The first electric hammer drill appeared in 1932, despite the fact that its progenitor was created back in 1851. But that's not the point, just rotary hammers have recently become a very common type of tool. Almost every family has this, because it is an indispensable assistant in carrying out any type of repair. But in order for it to be ready for work at any time, it is necessary to take care of the selection of components for it in advance. Now we'll talk about how to choose the right drill for a perforator.
At the present time, only three types of such components are distributed. These are SDS+ and SDS Max drill bits, as well as the brand new and therefore less popular SDS-top. Although it should be noted in advance that the developers consider this particular drill to be optimal for creating holes up to 25 mm. As for the first two options, they mainly differ in their fastener design and their maximum diameter. The point is that SDS+- these are drills for perforators with a total weight of up to five kilograms. But SDS Max are already designed for heavy tools.
By the way, if you wish, you can find special adapters and use SDS Max on light equipment, and SDS+, on the contrary, on heavy equipment. However, this cannot lead to anything good. In the first case, the wear of the perforator will increase, and in the second, the wear of the drill. Both options are not so good.
If you choose a drill for a perforator, then first of all you should pay attention to its removal of sludge. At the moment, according to this criterion, drills can be divided into three types: with a small angle of inclination, with a large angle of inclination and auger. The most optimal is the last outlet - auger. The fact is that it is able to provide the fastest removal of cuttings, which is especially useful when drilling deep holes. However, care must be taken to ensure that deep grooving is used.
Now let's touch on the economic side of the issue. The cheapest drill for a perforator will be if a Chinese or domestic company is listed as its manufacturer. But, buying such products, you need to count in advance on its fragility. In addition, cheap drills are not always made in accordance with all standards. However, some exceptions can be counted on. It is likely that such a drill will serve you for a year. But these are precisely the exceptions that you should not really hope for.
Still the bestthe solution would be to use products from the second price category - these are drills from well-known manufacturers “for an amateur”. Their use is almost ideal at home.
However, there is also a third price category. These are professional drills. They will serve for a really long time, while their technical characteristics will necessarily be at the highest level. However, the purchase of such a product will have to allocate a significant part of the funds.
Having taken into account the above information, it is already possible to confidently go to the store and choose the most suitable drill for the rotary hammer.
