Specifically, the PS21-2A. The item I just bought does not hold
all of my quickchange drill bits properly. At the same time, my
Bosch I-Driver holds the same bits perfectly. I really really like
this drill, but cannot accept the chuck problem. Anyone know about
it, like whether it is part of the design, or is it more likely a
I suppose taking it back to the store would more likely get one
from the same lot. Then again, I won't have to wait to find out.
It could be the chuck. Take it to an authorized Bosch service center
and they will replace it under warranty. I purchased a Bosch cordless
tool set years ago. The blade for the sawzall would fall out. The
quick-release had a part missing and they replaced the quick-release
with a new one.
They should pop in and out no issues. Is there a piece of packing
styrofoam or something crammed into the bottom of the chuck? There
should also be a ball you can see when the chuck is closed. Is it
As I noticed today, the thing firmly grips the very short 1" screw
bits without using a magnetic holder, a bit with tiny cuts on each
of the its six corners, providing an extremely short distance from
the handgrip to the screw (assuming the workplace allows it). The
problem might have something to do with their effort to also grip
those 1" bits.
This tool (Bosch driver PS21-2A) is supposed to hold regular drill
bits, the kind that require a ball detent.
I might just work around it by adding a thin coat of super glue
(or whatever) to the shanks that do not stay put.
I am going to try making a long E6 beveled bit into a short type
C6 notched/nicked bits, by chucking and spinning the far end and
very lightly using a cutoff tool to make six tiny cuts on the hex
shank. Hopefully to convert at least one of my magnetic E6 type
bit holders into that C6 type shank. And if that works, then
convert my Snappy drill bit adapters. Not sure exactly what the
hex grooves should look like, whether they must be the same as the
tiny cuts in a C6 bit. If it works, it should be great, the weird
chuck holds the short C6 type bits tightly.
