GRINDER: HOW TO CHOOSE THE RIGHT MODEL FOR YOU

 If you have decided to inquire about how to choose a grinder, you are probably planning to buy one. Since we have been selling professional construction machines for many years now, we have often met customers who had no idea of ​​the type of product that best suits their needs, so we decided to also help our online users in the right choice to Buy Online Power tools in Dubai according to the purpose for which it is purchased.

By reading this article it will be clearer how to choose the most suitable grinder for your job. In particular we will see:

What is a grinder and in which cases it is appropriate to use it

• Disc diameter
• Power of the grinder
• The weight and size of the grinders
• Electric or battery-powered grinders
•  See our grinders on offer
• What is a grinder and in which cases it is appropriate to use it.

Without going into various and possible technicalities, at least in this first illustrative phase, we can define a grinder as an electric tool used mainly for:

• Smooth
• Grind
• Cut
• Roughing
• Polish

The uses that can be made of it, as you can see, are truly manifold and the more sophisticated the machines become, the more they allow you to carry out particular and sectorial jobs.

In general, those who buy a grinder do it to cut stone, tiles, wood, marble, granite or to level, polish, eliminate rust, grind surfaces and eliminate burrs produced by welding between metal parts. In some cases these are also used to sharpen the blades of garden tools such as lawnmowers, brush cutters and other work tools.

A first question we ask our customers to recommend the most appropriate product for the job to be done is: which jobs will you do most frequently with this appliance?

This is the starting point from which you cannot ignore if you do not want to risk buying a product and cram it into the cellar the next day. In fact, a first differentiation, in addition to the type of processing to be carried out, must be made on the basis of the materials treated. Each material has a different consistency and therefore needs grinders with different powers and speeds that allow the job to be carried out in the simplest and most precise way possible in complete safety.

In fact, sanding and cutting materials such as wood and plastic require significantly less effort than materials such as iron, marble, tiles, marble and granite which instead put a strain on the grinder.

Technical characteristics and performances

Disc diameter:

the dimensions of the disc must be chosen according to the depth of the cut to be made, considering that higher diameters usually correspond to higher Wattages and therefore higher powers. The classic sizes for grinders are 115mm, 125mm, 230mm, but intermediate sizes have been added over time.

Power of the grinder:

this parameter is generally expressed in W (Watt), higher powers avoid that, under stress, the number of revolutions of the disc decreases and the machine loses its cutting force. Usually the power range of a grinder extends over a range of choices ranging from 600 Watts up to a maximum of 2200 Watts.

In this case, greater power is not always the ideal solution, in fact imagine having to cut a nail with a tool that has an average weight of around 6 / 7kg with a very large diameter disc and a considerable footprint, certainly this choice. unhappy will lead to suboptimal results on different points of view, precision, safety, an excessive effort to hold the machine and therefore to a poor general efficiency.

You will understand well that, as we mentioned earlier, another factor that influences the choice of a grinder is undoubtedly the weight and the relative dimensions.

The weight and size of the grinders:

it is directly proportional to the power of the power tool and to the size of the maximum disc that it can mount. Also from this point of view the choice of a grinder is very broad and in this case the range extends from a minimum of 1.5 / 2 kg to 6/7 kg for larger and more powerful grinders.

The rpm:

this factor indicates the revolutions per minute that the grinder can produce, indicated with revs / min or rpm (from English revolutions per minute or rotations per minute). This is a very important factor for cutting machines like these, and should be chosen according to need because according to the uses you decide to make of them (cutting, grinding, polishing, etc.) you will need different speeds. There are models of grinder with adjustable speed that allow to vary the speed of the tool according to the type of processing to be carried out.

Electric or cordless grinder:

Finally, a detail that should not be underestimated is the choice of the most suitable type of power supply. Also in this case the preferred machine also depends on the type of work to be done and where it is done. Battery grinders will allow you to move with greater agility and use the machine on the go, on the other hand the electric ones, needing to be connected to an electricity source, will therefore be more binding.

 

 Here are some models of grinders that may interest you

 

There are other technical parameters that can help us choose a quality grinder, but in this case we would risk getting too technical and moving away from what was the purpose of our article.

Ultimately, are you a hobbyist and need to do occasional jobs that don't put too much strain on the grinder? In this case you could aim for a small and manageable model, keeping on machines with a maximum diameter between 115 and 125 mm.

Are you a professional and do you use the grinder for professional use? Surely you need more performing models with greater powers that allow higher cutting thicknesses and more intensive and durable performance.
