Hi All

Saw this on the Argos site "Bosch PSB 14.4V-i Cordless Impact Drill with
Turbocharger".

It claims;

(a) Battery recharges in just 15 minutes with Bosch Turbocharger!

How does that work, and what does it do to the poor batteries?

(b) Revolutionary impact mechanism for maximum drilling power, in concrete
and hard materials.

What's revolutionary about it?

Anyone know?

Probably pulsed charging of some sort.

Every fast charger reduces battery life IMHO.

Maybe the charger technology from the bosch pro-tools has made it to
the diy stuff. The pro charger/batteries are first class. I have a
14.4V drill and 14.4V impact driver - they can both be worked hard day
after day. I leave the not-in-use battery on the charger all the time
(only swapping cells as one begins to slow) - which is meant to be ok
nowadays.

You can get charger ICs that both measure the cell temperature
and look for the small reduction in the cell voltage when the
cell is charged. When this is detected, the charger switches
from a high current charging to a low current trickle charge.
Likewise, if the temperature gets too high, it reduces the
charging current.

These ICs are used in the more expensive chargers and have
more features than I've described, like maximum charge timers,
etc. They can be kinder to the batteries than the "3 hour"
cheapies that can over-charge the batteries if they are left
charging for greater than the specified time.

(b) Revolutionary impact mechanism for maximum drilling power, in concrete

The impact mechanism goes round in circles, behind the drill
bit :-)

So it moves the drill bit in and out? Rather than moving the chuck in and
out? How does it compare to an SDS?

A turbo charger would be pretty useless for a battery powered drill.

And just how do you think this could be achieved since the chuck grips the
drill bit tightly?

SDS drill bits are driven by flutes for just that reason that they can be
'hammered' without having to move the extra weight of the chuck.

Then someone goes and puts a 1m bit on the drill.

Hope you had a nice holiday. Your fan club awaits, they've
been rather quiet in your absence, and they're beginning to
strain at the leash, and slobber.

Someone missed the smiley and the pun on "revolution-ary"...

I've no idea what is "revolutionary" about the Bosch
mechanism. It must be somewhere behind the drill bit, as is
the chuck and motor. A "revolutionary impact mechanism" could
well imply it goes round? :-)

This drill is new. Bosch imply it is clearly different to normal percussion
and SDS hammer mechanisms. Their web site do not explain the mechanism.

You're the senile one, old boy, if you don't know how a three jaw chuck
works.

It's sad that after all your posturing on cordless drills etc you haven't
a clue how they work.
