DIFFERENCE BETWEEN IMPACT DRILL AND TASSELLATORE

There are different types of electric tools for drilling and in this article I will illustrate in 5 simple steps:

what is a hammer drill (or hammer),

what is a tiller and their main differences,

Let's briefly see the main characteristics of a hammer drill (or hammer) and a hammer drill.

 

a) Hammer drill (or hammer drill)

 

To the normal drilling function given by the rotation of the spindle it combines the "hammer" or percussion function, obtained by the rotation of 2 discs or splined gears which alternately overlap each other, also generating an alternating linear motion of the tip.

The percussion effect is, therefore, obtained from the physical contact of different parts through the imposition of a pure mechanical motion.

 

b) Hammer

 

The alternating linear motion of the tip is achieved through an electro-pneumatic actuator which in the chamber inside the tool body compresses the air above the piston itself.

Air is the vector for the transmission of motion to the tip; in this case there is no direct contact between the implementing body and the implemented one.

But let's get to the 5 main differences between a hammer drill (or hammer) and a hammer drill.

 

1) Flexibility

 

A hammer drill has a selector, often a simple plastic knob, which can be turned to only two positions: drilling or hammering; the 2 modes are highlighted by universal symbols, a drill bit for the first and a hammer for the second.

The impact drill is designed for drilling different materials, such as wood, metals (simple drilling function) and concrete (percussion) as needed.

The hammer, on the other hand, was created to drill only concrete, stone, bricks and inert materials in general.

 

2) Power

 

It is not really correct to use this term for comparison.

In fact, with power we usually mean the rated Watts, therefore the consumption of the electric tool: it should be borne in mind that the efficiency of the system is about 50%, therefore, if a drill has 1000 W as a plate, the power actually developed will be half.

For a comparison between a hammer drill and a hammer drill, it is good practice to refer to the energy developed by the power tool, expressed in Joules.

A hammer develops values ​​between 3 and 5 J on average, while a hammer drill up to 2 J.

This means that drilling concrete with a hammer drill is more difficult than the hammer because the missing energy gap must be bridged by the user by pushing with greater force, and consequently causing greater fatigue of the limbs that support the electric tool.

 

3) Type of chuck and tips

The hammer drill has a spindle that houses drills with a cylindrical shank, which are the classic bits for drilling.

You can see an example of cylindrical shank drills for metal at this link.

The chuck can be locked with a key, where the tightening is carried out with a special toothed tool, or self-locking, a technology that now represents the state of the art.

All the self-tightening chucks of Ferramenta Paride are at this link.

However, if the latter type is mainly used as a firing pin, it tends to cause greater wear either of the shank of the tips or of the jaws of the mandrel, depending on the hardness of the materials in contact and the heat treatments used on them ( carburizing or surface hardening).

In fact, since the clamping force is not very high, it can generate a rotation of the tip with respect to the jaws during use, which can be literally turned and consequently ruined.

The hammer, on the other hand, houses bits with quick coupling, called SDS-plus or SDS-max that are locked in place with a simple click of the spindle.

Therefore, in the hammer, it is absolutely not possible to mount drilling bits other than those for concrete with quick coupling, but on the other hand, you can use accessories such as pointed chisels or planes for removing glue and tiles.

In general, concrete drilling drills have a specific helical shape and a much smaller cutting edge angle than metal drills.

In addition, if of good quality, they are easily recognizable by the addition of a diamond "insert" on the head which increases their hardness.

 

4) Weight and handling

 

It can be seen that for the same nominal power (W) a hammer is heavier than a normal hammer drill, precisely because of the greater strength of the components inside.

However, all major manufacturers are focusing on improving handling and e

ergonomics, to ensure a less tiring use of the instrument.

The advice, therefore, is to not only evaluate different brands based on the weight indicated in the catalog, but literally "take in hand" the hammer drill or the desired hammer to evaluate the handling, simulating the position of normal use and looking for to understand the strain generated on the arms and shoulders.

 

5) Price

 

Often the first aspect considered, but in this analysis I wanted to leave it purposely in the last position.

The price of a hammer drill is, for the same brand, generally higher than a hammer drill; this is because the first electric tool is addressed to a more specific use and, therefore, has a more complex and refined mechanics, as well as robust.

 

Conclusions

 

In conclusion, to evaluate which tool to choose, it is good to have an idea of ​​what the required use is and for how long concrete, or similar material, must be drilled.

If during your work you deal more with brick drilling then having a specific tool such as a hammer will allow you to take full advantage of its specifications and its resilience for this type of material.

The mechanical percussion system will not be heavily strained as it would be in the case of using a hammer drill; in addition, the user's body will not be too tired.

On the other hand, however, if your work always confronts you with different materials, such as metals and wood, but also sporadically concrete, then a hammer or impact drill will allow considerable flexibility within the same machine.

As for the price, my advice is to use this indicator as the last yardstick only when all the previous 4 points have been carefully evaluated.

It makes no sense to make a wrong choice just to save a few tens of euros for the benefit of a hammer drill, when in reality the application would require a hammer.

 

Finally, I leave you with one last piece of advice: when carrying out any work, be it professional or domestic, especially in the field of electrical tools, the phrase "who spends more, spends less" is a postulate that does not require demonstration.

In fact, there is nothing more frustrating than spending more energy than necessary because the tools available are not adequate or break during use!

Try to carefully evaluate the value for money as spending little does not mean you have made the deal of the week; spending little means receiving something of a quality proportionate to the amount invested.

There is nothing strange, in fact, that mechanical parts can wear out over time, as happens in cars, but generally with simple interventions you can go back to using your hammer drill or hammer for many years to come!
