ABSTRACT:
A hole tapping device having a motor driven tapping tool with a bracing frame for resisting reverse torque on the motor frame caused by resistance of the rotation of the tapping tool within a bore being tapped. The bracing frame has adjustable arms which provide adjustment in the radial and angular direction and which clamp stationary protrusions on the workpiece with rollers to hold the bracing frame against rotation in both directions about the axis of the bore. The adjustments of the frame provide great geometric versatility. The rollers provide for a smooth translation of the motor and bracing frame along the axis of the bore being tapped. A single coupler and a series of inserts allow for a series of differently sized tap tools to be driven through the use of a single coupler.
