Those bits that come with the inexpensive Hand Impact drivers are pretty
much worthless. I have two hand impact drivers, a 3/8 drive, and a 1/2"
drive. They both were purchased back in my motorcycle repair days. The 3/8
drive has the square drive projecting from the handle, and bits that fit
onto the square drive like a socket. They are very high quality and hold up
very well.
The 1/2 inch drive has a chuck that fits the square drive, and the small
bits go in the chuck. The small bits are of poor quality and break
frequently. I might consider them consumables. Lots of spares are needed.
The main thing to remember, is to keep down pressure on the handle, and
don't let your skin creep up onto the hammer striking area. Make sure to be
square and plumb before you strike with the hammer. They will take Japanese
motorcycle case screws out when nothing else will work. Be sure to exactly
match the bit to the screw heads. There is Phillips, Reed & Prince,
Posi-drive, and possibly more, as well as U.S.S., D.I.N., and I.S.O. tapers
on the heads.
What I know.
