Summit Machine Tool
Radial Drills
Description
Summit® Radial Drills are designed and manufactured to provide the highest level of rigidity, strength and ease of operation. The radial drill arm is manufactured in a box form with heavy cross ribbing to give maximum stability. Raising and lowering the arm is accomplished by a crown mounted motor with conveniently located push button controls. The base is an extra-large casting with heavy internal webbing for additional support.
Every Summit® Radial Drill is designed and manufactured to provide the highest level of rigidity, strength and ease of operation.
