Corner radius milling cutter SS4P30 series

indexable insertroughingshoulder

・Employs a fine carbide substrate with an excellent balance between wear resistance and toughness and the new "AJ Coating" to provide improved wear resistance and chipping resistance. ・ Highly versatile with excellent wear resistance and chipping resistance when machining steel materials with hardnesses of 30 to 50 HRC. Features ・Smooth surfaced α-Al2O3 layer with improved chipping / welding resistance brings less sudden-tool-edge-chipping. ・Machining efficiency is improved for high-speed, high-feed-rate rough machining by using the hard-layer with fine columnar structure.
