Production > Handheld Drills
|
 A handheld drill uses a multiple-cutting-edged
rotating tool to remove wood and produce a hole in the stock. Normally, drills have variable speeds and feeds.
Operator Involvement
The drill operator may or may not be a skilled worker. The common drill is often used by anyone in the shop and injuries can
occur because of carelessness. The operator must position the stock, install the drill, operate the drill, and maintain
housekeeping. The operator also must also change speeds and feeds when required. |

Potential Hazards:
-
One of the most common causes of accidents
involving
a drill is poor operator judgment. Often the
operator will attempt to hand-hold the stock while
drilling. When the drill enters the work, it can catch
and twist the stock from the operator, which results in
an uncontrolled rotating piece of wood. Other
point-of-operation hazards include the rotating drill,
which is rarely guarded, and hot chip generation.
-
The only reason this machine is less hazardous than
others is because of its simple operation; nevertheless,
familiarity with its operation is required.
Possible Solutions:
-
Guarding at the point of operation is difficult
because of the nature of the drilling process. The
drill gradually feeds into the work, it is changed
very often, chips must be able to escape, and the
stock must be moved around. All of these factors reduce the
possibility of using guards on the drill. If
guards are used, they probably will have to be
removed during the actual drilling process. Whenever
possible, a hold-down fixture should be used rather
than the hands.
-
Good housekeeping and operator training are
absolute musts.
