Popular Dura Carb Grades

Dura Carb Grade Dura Carb Description Image

With its premium micrograin structure, Dura Carb is a versatile grade
Dura Carb
that can be applied in a wide range of applications.
Super strong substrate designed to handle high shock resistance. It
contains a larger percentage of cobalt which increases its resistance to
Dura Carb II shock. We recommend Dura Carb II in roughing applications and to add
coatings to improve tool life.

Dura Carb III This superior wear grade is excellent for low impact tooling. It is a
long-lasting substrate for ideal machining conditions.

Dura Carb IV Special ultra fine carbide grade for machining hard materials > 60RC.

Special submicron grade for high-performance machining of steel,
Dura Carb V stainless steel and difficult to machine materials, like titanium. It has
optimum toughness combined with very good wear resistance.

h6 Tolerancing

Fullerton uses the industry preferred h6 tolerance on all of its solid carbide cutting tool
shanks, with noted exceptions. The h6 tolerance is generally considered the industry
standard with regards to shrink fit holders, and it requires manufacturers to be
consistent in their processes to adhere to this tolerance.
