Professional Power Drills for Tradesmen
All power-driven tools, but especially the
power drill, make work easier for the woodworker. Most drills
are pretty much the same, regardless of size and make. They
have a motor, trigger switch and chuck to hold the bit. The
jaws within the chuck hold the bit in place to prevent it
from slipping once locked. The jaws are locked with the aid
of a chuck key, which you turn clockwise to lock, and anti-clockwise
to unlock. More information on this can be found in the article
below.

Drills: Is There a Bit of Difference?
An interesting read from ECM on recognising the differences
between a consumer drill the do-it-yourself buyer uses and
the professional type an electrician uses daily to make a
living? A quick answer is: The professional power tool is
designed to be more powerful, last longer, and perform better
under stress than its consumer counterpart.
