General specifications
The Wilton Model 1230 is a powerful and
versatile radial arm drill press. The drill head is
mounted on an arm and can move along the arm to
position the spindle over the work piece. The arm,
itself, can be rotated on its support column to allow
centering the spindle over the work piece.
Drilling can be performed manually or with
power assistance. In addition, parameters of RPM,
power feed rate and drilling depth can be pre-set by
the operator, using controls conveniently positioned
on the drill head, to allow any hole to be drilled using
power feed.
A precision machined box table is delivered with
the Model 1230 to allow convenient positioning and
clamping of smaller work pieces. The box table may
be removed from the base to allow larger workpieces
to be positioned and clamped on the precision
machined base, itself.
