ABSTRACT:
A nibbling tool for sheet material e.g. metal or plastics material and attachment to a power tool e.g. air or electric drill or air motor is disclosed. The structure of the tool permits a positive and easy change to be effected in respect of the cutting direction e.g. from the axial direction of the tool (for planar sheet) to a lateral direction for corrugated or contoured sheet. This change is effected by releasing a locking member externally of the housing and does not entail stripping down the tool. Likewise provision is made for a simple adjustment to optimize the stroke of the punch relative to the die.
