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:   

  • 3/8 inch cutter with rod - 40 degree bevel (Best used for cleaning out mortises and sockets). Comes attached to a 5/16 inch diameter, 7 inches long, unmarked rod.  The cutter is attached to the rod with a 6-32 inch threaded end screw with a hex head.  Cutter head only fits a 6-32 inch threaded screw.  

  • 1/2 inch cutter with rod - 25 degree bevel (Best used as a general purpose cutter in soft or hard woods).  Comes attached to a 5/16 inch diameter, 7 inches long, unmarked rod.  The cutter is attached to the rod with 6/32 inch threaded end screw with a hex head.   Cutter head fits both a 6/32 inch threaded screw and a 4 mm threaded screw.

  • 7/16 inch cutter with rod - 20 degree bevel (Best used for marking in soft woods). Comes attached to a 5/16 inch diameter, 7 inches long rod etched with inch and milimeter markings.  The cutter is attached to the rod with a 4 mm threaded end screw with a phillips head.   Cutter head fits a 6/32 inch threaded screw or a 4 mm threaded screw. 

  • 5/8 inch cutter with rod - 35 degree bevel (Best use when marking for angled dovetails).  Comes attached to a 5/16 inch diameter, 7 inches long rod etched with inch and milimeter markings. The cutter is attached to the rod with a 4 mm threaded end screw with a phillips head.   Cutter head fits a 6/32 inch threaded screw or a 4 mm threaded screw.

Marking gauge cutter

The marking gauge cutter performs extremely well, easy to use and easy to set.

Very sharp!!!

Even after sharpening my old cutter wheel I was still getting poor results—tearing cross grain—the RC wheel is much sharper and cuts a clean groove in which to register a chisel. Great tool.

Recommend it for those who are looking for something better than a regular gauge.

Probably the best marking gauge on the market today. Feels solid and robust in the hand. I got all the cutters, and thus it become very versatile tool. What I like about it is that it is not only a marking gauge but it is a cutting tool. Having sharp cutters, I am getting very deep and clean marks on the wood(that is very helpful if you saw or chisel away on that line). Can be used as a depth gauge as well, where a router plane can't reach. Looks nice and shiny.
