Ring and disc cutter

The ideal ring cutting device for shop and assembly work.

The device will cut properly, neatly, true to size and with a straight edge, all materials suitable for cutting, such as rubber, leather, felt, cardboard, plastics, graphite bonded with smooth metal foil and similar stock.

The cutting table consists of 20 mm thick lumber-core plywood mounted on two dovetail battens.

How to use the cutter

For first use, the cutter locating unit will be guided from below through the hole arranged at the centre of the cutting table, and then fastened underneath the table board.

A hole of 8 mm diameter will be provided in the material to be cut. After setting the knife to the desired diameter by means of the steel rule, the cutting arm has to be fastened to the stud bolt projecting through the material. Depending on the material to be cut, the knife bar is passed around the spindle several times with adapted hand pressure, until the material is completely severed.

For dimensions and weights please refer to the datasheet
