 10 millimeters maximum; this type of coupling, therefore, is used exclusively on hammers intended for hobby use.

The SDS-Max, on the other hand, allows the insertion of drills with shanks with a diameter of up to 18 millimeters, therefore it is used on heavy medium and high power demolition hammers, therefore intended for professional use. Obviously the latter tend to be more expensive than demolition hammers equipped with the original SDS standard.

The tips, the structural features and the comfort of use

To conclude, it is good to evaluate the versatility of use of the tool and the comfort of use, which largely derives from the structural characteristics of the same. As for the tips, the SDS attachment, both the original and the Max one, allows you to mount different types; however, these are rarely supplied and must be purchased separately. The reason why they are not supplied with accessories, however, as often happens with drills, lies in the fact that not all hammers have the rotary function in addition to the percussive one; and therefore if you intend to use this tool to drill large diameter holes using twist drills, for example, you will have to pay close attention to this detail.

The comfort of use, on the other hand, depends on the noise and vibrations generated by the power tool, which despite being more contained than a pneumatic hammer are still considerable.

If the demolition hammer has to be used for a prolonged time, therefore, this can cause a high stress both to the operator and to the tool itself, compromising its duration. It is good practice, therefore, to make sure that the chosen model is made of good quality materials and well assembled, and to buy ear muffs and padded gloves to wear for prolonged use.
