Gib-80 Replacement Gibs for 50mm IS58-Series Rebating Heads

Description

The IS58201 provides replacement Gib-80 gibs — the precision steel wedge clamps that secure carbide inserts in IS58-series 50mm rebating cutter heads. In rebating head designs that use gib clamping rather than Torx screw fasteners, the gib wedges against the back of the carbide insert under screw pressure, locking the insert firmly in its seat and transmitting cutting forces through the gib to the head body. Gibs are subject to wear and deformation over repeated insert changes in production environments where IS58 rebating heads are used continuously for rabbet and step profile work. A worn or deformed gib cannot apply consistent clamping force, allowing insert movement during cutting and producing poor surface quality on rabbet shoulders and walls. The IS58201 Gib-80 is specified for IS58-series rebating heads with 50mm body width; confirm gib size and designation match the rebating head model before ordering. Maintain a supply of IS58201 gibs at the machine to enable fast insert replacement during production.
