Applications
–– For all steel and cast iron materials as well as for stainless
materials and materials which are difficult to machine
–– For drilling, spot drilling on inclined or convex surfaces, t
chain drilling
–– Ideally suited for use in general mechanical engineering, t
the automotive and mass production industries, as well as t
in aerospace applications
The benefits for you
–– Increase in productivity thanks to higher work values
–– Low hole tolerance due to the optimum balance of forces
–– Cost reduction:
•t 4 real cutting edges
•t Higher cutting parameters
•t Saving on additional subsequent operations
–– Excellent surface quality thanks to wiper edge at the t
hole diameter
–– High level of process reliability thanks to positive locking
of the indexable insert
