TungDrillBig – Shaft – AH725


TungDrillBig offers drill diameter sizes up to 80mm as standard items, which is larger than the competitor’s maximum available diameter. Therefore TungDrillBig can significantly reduce the number of boring passes required afterwards and the total machining time compared to the competitor. TungDrillBig allows highly stable machining even on curved surface due to its ideal shape of cutting edge.
