SPL geometry for modular drilling with low cutting forces in high temperature alloys, and non-ferrous materials
Four-facet geometry with four margin lands for perfect centering and hole straightness
Application:
Applicable for stainless steel and high-temperature resistant materials. The coating offers high hardness and excellent wear resistance as well as enhanced high-temperature properties. In combination with its tough substrate, this grade offers superior chipping resistance and is best suited for metastable machining conditions.
