Hitachi DS12DVF3 Screwdriver Reviews
Virtues
- Conveniently lies in the hand. Not heavy. Quite a powerful tightening torque for its price. Easy and powerful flashlight included. Convenient and not bulky case.
disadvantages
- An improperly-designed charger that comes with the kit (produces a too high charging current of 2.6A, thereby killing batteries pretty quickly)
Comment
If you need a short battery charging time, and not their durability, the charger does not need rework. If you need first of all battery life, then the charger needs to be disassembled, vypayat trimmer resistor (there is one 10Km) and solder trimmer 150Kom solder. Solder better with a low-power soldering iron with a thin sting, so as not to overheat adjacent elements. 0.65A.A charge time before rework 40 minutes, and after rework about 2 hours. And yet, the Ni-Cd batteries must be fully charged, and allowed to cool before charging if they have warmed up after work. And you need to discharge the batteries until the screwdriver motor stops spinning or when the lamp of the flashlight is barely lit. Also, a deep discharge is extremely harmful to the batteries. By following these rules you can tighten a lot more screws!

Virtues
- Comfortable, lightweight, good weight distribution, it feels like a continuation of the hand.
- Includes a convenient case, charger, flashlight, 2 batteries, a set of bits. At the very Shurik swivel hook, it is convenient to hang up for the pocket of trousers or on the belt, there is the same bit holder. Another one on the case itself.
- Rubberized body (popularly called sneaker design) saves from splits when falling from relatively low altitudes.
disadvantages
- ACCUMULATORS are some kind of bjaka on noname banks ... they died after a couple of months of intensive professional use. Trained correctly, not the first and not one shurik use.
- The charger stinks burnt insulation when charging batteries. Gives out too much current for fast charging (only 25-35 minutes). Can batteries die because of this?
- Plastic cartridge - collapsed.
Comment
One new battery costs about one and a half thousand, i.e. It is easier to buy a new shurik :) But I gave my money for restoration - all the banks were changed, now my batteries have a capacity of 2 Ah versus 1.4 Ah in stock.
The next step is to replace the cartridge ...
Can be recommended for home use. For professional purposes is not suitable because of incomprehensible batteries and cheap cartridge.
P / S. After 2 years of almost uninterrupted work in dust, dirt, in heat and cold (professionally we are engaged in installation), the shurik died, or rather the button died, and the button is not easy there! All in chips :) Passed in for repair.
Shurik served faithfully and truly, paid for itself 100 times, although when I was young I spoiled my nerves with my batteries. And now Hitachi has released a 2nd revision DS12DVF3? there and batteries like normal :)

- We are talking about DS12DVF3-TB (!) - this device has an increased battery capacity to 2 A / h.
- + Fast rotation speed. There is an increased speed for drilling. Light. Conveniently lies in the hand. There is a swivel hook for hooking the belt / pocket. Convenient case.
disadvantages
- What would the batteries serve for a long time, you need to immediately redo the charger. The site http://www.mastercity.ru/showthread.php?t=431&page=14 has all the necessary information. Not the longest-lived batteries (judging by the reviews) (!) BUT the reviews discuss 1.4 A / h batteries, I don’t know if the quality of the batteries improved by 2 A / h, time will tell (it will be visible after 2 years).
Comment
I do repairs at home. A lot to twist. The only BUT, most often I do not tighten the screws to the ratchet (this saves battery power), because for the time being mostly had to work with soft materials. On average, 1 battery lasts for 8 days of use. Compared with cheap devices (up to 2.5 thousand), compared with them, Hitachi is the leader in convenience.

Virtues
- Excellent ergonomics, rubberized body, well balanced, powerful enough, fast charging of batteries, flashlight included. Well, just a beautiful and high-quality thing.
disadvantages
- For drilling, special hex drills are required, otherwise they turn in a chuck with a good load, as you do not hold. Batteries require a certain relationship to themselves, judging by the reviews here, charging instructions are either not read or forgotten.
Comment
Good model, suitable for home use and for work. Subject to the rules of operation prescribed by the manufacturer will last a long time.

- All merits are listed. Just agree with previous speakers.
disadvantages
- Achilles heel of this machine - too fast charging! In the presence of 2 acc. Included, there is no sense in it, it only kills batteries! The problem is solved by replacing a 10kΩ alternating trimmer resistor with a constant 82-100kΩ in the memory. At the same time, the charging time is increased to 1-1.5 hours, prolonging the life of the acc-rov 1.5-2 times.
Comment
A good machine for the money for not very heavy prof. works

- Cool machine, comfortable, powerful, batteries stand well, for 100pcs. weave enough at a time, a convenient case, a flashlight can be very useful, you can dock akk before charging, a set of spare bits, as well as a clip for wearing on a belt, and the price is not exorbitant
disadvantages
- Among the shortcomings, I note a weak cartridge, and insufficient power when drilling meteall
Comment
He used intensively throughout the year in heat and cold, in unsanitary conditions, Shurik repulsed the money spent on him. Therefore, I recommend!
