Its very convienent to switch out marking gauge cutter sizes by just removing the rod with cutter attached and replacing it with a different size cutter attached to a rod.  Therefore, we offer our replacement cutters with rods.  These rods are designed to work with either a Cosmanized or a Rob Cosman marking gauge.  They should fit any marking gauge that accepts a 5/16 inch diameter rod, but we cannot guarentee that.

All of our cutters come pre-sharpened.  We sharpen these on a CBN grinding wheel which also flushes the face of the screw that holds the cutter to the with the face of the cutter.  

We offer four different sizes of replacement marking gauge cutters with rods.  Each cutter is a different size and has different bevel angles so that you can use the right cutter for the right job.  Our rods come unmarked or etched with inch and milimeter markings.  See below for details:
