“The best grade is a grade you have now”
When a new insert (solid carbide tool or replaceable
cutting head) is developed, it is necessary to decide
from which grade it will be produced. The answer
to this question depends on the insert’s designated
application and this represents a starting point for tool
designers in their work. Grade properties and their
relative hardness-toughness ratio will be the main
determinants to take into consideration.
In some cases, stock availability and delivery
terms may be the significant factors in the
decision-making process.

As people engaged in production like to say, the best
carbide grade is the grade that you have in your stock.
This statement can be applied to the cutting tool as
a whole; it is probably true if it relates to a production
situation that requires an immediate decision. However,
productive process planning - or effective tool stock
management - requires a more in-depth applicative
analysis of the pros and cons of the proposed
carbide grades.
