Punch battery - its advantages and disadvantages

Cordless rotary hammer electromechanical action

It is this type of tools make mobile, and for good reason - the cartridge movement, as we know, punch reciprocates, and if it is done through an electromagnetic coil mounted on the striker, it passes almost withoutfriction.As a result, energy consumption required for this movement is small, however, and the corresponding performance.The batteries used are different: lithium-ion, nickel-cadmium and finally NiMH.

How long enough battery life depends on many factors, not the least of its condition.Also plays a role of a material in which punching is carried out, and the depth of the holes, respectively, their diameter. On average, recess 10 centimeters deep concrete during a storm-section 12 mm takes about 8.5 seconds .With the new battery such holes can be about 100, so the total time at maximum load (continuous) is about 15 minutes.

cumulative punch, which is not desirable to be confused with the battery

Sounds like it seems, but the principle of action of the perforation completely different, based on the explosive charges set out in the special housings or metal tape.Uses such drills for opening the oil or gas bearing strata deep wells, for a more active and efficient development of natural resources.The only thing there is a similarity with battery - charges used to detonate an electrical impulse.

for construction works of this type equipment is used for the simple reason that even a microscopic explosion inside the concrete slab or brick can not be controlled, and hence the consequences quite unpredictable.Especially as to lay the case or cumulative tape perforator should be drilled deeper hole than to cope with the usual metallic drill.

Advantages and disadvantages of autonomous drills

main advantage that it is clear and without words - is, of course, a power supply, the absence of which prevents the use of powerful networking drills.For the sake of such a factor can be a little sacrifice power.

downside - if you can not then charged battery, the charge has to spend very carefully, and that it does not suffice for a long time, up to 3 hours at the most measured and leisurely work.Everything rests on the number of holes, if you need to do 30-40, the battery capacity will still not completely devastated.

Accumulator perforator charging a little more than half an hour, the optimal time off in the presence of nearby power source.

Yet a number of disadvantages - high noise accompanying perforating and hefty weight.Unfortunately, the principle of the electromechanical not without excessive noise, while as pneumatic hammers (only network nodes due to increased friction) are much quieter.

tool weight increases due to the battery, the capacity of which sometimes reaches 108 W / h, which affects the size and, consequently, a lot of toppings battery.Unfortunately, the deficiencies in the reporting tool more than the advantages, and its only advantage - autonomy.
