I started my business in the mid 1980’s, and since then some things have changed as far as what is available for cutting tools used in CNC Swiss machines. Navigating the many choices is not always easy, but necessary to control costs. With every job you must decide which CNC swiss tools are the best fit.
There are many insert tools manufactured, but not all of them are a good fit for CNC Swiss. The size of the radius, the width of the tool, and the grind of the lead angle and rake are not the same for all manufacturers. If you have found a good one for you keep using it. If not try NTK, or Utilis. The real question is always when to use inserts and when to used braze carbide.
