Why The Screwdriver Scrolls Under Load

Conversion of a screwdriver from battery to mains supply
If your cordless screwdriver is out of order, it is not necessary to look for a new battery for it. You just need to convert it to network! Step by step instructions in our material.

Battery Disadvantages

Needs regular recharging. Sooner or later, batteries will use up their cycle life.
The cheaper the tool, the faster the rework time will come.

There is nothing wrong with that, but you should be aware that the manufacturer saves as much as you do. Consequently, the most expensive unit (namely the battery) will be the cheapest when bundled.

As a result, we get an excellent tool with a serviceable motor and not a worn gearbox, which does not work due to a poor-quality battery.

There is an option to purchase a new set of batteries, or replace faulty batteries in the unit. However, this is a budget event. The cost is comparable to buying a new screwdriver.

The second option is to use a spare or old battery from the car (if you have one). But the starter battery is heavy, and using such a tandem is not very comfortable.

DIY screwdriver alteration

Consider the option with an external power supply.

AC adapter for screwdriver in battery housing

If your tool is not too powerful, you can place the power supply in a handle or case from damaged batteries.

External power supply

The idea is not as absurd as it might seem. Even a large and heavy buck rectifier can just stand near the outlet.

You are equally tied to the power supply, and to the stuck mains plug. And the low-voltage cord can be made of any length.

IMPORTANT! Ohm’s law says. With the same power, decreasing the voltage. We increase the current! Accordingly, the 12-19 volt supply cord should have a larger cross section than 220 volts.

Battery case power supply

Mobility remains, you are limited only by the length of the network cable. The only problem is how to squeeze a sufficiently powerful transformer into a small case.

We recall Ohm’s law again, and understand that a powerful 220 volt electric motor can be compact.

We build in a ready-made power supply

To do this, you need to purchase a ready-made block with suitable characteristics and dimensions. There is enough of this kind of stuff on the radio markets.

Take the body with you and go to the fitting. When the required power source is purchased, we carefully separate it from the case.

We place the screwdriver in the battery box. All components must be securely fastened.

If necessary, extend the wires between the control board and the transformer. If the circuit touches the metal parts of the transformer during operation, a short circuit will occur.

Since the space in the case allows. Separate the board and the transformer for better cooling. Whichever quality power supply you choose, the load will be high and overheating is possible.

It will not be superfluous to fix additional radiators on the power control microcircuits. Operate the screwdriver for a long time, disconnect it from the mains and touch the radio components on the control board.

You yourself will understand which elements need heat dissipation. Holes for air circulation can be made in the housing.

Redesigning the power supply unit with your own hands will not take much time, and the cost of the purchased module is incomparable with restoring the battery’s performance.

Using a car battery charger

The principle is the same as using a computer power supply. It is necessary to purchase an old charger for the starter batteries. The modern fashion for compact impulse chargers has left analog linear devices with manual control of voltage and charge current behind. Therefore, such a device can be purchased on the automotive market for a symbolic cost.

Charger MAX INTER

It’s good if the voltage can be adjusted smoothly. In this case, your makeshift power supply will fit any screwdriver.

Converting it to a power tool is reduced to connecting the input of the electric motor to the power terminals of the charger.

Those who have used a cordless screwdriver have appreciated its convenience. At any time, without getting tangled in the wires, you can crawl into hard-to-reach niches. Until the battery runs out.

Ice screw driver. Which one to choose in 2020?

Hello! Do you love ice fishing but tired of manually drilling holes? A cordless screwdriver can make your life easier. You can easily fix an ice screw into it and drill 100-150 holes with one charge, depending on the thickness of the ice. True, not every model is suitable for this job. What characteristics a screwdriver should have in order to confidently cope with drilling will be discussed in this article. Read it to the end, as below will be presented specific high-quality models that can withstand the required load, but have the lowest price. This article is regularly updated, so it is always up to date.

I work as a sales assistant for power tools, so I am well versed in the range. In addition, I myself sometimes go on a winter fishing trip, so I can imagine the conditions in which a screwdriver will have to work. In general, having estimated these conditions, tested some models and talked with other fishermen, I figured out which screwdriver to choose for an ice auger so that he could handle this business with honor. Let’s start describing the required characteristics.

Heavy Duty Performance

Agree that the rotation of the drill in ice requires quite a lot of effort from the screwdriver. My tests have shown that a unit with a torque of at least 60 Nm can cope with such work. The same figure is confirmed by other fishermen who are already drilling holes with a screwdriver. Therefore, when buying, you need to build on this value.

But in this place we must make the following reservation: not all screwdrivers, which will have a torque of over 60 Nm, will suit us. Among them there are those in which a large torque is achieved due to the impact mechanism. It is good for tightening nuts and bolts, but absolutely useless when drilling ice. Therefore, for ice fishing, models that achieve high torque due to impact are not suitable.

Heavy loads also require the screwdriver to be of a professional grade, since only then can it last a long time. Professional tools are made by the following manufacturers:

AEG
Bosch (blue)
DeWalt
Makita
Metabo

The household class will not work, therefore we do not consider all sorts of bison, calibers, encores and other Chinese.

If you have drilled by hand before, you may remember how you sometimes got jammed during this process. Now imagine what would happen if wedging occurs while drilling with a screwdriver. Your hands can easily be twisted. To protect yourself from this, it is necessary that the screwdriver has an additional handle in the kit, which is installed on the back of the main one. This way you can confidently hold the device by grasping it from both sides. This will keep your hands intact.

Let’s summarize this part like this: a large load requires a professional shockless screwdriver with a torque of 60 Nm. And for convenience and safety, an additional handle is also needed in the kit. With the factor of heavy load sorted out, let’s move on to the need for long-term work without recharging.

Characteristics for working in cold conditions

This point is closely related to the previous one, since it is again about the battery capacity, which becomes less at low temperatures. Therefore, this condition again requires the purchase of a screwdriver with a large-capacity battery.

Also at this point it should be said about the types of batteries. There are three of them:

Lithium ion
Nickel-cadmium
Nickel metal hydride

It is believed that nickel-cadmium and nickel-metal hydride batteries do better than lithium-ion batteries in the cold. However, my tests show that modern lithium-ion batteries do well in freezing temperatures as well.

But even if it turns out that your lithium-ion batteries refuse to work in a cold state, they can simply be kept warm. “And where to get heat on winter fishing?”. You ask. And I will answer: you yourself are the source of heat. Make additional internal pockets for batteries in your jacket, sheepskin coat (or whatever you go fishing in). Lithium-ion batteries are lightweight, so keeping them there is convenient. When you need to drill the next hole, you take out the battery. When you sit down to fish, you clean up.

And the next point on this point is that nickel-cadmium batteries have a capacity of no more than 2 Ah, and nickel-metal hydride batteries no more than 2.5 Ah. Lithium-ion ones can also have 5 Ah. Proceeding from the fact that we need to have more than 3 Ah, we discard the nickel-cadmium and nickel-metal hydride types aside, especially since they gradually cease to be produced as obsolete.

So, having considered the three main factors that will affect the operation of the screwdriver in winter fishing conditions, we found out that we need a professional non-impact screwdriver with a torque of at least 60 Nm, lithium-ion batteries from 3 Ah and an additional handle in the kit.

Which models meet these requirements?

Features for long battery life

On the pond, no one will let you down, so the operating time of the screwdriver will depend on the amount of the stored charge. The charge reserve is equal to the battery capacity and is measured in ampere-hours. I think you understand that for drilling ice on winter fishing it is better to purchase a screwdriver with an increased battery capacity, which is at least 3 Ah. And you need to have at least two of them. Although, as I already wrote, we need a professional-grade device, and they are always equipped with at least two batteries.

By purchasing a screwdriver with a 3 Ah battery, you can drill at least 100 holes, and if at 5 Ah, then 150-170. Although this indicator, as mentioned above, also depends on the thickness of the ice.

Thus, when buying, we give preference to devices with the most capacious batteries. Now is the time to move on to such a factor as cold.

Required characteristics of a screwdriver for work on ice fishing

Think and imagine what difficulties you will face when operating a screwdriver on a frozen water body? After a little evaluation, three factors come to mind:

Huge pressure
Long battery life
Cold

To work with confidence in such conditions, it must meet certain requirements. Let’s consider these requirements depending on each factor separately.

Choosing the brand and model of the screwdriver

One of the most popular models in 2020. Is AEG BS18C2BL LI-402C. It has a solid torque of 65 Nm and 4 Ah batteries. One of the main features is that it is also brushless, which means that the service life of its motor will be much longer than that of its brush counterparts. There is also an extended 6-year warranty upon purchase at Vseinstrumenty.Ru. To get it, you just need to register the screwdriver on the aeg-powertools.Eu website. This is done for free.

AEG BS 18C Li-402C

The Makita DDF458RFE screwdriver, which has 91 Nm, is also popular, but the batteries are less capacious here. 3 Ah. As you can see, AEG wins in capacity, but Makita’s torque is much higher.

With 5Ah batteries, there is an AEG BSB18CBLLI-502C screwdriver. This is essentially the same brushless device from AEG that was discussed above, but with more capacious batteries, thanks to which the holes with it will turn out to be slightly larger.

AEG BSB18CBLLI-502C

If the above models seem expensive to you, but you nevertheless do not want to give up the idea of drilling ice with a screwdriver, then spit on everything that I wrote above about the battery capacity and an additional handle, and get yourself, for example, such device: Bosch GSR 18-2-LI Plus Professional. Yes, with it you will only drill about 50-70 holes, since the capacity of its batteries is only 2 Ah. Also, it will have to be held tighter, since there is no additional handle. But it costs one and a half to two times cheaper. Therefore, those who are not so active on winter fishing can get by with them.

Well, I think this is where the article can be ended. I hope I helped you with your choice. Read also my other articles on this site! Until next time and happy shopping!
