Replacement Carbide Cutter





There is one problem, yes… a problem with the cutter-it is very hard to tell when it’s time to replace it.  I have been using the cutters for almost 100% of my hollowing and have used them for both hogging out wood and for making finishing passes to clean up stray tool marks.  After many, many vessels and dozens of hours of use, I have finally started to see some deterioration of the edge and some fuzzy grain.  Fuzzed-up grain is usually a good indicator of a dull tool.  However, the only time I see any fuzzed-up grain is when I am using the cutters in the “scraping” mode-usually when undercutting a shoulder.

Another consideration is that I want to take advantage of the entire 3600 sharp edge before I discard the cutter.  So how do I differentiate between that which is used and that which is still sharp?  (No, you can’t mark it-I haven’t found anything that will stay on carbide.)

I’ve found a straightforward solution to both problems:  I simply loosen the torex screw and randomly expose a new edge every time I start a new vessel.  Then, after I have turned a number of hollow forms and used the cutter for dozens of hours, I can just assume that the entire circumference is dull and replace it with an inexpensive new cutter.
