More power than I ....

Yes, a new cordless screwdriver was needed, my Metabo 12 Volt and 14.4 Volt Bosch my have passed away after many years, and with some Aabnutzungserscheinungen in battery performance (Metabo) and transmission (Bosch) to fight. The first question was, what caliber? I still have a 10.8 volt Maikta, the DF030DWJ who so require for all the smaller tasks as build furniture. Since the 12 Volt Metabo had anyway not much more power. The Bosch was much stronger.

But what I always lacked was a really powerful device with which you sometimes reinbekoimmt really big screw and the roof extension or with a 45mm Forstner holes drilled by thick rafters. So I chose the BHP458. The weighs not much more than my 10-year-old Bosch 14.4 Volt NiCd batteries.

The large auxiliary handle I found only just totally exaggerated, but when I then cheered 140x12mm Spax screws into solid wood for a Hochbettbau, I quickly realized that this handle fully justified when one exploits the screwdriver within its means. The screw-called sunk the part even in 2nd gear. The hammer action I've also tested in a massive brick wall, also goes surprisingly well, no comparison to a blue Bosch hammer, but a 0815 impact drill can not also.

Benefits:

- Extremely high torque
- High speed in second gear (2,000 rpm) ensures excellent drilling performance
- Speed ​​precision adjustment
- Torque adjustability
- Extremely short charging time with the quick charger
- High-quality chuck with mounting to 13 mm, as is purely a Mörtelrührer / Color Mixer
- Battery level indicator
- Useful Schlagborfunktion
- Very solid processed

Disadvantages:

- Torque is up 10Nm adjusted, after that comes the drill and you get the full package. So you have to watch out at 90 Nm hard, for example, when tilting, can be hurt, or damage the workpiece or machine. These are enormous forces, I once just knocked down at an 8mm Spax screw with Torx recording head.
- No disadvantage of the screwdriver, but my charger is noisy, the fan does not seem to optimally balanced and rattles. Since it does not apply to the screwdriver, I prefer starting from nothing.
- Quite a spark when the screwdriver is decelerating at low load = high speed. Underload no problem. Does not affect the performance of the device, we'll see how this affects the durability.

Conclusion:

This gives an extremely strong and solid wrench, which dissolves very difficult tasks. Who needs more torque eh takes an impact wrench. I know of no sensible application would require of a cordless screwdriver more power. The thing completes my range upwards. Who exploits the power of the wrench, should bring your own a little power and with sense and reason to works go (When I read here that people wanted to provide answers to their studs and surprised that the spindle backup shears, I can only head shake) for all small stuff does the mentioned little Makita, the rest creates this machine with ease. I would buy the wrench again, very strong buy recommendation.
