TungTap -Brake disc- AB070
IMPROVED TOOL LIFE
Conventional taps experienced wear and chipping due to chip clogging, resulting in short tool life. The AB070 grade, which offers excellent heat resistance, suppresses wear, while an edge treatment optimized for cast iron machining helps prevent chipping. As a result, tool life was extended
