I seem to have this problem only when driving exterior combination drive
screws (the screws that can be driven with a #2p or a square drive bit). If
you are using these type screws a there is special bit - called a posidrive-
that has both features of a square drive and #2p. It works best. Don't
forget to lube the screws-bath soap will work in a pinch. Your 14.4 will
perform much better. - dave

Does anyone have a preference for drill driver bits, specifically
Robertson
#2. I've been driving quite a few screws the last few days and I've gone
through a box of those damn Vermont American bits. Some screws seem better
than others, but overall the bit seems just a tad too small for most
screws.
After about 10 screws the bit starts to get rounded off and the screw
heads
start to look like the Star of David. I'm driving these into spruce with a
small pilot hole, so nothing too strenuous. I've had to finish off quite a
few screws by hand, as my screwdriver grips better and my 14.4 drill is a
little wimpy for the longer screws.

I don't know if it's the bits (likely), the screws or if my technique is a
contributing factor. I tried to drill out one of my Star or David screws
and
all I did was melt the drill bit, so the screws are plenty tough. BTW, be
careful drilling screws out of Particle Board, almost had a nice little
fire
going. I was sure relieved that I did not have to throw water on it and
swell up my Particle Board.
