43-046 Convex Style Delta Carbide Shaper Cutter in Box NEW. Delta Carbide shaper cutter. I am a hobbyist. I collected nearly a full set of the carbide shaper cutters made by Rockwell and Delta. I am getting old and I am selling my big Delta shaper and these are a little big for my router table. Many of the cutters I have are new or barely used. All are very sharp and without damage.  I have over a hundred of these cutters. If you have one in particular you are looking for let me know.
