XR utility blades have the same function as the standard Medium duty utility blades, but have a longer edge for cutting up to 1/2” thick substrates, including foam board and similar materials. While not normally needed in an Excalibur, XR blades can be used when cutting relatively thick materials is a challenge. Install the Excalibur XR Blades just as you would a normal blade. Compatible with the Keencut Excalibur 5000 Cutter
and SteelTrak cutters.
