These wedges are part of the UJK Cam & Wedge set available separately. They have great potential in many workholding situations.
The wedges taper from 32mm to 27mm over a length of 200mm. They are CNC cut from 20mm thick HDF Valchromat. This material is very durable and easily tough enough to withstand gentle tapping with a hammer to lock the wedge. Using two wedges acting against each other ensures the applied force is at 90° to the edge of the workpiece.
