TungDrillBig – Sleeve – AH725
IMPROVED TOOL LIFE
TungDrillBig is applicable up to φ80mm machining, which is larger than the competitor’s maximum allowable drilling size in their standard series. Thus TungDrillBig can reduce the number of boring processes required afterwards, leading to shortening of its total machining time compared to the competitor. AH725 with “Premiumtec” prevents welding and chipping even when machining stainless steel, resulting in stable and longer tool life.
