摘要： A portable, hand-held tool for rolling a flange on metal sheet comprises a pair of handles pivoted together, the handles bearing a pair of parallel rollers which are moved together on approach of the handles and are drivable in rotation, the rollers having opposed portions of greater and lesser diameter so that on clamping of a metal sheet edge between the rollers and rotation of the rollers a flange is formed in the sheet edge. The handles may carry a device for setting the separation of the rollers at a desired value.

摘要： 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.
