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
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.
